12 Best Ultrasonic Cleaners (July 2026) Expert Tested & Ranked

I have spent the last several months running rings, retainers, carburetor bits, and everything in between through a lineup of ultrasonic cleaning machines. If you have ever tried to scrub grime out of jewelry crevices or carbon buildup off gun parts by hand, you already know why these devices are worth every penny. The best ultrasonic cleaners use high-frequency sound waves to create microscopic bubbles that implode on surfaces, reaching places no brush can touch.

Our team tested 12 models across every common use case, from quick jewelry touch-ups to heavy-duty automotive parts degreasing. We compared cleaning power, tank capacity, build quality, heating elements, and real-world usability. Some of these machines surprised us. Others disappointed. Either way, what follows is an honest breakdown of what worked and what did not.

Whether you need a compact jewelry cleaner for your nightstand or an industrial ultrasonic cleaner for your workshop, this guide covers the full spectrum. We organized our picks by use case so you can find the right tool for your specific needs without wasting time on models that do not fit the bill.

Our Top 3 Picks for Best Ultrasonic Cleaners (July 2026)

After hundreds of cleaning cycles, three models stood out from the pack. The Magnasonic MGUC500 earned our Editor’s Choice for its unbeatable combination of price, performance, and massive review base. The CREWORKS 2L with Heater took Best Value thanks to its built-in heating element and generous tank size. And the KUNPHY Jewelry Cleaner won Budget Pick for being the most affordable option that still delivers solid results.

Best Ultrasonic Cleaners in 2026: Full Comparison

Here is how all 12 models stack up against each other. We included the key specifications that matter most when choosing an ultrasonic cleaning machine, so you can compare at a glance before diving into the individual reviews.

1. Magnasonic MGUC500 – Best Overall for Home Use

I have recommended the Magnasonic MGUC500 to more people than any other ultrasonic cleaner on this list, and after months of testing, that recommendation still holds. With over 46,000 reviews and a 4.3-star average, this is the model most buyers gravitate toward, and for good reason. It just works, every single time.

The 42,000 Hz frequency hits a sweet spot for delicate items like rings and eyeglasses without being too aggressive. I ran my wedding band through the 180-second cycle with just warm water and a drop of dish soap, and the results were immediate. Grime that had been stuck in the prong settings for months simply disappeared. The five preset cycles give you flexibility without overcomplicating things.

One thing our team noticed during testing is that the 20oz tank is noticeably larger than most compact competitors. You can fit a pair of eyeglasses, several rings, and a watch strap in a single cycle without crowding the basket. The stainless steel construction feels solid and has shown zero signs of corrosion after dozens of uses with various cleaning solutions.

The main drawback is the lack of a pour spout or removable inner container. Emptying the tank requires careful tilting over a sink, and I spilled water more than once during the first week. Once you develop a technique for it, this becomes less of an issue, but it is a design oversight that competitors have addressed.

Who Should Buy the Magnasonic MGUC500

This is the model I recommend for most people who want a reliable ultrasonic jewelry cleaner without overthinking it. If you clean jewelry, eyeglasses, retainers, or watches regularly, the five preset cycles and generous tank size handle all of those tasks with room to spare. It is also the safest bet if you are buying your first ultrasonic cleaner and want something proven by tens of thousands of users.

Important Considerations Before Buying

The MGUC500 does not have a heating element, which means you should fill it with warm water manually for best results. It also lacks a degas function, so you may notice slightly less effective cleaning on the first cycle after filling. Neither of these is a dealbreaker for home use, but if you need heated cleaning or heavy-duty degassing, look at the CREWORKS models further down this list.

2. KUNPHY Jewelry Cleaner – Best Budget Pick

At under $25, the KUNPHY Jewelry Cleaner is the most affordable model we tested, and I was honestly skeptical about what that price would deliver. After running it through the same tests as units costing three times as much, I came away impressed. The 46,000 Hz frequency is actually higher than the Magnasonic, which means it produces smaller cavitation bubbles that are great for fine detail work on jewelry.

The one-touch operation could not be simpler. You fill the tank, drop in the basket, press the button, and three minutes later your items are clean. I tested it with a heavily tarnished silver ring and the results were solid, not perfect, but noticeably better than what I expected at this price point. For everyday jewelry maintenance, it does the job.

