When it comes to in-depth cleaning of items, ultrasonic cleaners are the ultimate tool. They can clean jewelry, dentures, glasses, fuel injectors and tools without breaking a sweat. They are also perfect for cleaning larger stuff, like carburators and gun components.
Nowadays, ultrasonic cleaning is not just limited to professionals. Anyone can buy an ultrasonic cleaner for use at home. Why take your stuff to be professionally cleaned, when you can just as easily (and cheaper!) do it yourself?
There are many ultrasonic cleaners available on the market. In this article I will share which ones are best, and the things you need to keep in mind when buying one.
Let’s take a closer look at which ultrasonic cleaner is best for you!
What is an ultrasonic cleaner and how does it work?
Before looking at which ultrasonic cleaner to buy, let’s quickly go over what an ultrasonic cleaner is and how it works.
An ultrasonic cleaner is a tool that uses ultrasound waves to clean objects. It is used for cleaning a wide range of items, from delicate jewelry to dirty carburetors, from eyeglasses to industrial products.
The ultrasonic cleaning process works through acoustic cavitation. This is a process that creates tiny imploding bubbles on a microscopic scale. When these bubbles implode, they generate forces that create a cleaning effect.
Ultrasonic cleaners are always used in combination with a liquid cleaning solution. The liquid transfers the ultrasound waves to the surface of the object being cleaned, and also helps remove contaminants.
This article looks mostly at the best ultrasonic cleaners on the market today. If you interested in reading more about ultrasonic cleaning, I recommend reading The Ultimate Guide to Ultrasonic Cleaning. It gives more information on how to get the best results from your cleaner, explains the do’s and dont’s, and looks at which liquid cleaning solutions are best for the items that you want to clean.
What are the benefits of ultrasonic cleaners?
Let’s go over some of the benefits of ultrasonic cleaning compared to other cleaning methods.
- It can clean almost any contaminant. With the right cleaning solution, ultrasonic cleaners can remove almost any contaminant. You can use it to remove oil, dirt, fingerprint smudges, old paint, burned carbon and so on. You can do this on objects made from most metals (including jewelry made from silver, gold, platinum and brass casings), plastics, glass, ceramics and more.
There are a couple of exceptions however, and it is important to use the correct cleaning solution for the object you intent to clean. Aluminium, for example, can corrode when cleaned with the wrong solution.
- Cleans in the hardest to reach spots. The ultrasound waves in the cleaning solution reach places that you otherwise would not be able to reach by hand.
- Little time and effort required. Once you have your cleaning process dialed in, there is not much you have to do. Aside from inserting and removing objects from the ultrasonic cleaner basket and pressing a few buttons, you are free to spend your time doing whatever you want while the cleaning is done for you.
- Safe for you and for the environment. Unlike with other cleaning methods, there is no need to use harsh solvents. Not only are these damaging for the environment, but also for your skin and lungs. In addition, there is no risk of cutting yourself with sharp objects, like when manually cleaning drill bits, scalpels or other sharp instruments.
With all these benefits, a good ultrasonic cleaner easily pays for itself. You free up your time not having to clean things by hand, and you don’t have to spend money on expensive solvents. Plus you also don’t need to go out and have your stuff professionally cleaned anymore, which saves both time and money!
Best ultrasonic cleaners in 2020
Now that you know why they are so great, it is time to look at some of the best ultrasonic cleaners that are currently available. Some cleaners work better for certain purposes than others. This is because of their specific tank size, ultrasound frequency and other functionality, like heating, degassing and cleaning cycle durations.
Below I have listed what are, in my opinion, the best ultrasonic cleaners for each common cleaning job.
Your everyday household items and personal accessoires, like eyeglasses, watches and jewelry, do not get extremely filthy. They typically get dirty with skin cells, skin oils and smudges. For that reason, in order to clean these items you don’t need a fancy or large ultrasonic cleaner. You do want something that is reliable and does a proper job however.
The InvisiClean IC-2755 is an ultrasonic cleaner that does just that. It is powerful enough for all your basic cleaning needs, has a built-in fan so that it does not easily overheat, and has a solid 27oz (800ml) stainless steel tank with enough space for your typical jewelry and household objects.

