How to deal with bamboo chopsticks without mildew

I don't think bamboo chopsticks will be moldy when treated like this:

1. Keep dry: clean it in time after use, and dry it thoroughly after cleaning to avoid humid environment.

2. Regular disinfection: it can be disinfected with boiling water.

3. Hot water boiling: put it in a boiling water pot for 30 minutes, and it can remain relatively moldy after drying.
