Method 1
Preparation: an old magazine, a clean plastic wrap, an old toothbrush, and a detergent.
Operation process:
First of all, we stack the preservative film and magazines together, and then roll them together into a cylinder, which can prevent the book from getting wet when cleaning the watch strap later.
Then put the watch on the rolled cylinder, and slowly enlarge the cylinder made of magazine until the strap is fully opened, so that the watch will not fall off. On the one hand, it is convenient for cleaning, and more importantly, after opening the watch strap, the stains at the gap of the watch strap can be cleaned. Now let's clean the watch strap.
We'd better clean the surface of the watch strap first, and then clean the stains in the gaps of the watch strap. The connection of these crevices is very close, so it is difficult to clean the dirty things inside. Now these crevices are opened by the cylinder rolled by the book, and the dirt inside can be cleaned naturally. Let's clean the back of the watch strap, and also clean the stains on the surface first. Next, clean the stains in the cracks. OK, now the cleaning is done. Finally, we need to clean the watch strap with clean water. All the processes are finished, and the rest is to dry the watch strap in the shade.
Note: do not expose to the sun, it will damage the quality of watch strap.
Method 2
We put the watch strap in boiling water with detergent for about 15 minutes. The cylinder made of books can't support the gap at the joint. And put in hot water is the use of the principle of thermal expansion and cold contraction, so that the gap at the junction of their own expansion, so you can clean. 15 minutes later, let's start to clean the watch strap. After cleaning, let's look at the water. It's dirty enough. It means the watch strap is cleaned. Next, let's soak the watch strap in cold water for about 15 minutes. The purpose is: first, soak the detergent on the watch strap clean; Second, the same is the use of the principle of thermal expansion and cold contraction, so that the watch band up to open the gap to restore the original. When it's time, take out the strap and dry it in the shade.
