6 Best Ultrasonic Cleaner Solutions in 2026
We compared six ultrasonic cleaner solutions for jewelry, eyeglasses, dental items and engine parts on dilution, yield and intended use to help you pick right.
At a Glance
iSonic Jewelry and Eyeglass Cleaner Solution Concentrate
↓ See why we picked itAn ultrasonic tub does the shaking, but the liquid you put in it decides how well oil, polish residue, varnish or carbon actually dissolve. Plain water handles light dirt, yet a good concentrate helps break films that bubbles alone only loosen. The problem is that solutions are formulated for very different jobs, so a jewelry concentrate and a carburetor degreaser are not interchangeable.
We evaluated six concentrates based on product specs and buyer feedback, comparing the items each is meant for, the stated dilution or yield, the metals and materials it covers, and what each maker says about safety. The lineup splits into three jewelry and personal-care formulas and three parts formulas, with yields from a single capful per tank to up to 50 gallons from one 32 oz bottle. Always check your machine's manual before using any chemical, because some tubs and some materials do not suit certain liquids.
Use the picks to find your category first, then lean on the buying criteria and tables to compare dilution and yield. Never mix solutions, and rinse and dry what you clean.
6 Criteria to Look For Before Buying a Ultrasonic Cleaner Solution
Key buying criteria so you get the right fit the first time.
Match the formula to the job
The first split is between personal-care formulas and parts formulas, and mixing them up is the most common mistake. Jewelry and eyeglass liquids are mild, while engine-parts concentrates are built to cut varnish and carbon. The iSonic and Blitz are made for jewelry, the WoldoClean spans dental items and small parts, and the Tillbrook, Sylvan Hills and Qucship are for engine parts. Read the intended item list on the label before you pour.
Dilution ratio and yield
A stronger concentrate costs more per bottle but makes more liquid, so yield is the fair comparison. The WoldoClean makes 8 gallons at 1 to 40, the Tillbrook makes 8 gallons, the Qucship makes 9 gallons from 1 gallon, and the Sylvan Hills mixes at 1 to 250 for up to 50 gallons. A small tub uses very little per fill, so a high-yield bottle can last years. Measure carefully, because a 1 to 250 mix that is too weak cleans poorly.
Materials it is safe for
Ultrasonic solutions are not safe on everything, and the label tells you what the maker covers. The Qucship lists aluminum, copper, zinc, iron, steel, magnesium, brass and some plastics, and the Sylvan Hills lists aluminum, brass, copper and steel. The WoldoClean calls itself gentle on lens coatings. Avoid using any solution on soft stones, painted or plated parts, or glued items unless the maker says it is fine.
Tank size and use per fill
How much you pour depends on your tub, so match the bottle to the tank. The WoldoClean says one capful works in 8 to 64 fl oz machines, which suits home tubs. The iSonic is also dosed at one capful per use. Large tanks of several gallons use the parts concentrates, and in a small tub you would rarely finish a 128 oz bottle like the Qucship.
Safety, fumes and disposal
The liquid you use must suit the room you are in. The iSonic and Blitz list non-toxic, biodegradable formulas, the WoldoClean is non toxic and ammonia free, and the Sylvan Hills claims no harsh fumes. Parts formulas are stronger, so use ventilation and gloves, and follow local rules for used liquid. Never mix two products together.
Rinse, dry and replace
Residue left on a part can cause spots or film, so every solution needs a rinse and a dry. The WoldoClean directions say rinse with clean water and dry with a lint-free cloth, and the Sylvan Hills includes a microfiber cloth. Replace the liquid when it looks visibly dirty, as the Sylvan Hills listing advises. A fresh mix cleans faster than a tired one.
6 Best Ultrasonic Cleaner Solutions in 2026
WoldoClean Ultrasonic Cleaner Solution Concentrate, 25.4 oz
About this pick
The WoldoClean is the most versatile concentrate in this group. One 25.4 fl oz bottle makes 8 gallons of ready-to-use liquid at a 1 to 40 dilution, and the listing says one capful per tank is enough for machines from 8 to 64 fl oz. It is non toxic, ammonia free and described as gentle on lens coatings.
The item list is the broadest here, covering dentures, retainers, aligners, mouthguards, eyeglasses, sunglass lenses, contact lens cases and dental trays in a few minutes. It also handles oil, grime and carbon from gun parts, razor and shaver heads, clipper blades, watch and clock parts, coins, brass and carburetor jets. The tradeoff is that a do-everything formula is a generalist, and delicate stones and plated items still need your own caution.
