Can you put a watch in an ultrasonic cleaner? The answer is a resounding “Yes!”. The question is not whether you can, but whether it’s ethical or not. It’s not just about the time it takes to clean your watch, it’s about the environmental impact of the cleaning process. An ultrasonic cleaner uses sound waves to move debris and dirt away from the watch, but it can also damage the delicate materials used in watches. Not only does it wear down watch components, but it can also damage the watch if it comes into contact with water. It’s not a solution to your watch cleaning problem, but a hindrance to it. In my opinion, it’s important to take care of our watches and watch cleaning processes as they require the same care and attention as other valuable jewelry.
