First put the walnuts into clean water and moisten them so that no water drips. Then put them in a sealed bag and seal them for one hour. After the time is up, you can clean the walnuts one by one with a homemade tool. The convex surface can be cleaned with the 2-wide end of the tool. The concave surface can be cleaned with a homemade tool according to the actual situation. Use a toothbrush while cleaning. This is very easy. Just clean it up. If you encounter a stubborn or dark area (excluding the vaginal skin), you can also use a homemade tool to gently scrape it, but be sure to pay attention to the strength of your hands, and then use a toothbrush dipped in 70% Brush with alcohol and the effect is very obvious. After such cleaning, there should be no problem with normal walnuts, and you can start playing with them directly.

Note:

1. If we really can’t make a tool, we can also use a needle instead. First use a needle to pick out the dirt, and then use a brush to brush it several times. The effect is the same. Same.

2. Don’t play with the walnuts that have just been cleaned immediately. They need to be dried in the shade (they will crack if not dried in the shade). The specific method is to wrap the walnuts with toilet paper, then wrap them in a plastic bag and put them away. In a ventilated place without sunlight, it can usually be dried in the shade in about a week.