Use is simple, add a capful to warm water, run the cycle, rinse and dry with a lint-free cloth. Compared with the iSonic at one capful per use, it matches the simplicity but covers parts as well. Against the Sylvan Hills at 1:250, it needs more concentrate per gallon, though its wider item list may justify that for a mixed household.
Best for: Households that clean eyeglasses, dental items, razors and small parts with one bottle.

- Size: 25.4 fl oz concentrate
- Yield: 8 gallons at 1 to 40 dilution
- Use per tank: One capful in warm water
- Tank range: 8 to 64 fl oz machines
- Formula: Non toxic, ammonia free
Pros
- +Makes 8 gallons of ready-to-use liquid from one bottle at 1 to 40
- +The broad item list spans dental trays, lenses, razors, coins and watch parts
- +Ammonia free and non toxic, and described as gentle on lens coatings
- +A single capful per tank suits home machines from 8 to 64 fl oz
Cons

- −A 1 to 40 dilution needs more concentrate per gallon than the Sylvan Hills
- −Delicate stones and plated items still need your own judgment
iSonic Jewelry and Eyeglass Cleaner Solution Concentrate
About this pick
The iSonic concentrate is a purpose-made jewelry and eyeglass liquid. The listing describes a highly concentrated, American-made fluid that needs just one capful per use, so a bottle yields several sessions. It is non-toxic and biodegradable and aimed at gold, silver, diamond, watch and eyewear cleaning.
It promises to lift oils, dirt and tarnish from rings and settings and leave lenses with a streak-free finish. We would take the tarnish line cautiously, because ultrasonic cleaning mainly removes dirt and film, and tarnish is a chemical change. The listing does not state the bottle size or a dilution ratio for this version, so check the label before you plan your usage.
In daily use you add a capful to the tank, run a short cycle, then rinse and dry. It is a sensible companion for a jewelry tub, since the formula is gentle by design. Compared with the Blitz concentrate, it targets eyewear as well, and against the WoldoClean it does not list dental items or parts, so it is the narrower, more personal-care-focused choice.
Best for: Jewelry and eyeglass owners who want a gentle, dedicated concentrate used one capful at a time.
Check price on AmazonSpecs
- Type: Jewelry and eyeglass concentrate
- Dose: One capful per use
- Intended items: Gold, silver, diamond, watches, eyewear
- Formula: Non-toxic, biodegradable
- Origin: American-made
Pros
- +Dosed at one capful per use, so one bottle goes a long way for you
- +Formulated for gold, silver, diamonds, watches and everyday eyewear
- +Non-toxic and biodegradable formula that is also made in the USA
- +Aims for a streak-free finish on lenses as well as on jewelry
Cons
- −The listing gives no dilution ratio or size for this version
- −It does not name dental appliances or engine parts as intended items
- −Claims about removing tarnish should be taken with some caution
Blitz Gem and Jewelry Cleaner Concentrate Refill, 8 oz
About this pick
The Blitz is a gem and jewelry concentrate refill for ultrasonic machines. The 8 oz bottle is a concentrated form of the standard cleaner and is said to give eight times the use of a single bottle. The listing calls it nontoxic, non-abrasive and biodegradable, and it targets fingerprints, buildup and dullness on diamonds, emeralds and other stones.
The brand has made jewelry cleaners since 1912, a heritage fact that we mention without ranking on it. The listing speaks of jewelry and accessories and does not name eyewear, dental items or engine parts. Because it is jewelry-specific, it is a poor fit for tools, parts or heavy oil.
Using it is straightforward, dilute it according to the label, run your tub and rinse. Delicate stones such as emeralds are still risky in any ultrasonic tub, so a gentle formula does not remove the need for caution. Compared with the iSonic, it is a similar concept with an 8x concentrate claim, and next to the WoldoClean it covers far fewer item types, so it suits a jewelry-only routine.
Best for: People who clean only jewelry and want a trusted concentrate refill for an ultrasonic tub.
