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.

而談到清洗效果還是得從超聲波清洗原理講起：超聲波清洗機是以超出人類聽覺聲頻的聲波在液體中傳導，當聲波通過清洗溶液傳播時，由于聲波是一種縱波，縱波推動介質的作用會使液體中的壓力發(fā)生變化而產生無數(shù)微小真空氣泡。

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.

當氣泡受壓爆破時會產生強大的沖擊能，將藏匿于隙縫死角內的污垢打散，從而增強清洗的洗凈效果，由于超聲波頻率高波長短、穿透力強，因此對于有隱秘隙縫或結構復雜的清洗物件，可以達到理想的洗凈效果。所以說，生活中使用小型超聲波清洗機清洗手表是比我們人工清洗還干凈的，因為超聲波的作用能使清洗溶液到達人難以清洗到的角落進行超聲波振蕩清洗。

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.

現(xiàn)在市場上用來清洗手表的超聲波清洗機一般都是家用型的超聲波清洗機，機械手表鋼帶或者我們平時清洗的一些金銀首飾本身是有一定的硬度的，家用系列的清洗機器普遍功率較小，頻率一般均為40KHz，對于這些物件的表面是不會有任何劃傷損傷的。

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鏈，在清洗手表的時候，我們將手表的表盤正面朝上，讓手表鏈浸入到水中，并且加入一定量的清洗液進行清洗，所以可以放心，全自動超聲波清洗機對手表內部也不會造成損壞。

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.