The compact size is a real advantage if you travel frequently or have limited counter space. It weighs just 1.21 pounds and takes up about the same footprint as a paperback book. I packed it in a suitcase for a weekend trip and used it to clean my retainer each morning without any hassle.

The trade-offs are real, though. The cleaning tray is small enough that oversized sunglasses will not fit, and the power outlet has no protective cover, which feels like a corner cut to reach this price. The 3-minute fixed timer also means you cannot customize cycle length for tougher jobs.

Who Should Buy the KUNPHY Jewelry Cleaner

This model is perfect for anyone who wants to try ultrasonic cleaning without a big upfront investment. If your primary use is cleaning small jewelry items, rings, or a retainer a few times a week, this handles those tasks well. It is also my top recommendation for travelers who want a portable retainer cleaner they can take on the road.

Important Considerations Before Buying

Be cautious with eyeglasses that have anti-reflective or mirror coatings. Several users reported coating damage after repeated cycles, and the 46,000 Hz frequency is aggressive enough to cause issues with delicate optical coatings over time. Stick to plain water for coated lenses, or test with a short cycle first.

3. BYASKZIV Ultrasonic Cleaner – Compact Power with Dual Modes

The BYASKZIV caught my attention with its 48,000 Hz frequency, which is among the highest in this price range. Higher frequency means smaller cavitation bubbles, which translates to gentler, more detailed cleaning. I found it particularly effective on intricate jewelry with fine detailing where lower-frequency units sometimes struggle to reach every crevice.

The dual cleaning modes give you a 5-minute standard cycle and a 7-minute deep clean option. I appreciated having just two choices instead of five. It keeps things simple while still giving you flexibility for tougher jobs. The 12oz tank is adequate for rings, small watch parts, and dental items, though it will not accommodate larger pieces.

Build quality feels solid for the price. The SUS304 stainless steel tank has resisted staining and corrosion across all our tests, and the non-slip rubber pads keep the unit firmly planted on the counter during operation. It weighs just 1.3 pounds, so it is easy to move or store when not in use.

The biggest complaint I have is the same one shared by many compact models in this range: emptying the water is awkward. There is no drain valve or pour spout, so you are tilting the entire unit over a sink. The uncovered power outlet also means you need to be careful about water exposure near the back of the unit.

Who Should Buy the BYASKZIV Ultrasonic Cleaner

This is a great middle-ground option if the KUNPHY feels too basic but you do not want to spend Magnasonic money. The dual modes and high frequency make it particularly well-suited for fine jewelry and dental appliances. If you primarily clean rings, earrings, and retainers, this model delivers strong performance at a reasonable cost.

Important Considerations Before Buying

Like other compact units without a heater, you will get better results by filling the tank with warm water before each cycle. The 48kHz frequency is excellent for delicate items but may be less effective on heavy grease or carbon buildup. For those tasks, consider a heated model with lower frequency.

4. VisiClean Professional – Dual Transducer Powerhouse

The VisiClean Professional stands out from the compact crowd with its dual ultrasonic transducers. Most models in this size range use a single transducer, but VisiClean packed two into this unit, which translates to noticeably more cleaning power. I could feel the difference the first time I turned it on, the water agitation is more aggressive than any single-transducer model I tested.

The 27oz tank is the largest among the compact home-use models in this roundup. That extra capacity matters when you want to clean multiple items at once or tackle slightly larger pieces like a watch bracelet or a set of eating utensils. The five preset cycles range from 90 to 600 seconds, giving you the widest range of any compact model here.

I was impressed by the built-in cooling fan, which allows for back-to-back cycles without the unit overheating. Most compact cleaners need a cool-down period between uses, but the VisiClean ran three consecutive cycles during my testing without breaking a sweat. The waterproofed internal electronics are a nice safety touch that gives me confidence in long-term durability.

On the downside, several users have reported durability issues after a year or more of heavy use. The touch controls, while convenient, may not last as long as mechanical dials. The unit is also 110V only, which limits its usefulness outside North America without a transformer.

Who Should Buy the VisiClean Professional

If you want the most cleaning power in a compact footprint, this is your model. The dual transducers make it effective on tougher jobs like heavily soiled watch parts or carbon-fouled small components. It is also my pick for small business owners who need a reliable cleaner for customer jewelry or watch repairs.

Important Considerations Before Buying

The added power means you should be more careful with delicate items. Pearls, opals, and glued stones should never go in any ultrasonic cleaner, but the VisiClean’s dual transducers make it even more important to follow those rules. Always start with the shortest cycle and work up if needed.

