Top 12 Best Ultrasonic Cleaners (For Your Watch)

Ultrasonic jewelry cleaners, also known as ultrasonic watch cleaners (depending on the purpose you use them for) are the best and most effective cleaning tools for your watch. But the fact is that ultrasonic cleaners do not only work for watches, but also a wide array of other products. So if you are reading this and are not looking to clean your watch, this guide also applies to you.

Over time, your watch will accumulate a lot of dirt and grime. Primarily, this includes sweat, dead skin, hair, and fat from your skin, but it also includes dust and other types of dirt. A nice watch+ dirt is not a combination we like to see together. And there are many reasons for this.

First off, if you don’t clean your watch, dirt will accumulate and built up – in particular on the metal bracelet. Not only is this really nasty (and the truth is, we have seen a lot of nasty watches over the years which have never been cleaned. As an example, look at the one below:

When your watch is dirty, it loses its original luster and shine. This is obviously not something you want to happen with your watch. You want it to look as good as possible.

Furthermore, having a dirty watch is unhygienic. When you don’t clean your watch, dirt, bacteria, and other grime build up on your watch. In a way, your watch is an extension of your hand. Just imagine not washing your hands for a few weeks.

But maybe most important is that when you have a lot of dirt and grime on your watch, you speed up the aging process, in particular on the metal bracelet. Dirt can lead to rust and tarnishing, but it will also lead to premature wear in the bracelet as it first finds its way between the links, screws, and pins, and work like sandpaper by increasing the friction between the links and other moving parts such as the clasp. As a result, the moving parts will be worn out much faster compared to when you are cleaning it. With that said, it is very important that you clean your watch on a regular basis in order to keep its luster, but also to keep it in good condition for as long as possible and minimize aging and wear.

The main accumulator of dirt on your watch is your metal band. This has a lot of creaks and places where dirt will stay and then accumulate over time if you don’t clean it. 

If nothing else, rinsing your watch with water helps remove dirt. You can also scrub it with a brush. This will remove dirt and prevent build-up. The catch is that using this method, it can be difficult to access all places and remove all the dirt that has accumulated. As such, the single most effective way to thoroughly clean your watch is by using an ultrasonic cleaner.

This is the ultimate way to clean your watch, and also the method that watchmakers, jewelers, and professionals use. Not only is it extremely easy, but it is also very effective. Having an ultrasonic jewelry cleaner thus means having access to a professional cleaning tool from the convenience of your home. It ensures that the watch you are going to clean truly gets clean down to the core and its smallest, most hidden areas.

What is an ultrasonic cleaner?

An ultrasonic jewelry cleaner is a tool for cleaning your watch using ultrasound (usually from 20–40 kHz) to agitate a fluid in order to clean an item.

The ultrasonic cleaner creates ultrasound waves, and the vibrations cause cavitation, where tiny bubbles form and burst. When the tiny bubbles burst, they create a pressure that “knocks” off the dirt from the watch. This movement of the water helps remove and dissolve the dirt, leaving your item clean.

Is it safe to put a watch in an ultrasonic cleaner?

It is not advised to place your whole watch inside an ultrasonic cleaner. If you are going to clean your watch, it is therefore advised that you remove the bracelet and only clean this using the ultrasonic cleaner. The case of the watch can in turn be cleaned using a soft brush. Whilst it is possible to put many watches in an ultrasonic jewelry cleaner, it is not advised.

It is, however, a different story if the watch and movement are completely disassembled. In that case, ultrasonic cleaners are the tools that watchmakers use when servicing a watch. After disassembly, the watch parts are cleaned in an ultrasonic jewelry cleaner, before they are assembled again.

The issue with putting your whole watch in an ultrasonic cleaner, even if it is water-proof is that the vibrations and effect of the ultrasonic cleaner can cause damage to the movement but also cause premature wear on things like the rubber gaskets that are meant to keep the watch protected against water. The ultrasonic waves that are used in a cleaner are not good for the movement.

How to clean your watch in an ultrasonic cleaner

Cleaning your watch in an ultrasonic cleaner is easy and very straightforward. If you want to clean your bracelet, begin by removing the bracelet from the case. To increase the efficiency of the cleaning, open the clasp so that all areas are exposed. Fill the ultrasonic cleaner container with water (lukewarm or warm). If you want, you can add soap for a better effect.

Now, place the bracelet inside the container and close the lid. If you want to clean a disassembled watch, add those parts to the container as well. In the settings, you can choose for how long you want the program to run. For watch bracelets, it is generally enough with a few minutes, but you can start by running a program of a few minutes, and then inspect the bracelet when it is done. If you are satisfied with the result, rinse it, and wipe it off. If there is still dirt left, clean it for a few more minutes.

What fluid goes in an ultrasonic cleaner?

Although you can use regular water in an ultrasonic (and most people do) the best is to use deionised water. This will improve the result since deonised water is a natural solvent that doesn’t contain impurities and salt that regular water does. Regular water may leave stains from this type of impurities on the watch after it has been washed.

But regardless of what fluid you use, it’s still always advised to rinse the object afterwards to get rid of dirt and other things that will affect its luster.

Is ultrasonic cleaning safe for diamonds?

It is generally not advised to use an ultrasonic cleaner for diamonds. Whilst, for the most part, it won’t be an issue, it can subject the diamond to a risk as the ultrasonic cleaning may increase its internal flaws. This is particularly true for diamonds with a lot of inclusions.

Some colored gemstones are recommended in particular to not have in an ultrasonic cleaner. It is especially important to not put emerals in ultrasonic cleaners as this gemstone is oiled and often has inclusions. It is therefore best to clean most gemstones with a brush and soapy water.

How should you leave jewelry and watches in ultrasonic cleaner?

The time you need to have your ultrasonic cleaner activated mainly depends on how dirty the item. In general, objects that aren’t very dirty will get a good result after just one or two minutes. But extremely dirty objects may need to be in the washer for 10 to 20 minutes. You can pause the ultrasonic cleaner mid-way and evaluate the result.
