Never use an ultrasonic cleaner to clean the watch head. Watch parts such as straps and bracelets can be cleaned in an ultrasonic cleaner. Some gemstones and types of jewelry are not meant to be cleaned with an ultrasonic cleaner, these are listed in the next section with exceptions. Jewelry that can be cleaned in an ultrasonic cleaner is made from gold, silver and platinum, and includes gemstones like diamonds, sapphire and rubies. Ultrasonic cleaners are ideal to clean rings, bracelets, necklaces and earrings. First I will list common items that you can clean with an ultrasonic cleaner.

There are a few exceptions however, which I will talk more about later. Most hard, non-absorbent materials (like plastic, metal, glass and ceramic) are suitable. It is possible to clean a wide range of objects and materials in an ultrasonic cleaner. What can you clean in an ultrasonic cleaner? In addition, there is no need to work with aggressive solvents that are likely hazardous to your health.

Unlike with manual cleaning, there is no risk of cuts or injuries when cleaning drill bits, scalpels or other sharp instruments when using an ultrasonic cleaner. Because ultrasonic cleaning is easy to learn, easy to do and does not involve a lot of additional time for maintenance, it is very cost-efficient. Ultrasonic cleaners are relatively simple devices and do not require a lot of maintenance. While an ultrasonic cleaning cycle can take a while depending on the object being cleaned (usually from about 2 up to 20 minutes), you can simply set up the machine and then do something else.

It does not take a lot of time or effort to learn how to use an ultrasonic cleaner. Assuming that the cleaner is big enough, you can add additional parts to the tank and clean them without any extra effort. This makes it particularly useful for cleaning things like fuel injectors, carburetors and other complex parts. With an ultrasonic cleaner, you are not only able to clean exposed surfaces, but also the more hard-to-reach and even hidden areas. This makes ultrasonic cleaners great for cleaning jewelry, watch components or other delicate objects. While the cleaning is thorough, it is also fairly gentle and is unlikely to cause damage.

After a full cleaning cycle with the right cleaning liquid, objects can come out looking like new. Ultrasonic cleaning removes down to the smallest dirt and particulates.

Some examples of contaminants are grease, oil, dirt, dust, rust, pigment, lime scale, flux, burned on carbon, fingerprint oils and polishing compounds. There are few limits to the contaminants an ultrasonic cleaner can clean and remove. Let’s look at the benefits in more detail. Most notably, ultrasonic cleaning is thorough, fast, efficient and last but not least, anyone can do it. It has many benefits, especially compared to cleaning by hand. You might be wondering why ultrasonic cleaning is one of the best cleaning methods.

What are the benefits of ultrasonic cleaning? With the right cleaning solution, this is a very effective cleaning method. Grease, rust, flux and other contaminants break apart and flow into the liquid. The accumulative effect of the millions of imploding bubbles is what causes the cleaning effect of ultrasonic cleaning. The ultrasonic waves cause these miniscule bubbles to collapse, which in turn generates high temperatures (up to 5000 ☌) and enormous forces in the liquid.īecause this all happens on a small scale and because the bubbles’ expand and collapse cycle is extremely short, the liquid only becomes mildly warm instead of absurdly hot. This is an effect known as acoustic cavitation. How does ultrasonic cleaning work?Īs the ultrasound (usually 25-42 kHz) waves pass through the liquid in the ultrasonic cleaner, many microscopic vacuum-filled bubbles rapidly expand and collapse. For the best results a specialized solution is added to the ultrasonic cleaner, but plain water with an added detergent often gives good results as well. Because it is thorough but non-abrasive, it is often used to do the final cleaning of fragile components. Ultrasonic cleaning is a method of cleaning that uses ultrasound and a liquid to clean objects. 14 Conclusion What is ultrasonic cleaning?