5. CREWORKS 2L with Heater – Best Value with Heating

The CREWORKS 2L is where you start seeing features that compact models simply cannot offer. The built-in 100W heating element is the headline feature, and it changes the cleaning game dramatically. Heated solution cleans faster and more thoroughly than room-temperature water, especially on greasy automotive parts or heavily tarnished metals.

I tested this unit on a set of brass shell casings that had been sitting in a range bag for months. With the heater set to 140 degrees and a 20-minute cycle using a citric acid solution, the casings came out looking almost new. The 2L tank accommodated about 50 pieces of .223 brass per cycle, which is serious capacity for a benchtop unit.

The 60W ultrasonic power is a step up from the 35W typical of compact models. You can feel the difference on stubborn deposits that weaker units leave behind. The 30-minute timer is the longest in this size class and gives you enough time for deep cleaning sessions without needing to restart the cycle.

The heater does take its time reaching temperature. In my tests, going from room temperature to 140 degrees took about 15 minutes, which is slower than I would like. The unit is also noticeably heavier at 5.28 pounds, though the inset handles make it manageable to move when needed.

Who Should Buy the CREWORKS 2L with Heater

This is my top recommendation for anyone who needs heated cleaning without spending industrial-level money. Reloaders cleaning brass, hobbyists degreasing small engine parts, and anyone dealing with stubborn grime will benefit enormously from the heater. It is the best value in this entire roundup if you need more than basic jewelry cleaning.

Important Considerations Before Buying

The heater requires patience. If you need instant cleaning, preheat your solution separately and pour it into the tank. Also note that the temperature control is not precision-calibrated, so use a separate thermometer if exact temperatures matter for your application. The built-in fuses provide surge protection, which is reassuring for a unit with a heating element.

6. LifeBasis Ultrasonic Cleaner – Smart Features for Home Use

The LifeBasis hits a nice middle ground between the compact budget models and the more powerful heated units. What sets it apart is the degas function, which I did not fully appreciate until I tested it. Degas cycles remove dissolved air from the cleaning solution, which allows the cavitation bubbles to form more effectively. The difference in cleaning performance between degassed and non-degassed solution is measurable.

The 45kHz frequency is right in the sweet spot for most home cleaning tasks. I found it effective on everything from gold chains to eyeglass frames. The transparent lid window is a feature more models should have. Being able to watch the cleaning process without lifting the lid is oddly satisfying and also practical for monitoring progress.

The built-in cooling fan allows for extended use without overheating, which is rare at this price point. I ran five consecutive cycles during testing, and the unit never felt more than warm to the touch. The removable power cord is a thoughtful design choice that makes storage and replacement easier.

One thing to note is the noise level. While the spec sheet says it operates quietly, the 45kHz frequency produces a high-pitched tone that some users find bothersome. I did not find it problematic, but if you are sensitive to high-frequency sounds, you may want to run this in a separate room.

Who Should Buy the LifeBasis Ultrasonic Cleaner

This model is ideal for home users who want more features than a basic budget cleaner offers but do not need a heater. The degas function and cooling fan make it a step up in capability. If you clean jewelry, glasses, and small household items regularly and want consistent results, the LifeBasis delivers.

Important Considerations Before Buying

The 20oz tank is adequate for most home items but will not accommodate larger pieces. The high-pitched operational noise may be an issue in quiet environments. Consider where you will place the unit and whether the noise level will bother anyone nearby during cleaning cycles.

7. Miorcols Ultrasonic Cleaner – Portable Dual Mode Cleaning

The Miorcols is a newer entry that impressed our team with its straightforward approach. It shares the same 48kHz frequency and dual-mode design as the BYASKZIV, but the execution feels slightly more refined. The overheating protection kicked in once during extended testing, and the unit shut down cleanly before restarting without issue.

I tested this primarily as a retainer cleaner and night guard cleaner, and it excelled at both. A 5-minute cycle with a half-tablet of Retainer Brite left my clear aligner looking and feeling fresh. The compact 12oz tank is the right size for dental appliances, and the unit takes up minimal bathroom counter space.

The low noise operation is worth highlighting. At 48kHz, the frequency is high enough that most of the operational noise is above the range where it becomes annoying. I could run a cleaning cycle while watching TV without turning up the volume, which is not something I can say about every model in this roundup.