Check price on AmazonSpecs
- Size: 8 oz
- Concentration: 8x use from one bottle
- Formula: Nontoxic, non-abrasive, biodegradable
- Intended items: Diamonds, emeralds, jewelry, accessories
- Brand history: Since 1912
Pros
- +Concentrated 8 oz formula is said to stretch to eight times the use
- +Nontoxic, non-abrasive and biodegradable formula, per the listing
- +A long-running jewelry cleaner brand, in business since 1912
- +Clears fingerprints, buildup and dullness from gems and jewelry
Cons
- −Jewelry-specific, so it is a poor fit for tools or engine parts
- −Eyewear and dental items are not named in the listing at all
- −A gentle formula does not make emeralds or soft stones truly safe
Tillbrook Ultrasonic Cleaner Solution, Makes 8 Gallons
About this pick
The Tillbrook is a concentrated auto-parts formula that makes 8 gallons. It is aimed at carburetors, injection parts and other metals, and the listing says it removes dirt, varnish and gums from exterior and interior components. When paired with an ultrasonic machine it reaches cracks, crevices and blind holes that a brush cannot.
The listing says the formula is free from unnecessary harmful chemicals, and it is made in the USA. It does not list dental items, eyewear or jewelry, so it should not be your pick for those. The listing mentions mixing directions, but we would follow the bottle label exactly for the ratio.
In practice it belongs in a bench-sized tub, since 8 gallons of ready-mix only makes sense for larger tanks. Against the Qucship at up to 9 gallons from a gallon of concentrate, it yields slightly less, and against the Sylvan Hills at up to 50 gallons it yields far less. Choose it when you want a focused carburetor and varnish fighter and plan to clean small engines regularly.
Best for: Hobby mechanics who rebuild carburetors and injectors and want a focused degreasing concentrate.
Check price on AmazonSpecs
- Yield: Makes 8 gallons
- Type: Concentrate for auto parts
- Targets: Dirt, varnish, gums
- Intended items: Carburetors, injection parts, metals
- Origin: Made in USA
Pros
- +Makes 8 gallons of cleaning liquid from a single concentrate
- +Targets dirt, varnish and gums in carburetors and injection parts
- +Reaches blind holes and crevices when paired with an ultrasonic tub
- +Made in the USA, with a formula free from unneeded harsh chemicals
Cons
- −Not meant for jewelry, eyewear or dental items, only metal parts
- −Yields less per bottle than the Sylvan Hills at up to 50 gallons
- −Mixing instructions should be taken from the label and not the listing
Sylvan Hills 32 oz Ultrasonic Carburetor and Parts Cleaner
About this pick
The Sylvan Hills offers the highest dilution here, mixing at 1 to 250 so a 32 oz bottle makes up to 50 gallons of fluid. It targets carburetors, engine parts and small metal components and is called safe on aluminum, brass, copper, steel and other automotive metals. The listing claims no harsh fumes or corrosive additives.
The fluid should be replaced when it is visibly dirty, and parts are rinsed and dried with the included microfiber cloth. It is made and bottled in the USA and suits DIYers and engine rebuilders. The high dilution is a plus for yield, but it also means measuring carefully, because under-dosing a 1 to 250 mix leaves the solution weak.
The dilution makes sense if you run a large tank, and a small tub uses only a few teaspoons. Compared with the Tillbrook at 8 gallons and the Qucship at 9 gallons, it stretches much further per bottle. Against the WoldoClean at 1 to 40, it is far more concentrated, though it is aimed at parts and not at eyeglasses or dental items.
Best for: DIY mechanics who clean small engine parts often and want maximum liquid per bottle.
Check price on AmazonSpecs
- Size: 32 oz concentrate
- Mix ratio: 1 to 250 with water
- Yield: Up to 50 gallons
- Metals: Aluminum, brass, copper, steel
- Included: Microfiber cloth
Pros
- +A 1 to 250 mix ratio makes up to 50 gallons from a 32 oz bottle
- +Called safe on aluminum, brass, copper and steel, per the listing
- +A microfiber cloth is included for drying parts after rinsing
- +Made and bottled in the USA, with no harsh fumes claimed by the maker
Cons
- −Measuring a 1 to 250 mix carefully matters, as a weak mix cleans poorly
- −Aimed at engine parts, not eyeglasses, jewelry or dental items
- −The mixed fluid must be replaced as soon as it looks visibly dirty
Qucship Ultrasonic Carburetor Cleaner, Makes 9 Gallons
About this pick
The Qucship is a 128 oz heavy-duty engine-parts concentrate. The listing says 1 gallon of concentrate makes 9 gallons of cleaning fluid, calling it 8x concentrated. It targets carburetors, fuel injectors, generators, oil pans and pistons, removing dirt, varnish and other contaminants.