When on a budget
Even on a budget it is possible to obtain a decent ultrasonic cleaner. It won’t have as much power as other, more expensive, ultrasonic cleaners, but to compensate for that you can clean your items for a longer period of time. The tank capacity also won’t be exceptional, but this is not a problem if you only plan on cleaning small items.
The Magnasonic MGUC500 is one of the most popular budget ultrasonic cleaners available, mainly for its low price and excellent value. It is good enough for simple cleaning jobs and won’t break the bank.

With medium capacity (2.6 Qt / 2.5 L)
Medium-sized items, for example handheld tools and firearm parts, need to be cleaned too, and do not fit in small ultrasonic cleaners. For these items you want an ultrasonic cleaner with a larger tank capacity. This also comes in handy if you want to clean large batches of smaller objects, without having to run the ultrasonic cleaner multiple times.
The iSonic P4820-WSB is an ultrasonic cleaner that enables you to do just that. Aside from the usual functions you would expect from a good ultrasonic cleaner, it comes with a 2.6 Qt / 2.5 L stainless steel tank in which you can clean quite a bit at once.

With large capacity (8 gal. / 30 L)
Even large items can be ultrasonically cleaned. Some examples of these are carburetors, car and bike parts, engine parts and large tools. These objects are not only large, but typically also get the most dirty. So it is important to have an ultrasonic cleaner with a large tank in addition to powerful cleaning functionality.
The DK SONIC DK-3000S ultrasonic cleaner is perfect for cleaning large, heavily contaminated objects. It has a large collection of features, making it one of the most versatile ultrasonic cleaners out there. It also allows you to clean with both 28 kHz and 40 kHz frequencies, meaning that you can use it to clean heavily soiled items (with 28 kHz) as well as more delicate parts that need more precise cleaning (40 kHz).

For commercial use
Commercial ultrasonic cleaners are often used more intensively, and for that you need an ultrasonic cleaner that is up to the task. Not only does it need to run for longer periods without overheating, but it also needs to be more durable and reliable so that it does not break down.
The iSonic P4821-BSB offers you just that. It is a durable ultrasonic cleaner that is designed with reliability in mind and can run for longer periods without cooling down. No need to worry about the unit breaking down or having unnecessary downtime.

For cleaning PCBs
Ultrasonically cleaning printed circuit boards can be a bit of a challenge. Dirt and crud comes off relatively easily, but flux and other soldering residues are harder to remove. Not only that, but larger PCBs often don’t fit in regular sized ultrasonic cleaners because of their large surface area and thin profile. Thus, for cleaning PCBs you need an ultrasonic cleaner that is both powerful and has a long, thin tank.
One of the most popular ultrasonic cleaners for cleaning PCBs that offers these features is the Crest CP500D. It is often used for cleaning larger PCBs, such as 13″, 15″ and 17″ MacBook Pro logic boards. In combination with an appropriate cleaning solution like Branson EC, you will be able to remove dirt and any trace of flux and soldering residue in one go without having to pre-rinse or brush your boards.
Of course, this ultrasonic cleaner can be used for cleaning items other than PCBs as well.

For cleaning vinyl records
Vinyl records have a tendency to get dirty. Whether it is dust, fingerprints, smudges or other debris, it finds its way onto the surface and into the grooves of the record. For many vinyl collectors, cleaning all of their dirty records by hand would be an arduous task. Luckily, ultrasonic cleaning is one of the best methods to clean records. But in order to do so, you will need a quality ultrasonic vinyl record cleaner.
The iSonic P4875II+MVR10 is one of the best ultrasonic record cleaners on the market. The machine holds up to 10 records at once, which makes it ideal for cleaning large collections. Its motorized fixture automatically rotates the records as they are being cleaned. Not only is there minimal labor involved in cleaning, but with 10 records at a time it will be finished in no-time. That way you can spend more time listening to your records, but from now on with a lot less pops, crackles and background noise.

For dentures/retainers/aligners/mouth guards
Dentures, as well as retainers, Invisalign aligners, mouth guards and night guards, can be hard to clean. They build up tartar, calculus and stains from coffee, food, tobacco, and so on. Rinsing and brushing them by hand is possible, but it is a lot of work and does not get them as clean as a professional cleaning would.
With an ultrasonic cleaner however, cleaning dentures and other dental appliances becomes a breeze. With a good cleaning powder, removing stains and disinfection can be done in one go. You don’t need anything fancy, a simple ultrasonic cleaner for dentures will do the job.
The iSonic F3900 is the ideal machine for this purpose. It is a small ultrasonic cleaner that is perfect for daily use. It works for regular-sized upper and lower dentures, partials, aligners, guards, and so on. Because of its small size it is easy to store when not in use.

