How to clean stains on rubber?

Many people have the habit of wearing watches in their daily life. Currently, rubber watches are the most popular. Generally, silicone products are non-toxic, relatively resistant to high temperatures, and easy to maintain. Therefore, they are the best material for making watch straps. After wearing a watch for a whole day, especially in summer, if you like to sweat, the watch strap may be full of sweat smell. The air permeability of rubber watch straps is not very good, so how to clean the stains on rubber?

Operation process: First, we stack the plastic wrap and magazines together, and then roll them into a cylinder. This can prevent the book from getting wet when cleaning the strap later. The watch is then worn on this rolled cylinder. Slowly expand the cylinder rolled up with magazines until the watch strap is fully stretched and the watch will not fall off. On the one hand, this is for the convenience of cleaning later, and more importantly, after stretching the strap, the stains in the gaps of the strap can be cleaned. Now let's clean the strap. We should clean the surface of the strap first, and then clean the stains in the gaps of the strap. These gaps are tightly connected, so it is difficult to clean the dirt inside. Now that these gaps have been stretched open by the cylinder made of books, the dirt inside can naturally be cleaned out.

We soak the watch strap in boiling water with detergent for about 15 minutes. Why do we do this? Because the connection between the buckles on this watch strap is very tight, and the gap at the connection cannot be stretched open by rolling a book into a cylinder. Putting it in hot water utilizes the principle of thermal expansion and contraction, allowing the gaps at the joints to expand on their own, so that it can be cleaned. 15 minutes have passed, and we start to clean the strap! After cleaning, let's look at the water, it's dirty enough! This shows that the strap is clean! Next, we soak the strap in cold water for about 15 minutes. The purpose of this is, first, to wash away the detergent on the strap; second, also using the principle of thermal expansion and contraction, to restore the gaps in the strap to their original state. When the time is up, take out the watch strap and dry it in the shade.