Its material list is the widest, naming aluminum, copper, zinc, iron, steel, magnesium, alloys and brass, along with plastic parts and coins. That breadth is useful, but you should still confirm compatibility with plated or painted parts. The listing also promises 24/7 customer support, a service claim we noted without ranking on.
The large bottle makes sense for a shop that runs a big tank every week. Compared with the Tillbrook at 8 gallons, it yields a gallon more, while against the Sylvan Hills at up to 50 gallons it makes far less. Pick it for the broad metals list and large single bottle, and skip it if you only clean a few small parts a year.
Best for: Shops and hobbyists who refill a large tank often and clean a mix of engine metals.
Check price on AmazonSpecs
- Size: 128 oz (1 gallon) concentrate
- Yield: Makes 9 gallons
- Concentration: 8x concentrated
- Metals: Aluminum, copper, zinc, iron, steel, magnesium, brass
- Also lists: Plastic parts and coins
Pros
- +One gallon of concentrate makes up to 9 gallons of cleaning fluid
- +Lists aluminum, copper, zinc, iron, steel, magnesium and brass
- +Covers carburetors, injectors, generators, oil pans and pistons
- +The large 128 oz bottle suits frequent refills of a big tank
Cons
- −A 128 oz bottle is far more than a casual home user ever needs
- −It makes less fluid per bottle than the Sylvan Hills at 50 gallons
- −Painted or plated parts need a compatibility check before use
How We Evaluated These Ultrasonic Cleaner Solutions
Each pick was assessed across 5 criteria weighted for real-world use.
Intended use and material coverage
We compared the items and metals each maker names. The WoldoClean has the broadest personal and parts list, the Qucship names the most metals, and the iSonic and Blitz stay with jewelry. We treated unlisted items as unsupported.
Dilution and yield
We looked at stated mix ratios and gallons produced. The Sylvan Hills leads at up to 50 gallons from 32 oz, the Qucship makes 9 gallons, and the WoldoClean and Tillbrook make 8 gallons each. Because sizes differ, we ranked on yield, not bottle size.
Safety and formula claims
We read what each maker says about toxicity, fumes and biodegradability. The iSonic and Blitz are non-toxic and biodegradable, the WoldoClean is ammonia free, and the Sylvan Hills claims no harsh fumes. We treated all claims as manufacturer statements.
Ease of use
We compared how simple dosing is. The iSonic and WoldoClean use a capful, the Blitz is a concentrate refill, and the parts concentrates need measured mixing. We weighted clear instructions heavily.
Ownership and value
We considered bottle size, extras and how each formula fits its class. The Sylvan Hills includes a microfiber cloth, the Qucship offers a large 128 oz bottle, and the Blitz has a history back to 1912. We did not rank on price, only on what each liquid delivers for its purpose.
How to Choose the Right Ultrasonic Cleaner Solutions
By What You Clean
Match the liquid to the item, since the wrong formula is the usual mistake.
| Situation | Best pick | Why |

Test on a hidden spot before cleaning anything plated, painted or glued.
By Budget
Compare yield, not bottle size, and use these tiers as relative guidance.
| Tier | Pick | What you get |
|---|---|---|
| Entry | Blitz Gem and Jewelry Cleaner Concentrate Refill, 8 oz | A small 8 oz jewelry refill. |
| Entry to mid | iSonic Jewelry and Eyeglass Cleaner Solution Concentrate | A capful-per-use jewelry and eyewear concentrate. |
| Mid | WoldoClean Ultrasonic Cleaner Solution Concentrate, 25.4 oz | 8 gallons at 1 to 40 with a broad item list. |
| Mid to premium | Tillbrook Ultrasonic Cleaner Solution, Makes 8 Gallons | An 8 gallon auto-parts concentrate. |

| Best yield | Sylvan Hills 32 oz Ultrasonic Carburetor and Parts Cleaner | Up to 50 gallons at 1 to 250. |
The best value is the liquid that matches your items, not the largest bottle.
Personal-Care Formula vs Parts Degreaser
The two families work differently and should not be swapped.
Personal-care formula
A mild, often non-toxic liquid meant for jewelry, lenses and dental items. The iSonic, Blitz and WoldoClean are in this group, with the WoldoClean also covering small parts. Choose one for rings, glasses and appliances.
Parts degreaser
A stronger concentrate meant to cut varnish, gums and carbon from metal. The Tillbrook at 8 gallons, the Qucship at 9 gallons and the Sylvan Hills at up to 50 gallons are in this group. Choose one for carburetors and engine parts, and ventilate.