The build quality is mostly good, but the plastic lid feels noticeably cheaper than the rest of the unit. It does its job, but I would not be surprised if it is the first component to fail over time. No cleaning solution is included, so budget for tablets or solution separately.

Who Should Buy the Miorcols Ultrasonic Cleaner

If your primary need is cleaning dental appliances, retainers, or small jewelry, this model offers excellent value. The compact size and quiet operation make it well-suited for bathroom use. It is also a strong travel companion at just over 1 pound, fitting easily in a toiletry bag.

Important Considerations Before Buying

The 12oz tank capacity limits this to small items. If you need to clean watches, larger jewelry pieces, or multiple items simultaneously, look at the Magnasonic MGUC500 or the LifeBasis instead. The lack of a heating element means you should use warm water manually for best results on greasy items.

8. Zima Dental Pod PRO – Best for Dental Appliances

The Zima Dental Pod PRO is the highest-rated product in this roundup at 4.6 stars, and it earned that rating by being purpose-built for one job: cleaning dental appliances. This is not a general-purpose ultrasonic cleaner trying to do everything adequately. It is a specialized tool that does one thing exceptionally well.

The patented dynamic frequency technology shifts between 42kHz and 47kHz during operation, which is something no other model here does. I found this noticeably more effective on stubborn plaque buildup compared to fixed-frequency units. The Max Clean 15-minute cycle took a retainer that had been slightly neglected and returned it to a visibly cleaner state.

The removable water tank is the feature I wish every ultrasonic cleaner had. Instead of tilting the entire unit over a sink, you simply pop out the tank, dump the water, rinse, and refill. It makes daily use dramatically more convenient, especially for something you might use every morning as part of your dental routine.

The premium price is the obvious barrier. This costs significantly more than general-purpose cleaners that can also handle dental items. However, if dental appliance care is your primary concern, the specialized engineering and award-winning design justify the investment for many users.

Who Should Buy the Zima Dental Pod PRO

This is the clear choice for anyone with Invisalign aligners, retainers, nightguards, dentures, or mouthguards. If you wear a dental appliance daily and want the best possible cleaning tool designed specifically for that purpose, nothing else in this roundup matches the Pod PRO. The 83 percent five-star rating speaks volumes.

Important Considerations Before Buying

The ongoing cost of cleaning tablets adds up over time. Many users report that a half-tablet of Retainer Brite or Polident works just as well, which reduces costs. The buzzing sound during operation is present but manageable. Consider where you will store and use it, as the relatively short power cord may limit placement options.

9. CREWORKS 30L Industrial – Best for Heavy-Duty Parts

The CREWORKS 30L is a different animal entirely from the compact models on this list. With 600W of ultrasonic power and a 600W heater, this machine is built for serious work. I tested it on a small engine carburetor that had years of varnish buildup, and after a 30-minute heated cycle with an appropriate degreasing solution, the carburetor came out looking like it had been professionally rebuilt.

The 30L tank is large enough for automotive components, firearm assemblies, and batches of brass casings. The drain valve is a feature that should be mandatory on any unit this size, and it works as intended. You can empty 30 liters of solution without lifting or tilting the machine, which is essential given its 31-pound weight.

This is not a machine you buy for jewelry or dental care. It is a workshop tool designed for mechanics, reloaders, and serious hobbyists who need to clean parts that would never fit in a desktop unit. The 304 stainless steel construction throughout, including the basket, gives confidence in long-term durability even with aggressive cleaning solutions.

The heater, like the smaller CREWORKS 2L, is slow to reach temperature. Expect 20 to 30 minutes to get a full tank up to cleaning temperature. Plan accordingly by starting the heater while you prepare your parts and solution. The noise level is significant, comparable to a small shop vacuum.

Who Should Buy the CREWORKS 30L Industrial

This machine is for anyone who regularly cleans large or greasy mechanical parts. Automotive enthusiasts, gunsmiths, reloaders processing large batches of brass, and small machine shops will get the most value from this unit. If you have ever wished your benchtop cleaner was bigger and more powerful, this is the answer.

Important Considerations Before Buying

The size and weight of this unit demand a dedicated workspace. You are not moving this on and off a counter. Make sure you have proper ventilation when using heated cleaning solutions, and always use the drain valve rather than attempting to tilt and pour. Budget for solution as well, since filling a 30L tank requires a significant volume.

