Chemical disinfection: you can buy special disinfectants and disinfectants, add appropriate disinfectants to warm water, put them in a towel, soak them for about 10-20 minutes, then wash them with clean water and dry them before use.

High-temperature disinfection: it is recommended to use a pressure cooker, which is relatively clean and has no oil stains. Put the towel into the pot, add water until the towel is uncovered, add a little salt, and cook over high heat. Turn off the fire after feeling that the water boils for a few minutes, continue to boil for 15 minutes, and then wait until it is cool before drying.
