Whether the watch can be cleaned with a small ultrasonic cleaning machine and whether it can be cleaned; Many people have doubts about whether they will damage their watches. First of all, it can be determined that small ultrasonic cleaning machine can be used to clean watches, and the cleaning effect is very good.

而谈到清洗效果还是得从超声波清洗原理讲起：超声波清洗机是以超出人类听觉声频的声波在液体中传导，当声波通过清洗溶液传播时，由于声波是一种纵波，纵波推动介质的作用会使液体中的压力发生变化而产生无数微小真空气泡。

When it comes to the cleaning effect, we have to start from the principle of ultrasonic cleaning: the ultrasonic cleaning machine is conducted in the liquid with sound waves that exceed the human auditory sound frequency. When the sound wave propagates through the cleaning solution, because the sound wave is a longitudinal wave, the longitudinal wave will change the pressure in the liquid and produce countless tiny vacuum bubbles.

当气泡受压爆破时会产生强大的冲击能，将藏匿于隙缝死角内的污垢打散，从而增强清洗的洗净效果，由于超声波频率高波长短、穿透力强，因此对于有隐秘隙缝或结构复杂的清洗物件，可以达到理想的洗净效果。所以说，生活中使用小型超声波清洗机清洗手表是比我们人工清洗还干净的，因为超声波的作用能使清洗溶液到达人难以清洗到的角落进行超声波振荡清洗。

When the bubble explodes under pressure, it will produce strong impact energy to disperse the dirt hidden in the dead corner of the gap, so as to enhance the cleaning effect. Due to the high ultrasonic frequency, long and short wave length and strong penetration, the ideal cleaning effect can be achieved for the cleaning objects with hidden gaps or complex structures. Therefore, the use of small ultrasonic cleaning machine to clean watches in life is cleaner than our manual cleaning, because the role of ultrasonic can make the cleaning solution reach the corner that is difficult to clean for ultrasonic oscillation cleaning.

现在市场上用来清洗手表的超声波清洗机一般都是家用型的超声波清洗机，机械手表钢带或者我们平时清洗的一些金银首饰本身是有一定的硬度的，家用系列的清洗机器普遍功率较小，频率一般均为40KHz，对于这些物件的表面是不会有任何划伤损伤的。

At present, the ultrasonic cleaning machines used to clean watches on the market are generally household ultrasonic cleaning machines. The steel belt of mechanical watches or some gold and silver jewelry we usually clean have a certain hardness. The cleaning machines of household series generally have low power and the frequency is generally 40KHz. There will be no scratch on the surface of these objects.

清洗手表一般是清洗其手表链，在清洗手表的时候，我们将手表的表盘正面朝上，让手表链浸入到水中，并且加入一定量的清洗液进行清洗，所以可以放心，全自动超声波清洗机对手表内部也不会造成损坏。

Cleaning a watch is generally to clean its hand chain. When cleaning a watch, we put the dial of the watch face up, immerse the watch chain in water, and add a certain amount of cleaning fluid for cleaning. Therefore, we can rest assured that the automatic ultrasonic cleaning machine will not cause damage to the interior of the watch.