Use personal-care liquids for items you wear, and degreasers only for metal parts.
By Dilution Style
How you measure affects how easy the bottle is to live with.
| Style | Pick | Best for |
|---|---|---|
| One capful per use | iSonic Jewelry and Eyeglass Cleaner Solution Concentrate | Quick jewelry cycles. |
| One capful per tank | WoldoClean Ultrasonic Cleaner Solution Concentrate, 25.4 oz | Tanks from 8 to 64 fl oz. |
| Dilute from a refill | Blitz Gem and Jewelry Cleaner Concentrate Refill, 8 oz | Jewelry refills. |
| Measured 1 to 250 mix | Sylvan Hills 32 oz Ultrasonic Carburetor and Parts Cleaner | Large tanks and frequent use. |
| Gallon concentrate | Qucship Ultrasonic Carburetor Cleaner, Makes 9 Gallons | Shop-sized tanks. |
Write the mix date on the tank so you remember to replace it.
For Jewelry and Eyeglasses Specifically
Personal items need a gentle, rinsable liquid.
Look for
A non-toxic, biodegradable formula that names jewelry or eyewear, a simple capful dose, and clear rinse directions. Avoid parts degreasers and keep soft stones out of the tub.
In this comparison
The iSonic is dosed at one capful and covers gold, silver, diamonds, watches and eyewear, the Blitz is a non-abrasive gem refill, and the WoldoClean is gentle on lens coatings with an 8 gallon yield.
Rinse and dry after every cycle so no film dulls the finish.
When to Spend More
Pay for yield or breadth only when your use justifies it.
| Spend more if | Save if |
|---|---|
| You clean glasses, dental items and parts, choose the WoldoClean at 8 gallons. | You only clean jewelry, where the Blitz 8 oz is enough. |
| You run a big tank often, choose the Sylvan Hills at up to 50 gallons. | You rebuild one carburetor a year, where a small bottle is enough. |
| You clean many engine metals, choose the Qucship with seven listed metals. | You only clean aluminum or brass, where the Sylvan Hills covers it. |
| You want a jewelry and eyewear dose, choose the iSonic at one capful. | Water alone handles your light dirt. |
A bottle you finish is better than a huge one that expires in the cupboard.
Frequently Asked Questions
Which ultrasonic cleaner solution is best for most homes?
The WoldoClean is the most versatile for a household, making 8 gallons at 1 to 40 and covering eyeglasses, dental items, razors and watch parts. If you only clean jewelry, the iSonic or Blitz is more focused. For engine parts, the Sylvan Hills, Tillbrook or Qucship fit better.
Can I use plain water instead of a solution?
Yes for light dirt, because cavitation works in plain water. A concentrate helps with oil, varnish, carbon and polish residue that the bubbles alone only loosen. Check your machine's manual first, since some makers advise water only. The iSonic and WoldoClean both suit use in a home tub.
Can I use a parts cleaner for jewelry?
No, treat them as different families. The Tillbrook, Qucship and Sylvan Hills are built to cut varnish and carbon from metal parts, and none lists jewelry or eyewear. Use a jewelry-safe liquid such as the iSonic or Blitz for rings, and keep soft stones out of any ultrasonic tub.
How much concentrate do I use per fill?
It depends on the bottle. The WoldoClean and iSonic use one capful, the Sylvan Hills mixes at 1 to 250, and the Qucship turns 1 gallon into 9. Follow the label for the exact amount, and measure carefully because a weak mix cleans poorly.
How often should I change the liquid?
Replace it when it looks visibly dirty, as the Sylvan Hills listing advises. A cloudy or dark liquid cleans less well and can leave film. For a light jewelry routine this may mean a fresh mix every few sessions, and for engine parts it can be after each heavy batch.
Do solutions remove tarnish?
Mostly no. Tarnish is a chemical change and not dirt, so a liquid in a tub cannot reverse it. The iSonic listing mentions tarnish, but treat that claim cautiously and use a silver polish for real tarnish. The solution handles oils and film.
Is it safe to use these around the house?
Personal-care formulas such as the iSonic, Blitz and WoldoClean are described as non-toxic, and the WoldoClean is ammonia free. Parts formulas are stronger, so use ventilation and gloves, and follow local disposal rules. Never mix products, and keep every bottle away from children and pets.