For long objects
Ordinary ultrasonic cleaner tanks fit a lot of different objects, but they don’t fit everything. Long objects, like tubing, pipettes, gun barrels, AR uppers and other oddly sized items, can not be cleaned in regular sized tanks. For this, you must use an ultrasonic cleaner with a long bed.
The iSonic P4890(II) commercial ultrasonic cleaner is a great option for cleaning long objects. It is a versatile cleaner with a lot of features, the most important of which is a 25.5″ / 65 cm long tank.

Buyer’s guide – What to keep in mind when buying an ultrasonic cleaner
When deciding which ultrasonic cleaner to buy, it is important to keep in mind what type of items you plan on cleaning most often. This will dictate the features of the cleaner that is best for you, such as ultrasonic frequency, tank size and cleaning cycle duration.
Let’s review how these factors influence what ultrasonic cleaner you should buy.
One of the most important aspects in choosing an ultrasonic cleaner is the tank size, or more specifically the size of the basket in the tank. Since you can’t directly place objects on the surface of the tank, the basket is what limits the maximum size of the objects you can clean.
It is important that you can fit the biggest item you plan on cleaning inside of the basket, and that it is fully submerged when the tank is filled to its maximum fill level. Keep in mind that you shouldn’t fill the tank to the rim. Instead you should add enough cleaning solution to match the maximum fill level indicated on the inside of the tank.
In researching ultrasonic cleaners, you might have noticed that not all of them clean at the same ultrasound frequency. What frequency is best depends on what you plan on cleaning. Lower frequencies like 25 kHz work best for cleaning large flat surfaces, whereas higher ones (80 kHz and up) are more suited for delicate objects.
For most applications, at and around 40 kHz is a great option and a solid middle ground between cleaning power and precision. This is why most commercially available ultrasonic cleaners operate around the 40 kHz frequency. Unless you need to perform very specialized cleaning, this is the frequency to go for.
Most liquid ultrasonic cleaning solutions work best at temperatures of 120-150 °F (50-65 °C). So in order to get the best cleaning results, it is important that the cleaner you buy comes with a built-in heater.
The best option would be an ultrasonic cleaner with an adjustable heater that gives you direct control over the temperature of the solution. That way, you can match the temperature to the recommended temperature for the specific solution, or experiment with temperatures to see what works best.
An adjustable heater is not strictly necessary however, and any basic heater functionality is often enough.
Degassing, the removal of gases from a liquid (in this case from our cleaning solution), before cleaning is required to get good results. Without gases in the solution, more ultrasonic energy will go towards cleaning the objects in the tank.
Most higher-end ultrasonic cleaners come with a degas function that automatically degasses the solution at the press of a button. You can also do this manually however, by simply running an ultrasonic cleaner for 5 minutes (ideally with the heater on) before placing the items in the basket.
Some ultrasonic cleaners come with accessories that are particularly useful for cleaning certain types of objects. For example, the iSonic DS310C-CE comes with an accessory for cleaning makeup brushes, whereas ultrasonic vinyl record cleaners come with motorized fixtures that automatically spin records through the ultrasonic bath.
If you will be using your ultrasonic cleaner for cleaning a lot of a certain item, it can be useful to have a specialized accessory for that type of item included.
When cleaning fragile objects, it is beneficial to have an ultrasonic cleaner with a sweep mode. The sweep mode varies the ultrasonic frequency and avoids standing waves in the cleaning solution. Standing waves are responsible for dead zones, areas with minimal cavitation activity, and hot spots, areas with a lot of cavitation activity.
Hot spots can cause damage, especially when cleaning delicate items. In dead zones on the other hand, not enough gets cleaned.
If you don’t regularly clean fragile items where precise cleaning is very important, then a sweep mode is not something you will get much benefit from.
As you can see, there are many different types of ultrasonic cleaners available. If I would have to recommend one specific cleaner that works best for most things, it would be the InvisiClean IC-2755. You can’t go wrong with it if you want to clean your jewelry, eyeglasses, tools and other basic items.
You have learned:
- Which ultrasonic cleaners are best for different types of cleaning.
- What to look for when buying an ultrasonic cleaner.
