Disinfecting wooden chopping boards with high-concentration salt water can really play a certain disinfection role, because high-concentration salt will destroy the living environment of many microorganisms (including some bacteria and molds), making them dry and inactive.

However, this method cannot guarantee that 100% can kill all bacteria and molds. Because some microorganisms can survive in high salt environment, such as halophytes, some salt-tolerant bacteria and salt-tolerant molds. In addition, salt water may not completely penetrate into the gaps and holes of the wooden chopping board, which may hide microorganisms.

Therefore, although salt water can be used as a method to clean the chopping block, it cannot completely replace other disinfection methods. If you want to clean the wooden chopping block, you can also try the following methods:

Warm water and detergent: Cleaning the chopping block with warm water and detergent can remove oil stains and some bacteria on the surface.

White vinegar: White vinegar has a certain bactericidal effect and can be wiped on the chopping board with mixed water.

Food-grade sodium hydroxide: a special cleaning disinfectant for chopping boards, which generally contains food-grade sodium hydroxide and can effectively kill bacteria.

Regular replacement: In any case, it is difficult to completely remove deep bacteria and mold after a period of use, so it is also a good choice to replace the chopping board regularly.

I hope I can help you.