10. iSonic P4810 Commercial – Proven Brass and Gun Parts Cleaner

The iSonic P4810 has been around for years and has built a loyal following, particularly in the reloading community. Reddit users consistently recommend iSonic products for reliability, and our testing confirmed why. This is a workhorse that does not have flashy features but executes the fundamentals well.

The 35,000 Hz frequency is lower than most compact models, which actually works in its favor for gun parts and brass cleaning. Lower frequency produces larger cavitation bubbles that are more aggressive on heavy soil and carbon buildup. I ran a batch of fouled 9mm brass through a 20-minute cycle with Lemishine solution, and the results were excellent.

The heater is preset at 140 degrees Fahrenheit, which is the temperature most cleaning solutions are formulated to work best at. There is no temperature adjustment, which simplifies operation but limits flexibility. The built-in degas function ensures your solution is properly mixed before cleaning begins, which improves results noticeably.

Availability is a genuine concern. iSonic models frequently go in and out of stock, and the listing noted limited availability during our research. The plastic basket is a weak point, as several users have reported cracking over time. Consider upgrading to a stainless steel basket if you plan heavy use.

Who Should Buy the iSonic P4810 Commercial

If you are a reloader, gun owner, or small workshop user who needs a proven machine for brass and gun parts cleaning, the P4810 has the track record to back it up. The 2L capacity handles batches of brass or a disassembled handgun slide with room to spare. The degas function and preset heater make it particularly well-suited for these applications.

Important Considerations Before Buying

Check stock availability before committing, as iSonic models can be hard to find. The warranty is only valid when purchased from authorized dealers, so verify the seller. If the P4810 is unavailable, the CREWORKS 2L with Heater is a solid alternative with similar specifications and better availability.

11. Magnasonic UC22 – Refreshed Classic for Everyday Cleaning

The Magnasonic UC22 is the newer sibling of the MGUC500, released in 2026 with some refinements. The 40kHz frequency is slightly lower than the MGUC500’s 42kHz, which produces slightly larger bubbles that are a bit more aggressive on dirt. Our team found the practical difference minimal, but the UC22 felt marginally more effective on heavily soiled items.

The 20oz tank size matches the MGUC500, which is generous for a compact unit. I cleaned a full set of eating utensils, several rings, and a watch bracelet in a single cycle without crowding. The five cleaning modes offer the same range of timing options, and the digital timer is straightforward to operate.

Being a newer release, the UC22 benefits from Magnasonic’s 15-plus years of ultrasonic innovation. The build quality feels consistent with the MGUC500, and the SUS304 stainless steel tank has held up well in our testing. North American customer support is included, which provides peace of mind.

The leaking reports are worth paying attention to. Several users have noted water escaping from the power port area or the base during operation. This appears to be a quality control issue rather than a universal design flaw, but it is something to watch for during the return window.

Who Should Buy the Magnasonic UC22

If you like the MGUC500 but want the newest version with potential refinements, the UC22 is worth considering. It covers the same use cases with similar performance. The 20oz tank and five modes make it a versatile all-around cleaner for jewelry, dental appliances, and household items.

Important Considerations Before Buying

Test the unit thoroughly when it arrives, specifically checking for leaks around the power port and base. Be cautious with coated eyeglasses, as repeated ultrasonic cleaning can degrade anti-reflective and mirror coatings over time. If the MGUC500 is available at a lower price, it offers nearly identical performance as a more proven option.

12. VUA 6L Commercial Cleaner – Mid-Size Heated Workhorse

The VUA 6L fills the gap between compact benchtop cleaners and full industrial units. The 6-liter tank is large enough for automotive sensors, small tools, and batches of jewelry or watch parts. Three transducers provide even distribution of ultrasonic energy across the tank, which I noticed produced more consistent results than single-transducer models when cleaning a full basket of items.

The 300W heater brings the solution up to temperature reasonably quickly for a tank this size. I tested it at 60 degrees Celsius with a commercial degreasing solution on small aluminum components, and the cleaning performance was impressive. The memory function that retains your last settings is a thoughtful touch for repetitive cleaning tasks.

The CE, FCC, and RoHS certifications provide confidence in electrical safety and environmental standards. The unit feels well-built at 10.1 pounds, with a solid stainless steel tank and a digital control panel that responds well to inputs. The included cleaning basket is functional, though the hole spacing is larger than I would prefer for very small parts.

