A wristwatch, also known as a wristwatch, refers to an instrument worn on the wrist for timing and displaying time. Watches are usually watchbands made of leather, rubber, nylon cloth, stainless steel and other materials; the most common watchband is made of metal materials, the metal watchband has a plurality of pores, sweat, grease secreted by a human body and dust in the environment easily enter the pores in the daily use process, and if the watchband is not cleaned for a long time, the watchband is embrittled, rusted and the like, so that the watch needs to be cleaned frequently.
One of the currently common cleaning methods is to use ultrasonic waves to clean, specifically, place the watch in a container containing a solution (clear water or a cleaning agent) and apply ultrasonic waves to achieve the purpose of cleaning. However, the use of ultrasonic waves can increase the mechanical gap in the watch, which affects the precision and accuracy of the watch. Another common method is to directly use a mechanical cleaning method, such as a toothbrush, etc., to brush the gaps of the watchband after dipping detergent, but this cleaning method is time-consuming and labor-consuming, and the hidden watchband gaps are not easy to clean. In addition, some people wash the watchband after completely decomposing the watchband, which is a very complicated process. To solve these problems, chinese application 201310054628.5 discloses a full-automatic watch washing machine, which includes a pre-washing, rinsing and drying module to wash the watch in all directions, however, the washing machine is costly and cannot achieve the effect of washing the watch through simple mechanical washing. Therefore, the physical cleaning methods such as ultrasonic wave and toothbrush are poor in effect and low in efficiency.
In order to improve the cleaning effect of the watch, the cleaning agent is improved in a feasible way. Chinese patent application 201310547446.1 discloses a copper alloy low-temperature cleaning agent, which is prepared from dodecylbenzene sulfonic acid, coconut oil acid diacetic acid amide, fatty acid polyoxyethylene ether, citric acid, oleic acid, preservative, water and the like, is especially suitable for copper alloy, and can clean watches at room temperature; however, this cleaning agent contains a large amount of surfactant, and after cleaning, a large amount of rinsing work is often required, which is troublesome.