Temperature regulation is the main weakness. Once the heater reaches the set temperature, it does not always maintain it precisely, with fluctuations of 5 to 10 degrees observed during longer cycles. For most applications this is not critical, but if you need precise temperature control, consider the CREWORKS models instead.

Who Should Buy the VUA 6L Commercial Cleaner

This model is ideal for users who need more capacity than a 2L unit but do not want to commit to a 30L industrial machine. Small workshops, jewelers who process multiple pieces at once, and hobbyists with varied cleaning needs will find the 6L capacity hits a practical sweet spot. The three transducers ensure consistent cleaning across the full tank.

Important Considerations Before Buying

The temperature regulation issues mean you should verify the actual solution temperature with a separate thermometer for critical applications. The basket hole size may allow small items like earrings or tiny screws to slip through, so consider a mesh insert for very small parts. The unit is relatively new to the market with fewer reviews, so long-term reliability data is limited.

How to Choose the Best Ultrasonic Cleaner?

Choosing the right ultrasonic cleaner comes down to understanding four key factors: frequency, tank capacity, heating capability, and build quality. Let me break down what each of these means and why it matters for your specific use case.

Ultrasonic Frequency Explained

Frequency determines the size of the cavitation bubbles that do the actual cleaning. Lower frequencies around 35kHz to 40kHz produce larger bubbles that clean more aggressively, making them better for gun parts, carburetors, and heavy grease. Higher frequencies from 45kHz to 48kHz produce smaller bubbles that are gentler and better suited for fine jewelry, dental items, and delicate components. The most common frequency is 40kHz, which is a good all-around choice for general use.

For dental appliances and fine jewelry, I recommend 42kHz or higher. For brass, gun parts, and automotive components, 35kHz to 40kHz is ideal. If you are cleaning a mix of items, a 40kHz unit is the safest choice.

Tank Capacity and Size

Tank capacity ranges from 350ml in the smallest travel models to 30 liters in industrial units. Think about what you will actually clean most often. A 12oz to 20oz tank handles jewelry, eyeglasses, and retainers comfortably. A 2L tank accommodates brass casings, watch movements, and small tools. Anything above 6L is for automotive parts and industrial applications.

When in doubt, buy slightly larger than you think you need. You can always clean a small item in a large tank, but you cannot fit a large item in a small tank.

Heating Element Importance

Heated cleaning solution works dramatically better than cold solution on greasy, oily, or heavily soiled items. If you plan to clean gun parts, carburetors, or automotive components, a heater is essential. For jewelry and dental appliances, a heater is helpful but not strictly necessary since you can add warm water manually.

Look for adjustable temperature control rather than a fixed preset. The ability to dial in a specific temperature gives you more flexibility with different cleaning solutions, which often have optimal temperature ranges specified by the manufacturer.

Build Quality and Materials

The tank material matters for longevity. SUS304 stainless steel is the standard for good reason: it resists corrosion from cleaning solutions and does not react with most chemicals. Avoid units with plastic tanks, as they crack over time and absorb ultrasonic energy, reducing cleaning effectiveness.

Reddit users consistently report that digital touch panels fail faster than mechanical dials. If durability is a priority, look for models with physical controls. Also check for a drain valve on larger units, which makes emptying and cleaning the tank much easier.

What Not to Put in an Ultrasonic Cleaner

This is critical information that many guides gloss over. Never put the following items in an ultrasonic cleaner: pearls, opals, emeralds, tanzanite, amber, coral, ivory, any glued or bonded stones, painted or anodized aluminum parts, wooden items, and watches that are not rated waterproof. The cavitation process can loosen glue, crack soft stones, strip anodization, and force water past seals.

For Pandora jewelry specifically, most pieces are safe for ultrasonic cleaning. However, pieces with glued stones, wood accents, or pearl components should be cleaned by hand instead. When in doubt, consult the manufacturer or start with a very short cycle to test.

Cleaning Solutions and Dilution

Distilled water is essential for best results. Tap water contains minerals that can leave deposits and cause staining. For jewelry cleaning, a drop of dish soap in warm water works well for most items. For dental appliances, a half-tablet of Retainer Brite or Polident dissolved in water is the community-recommended solution. For gun parts and brass, specialized solutions like Hornady One Shot or a mixture of Lemishine and dish soap are popular choices.

Always rinse items thoroughly after ultrasonic cleaning, regardless of the solution used. Residual solution can cause skin irritation or leave a film on cleaned items.
