B. The outer surface can be disinfected by spraying with 3 ml of medical alcohol, and it can be used again after drying;

C. Soak it in 84 disinfectant solution (diluted at 1:99) for 20 minutes, or other disinfectant solution (please strictly follow the instruction in respect of ratio on Fabrics sterilization, for example, if it reads dilution rate 1: 20 for fabrics, it means you need to put 10ml disinfectant liquid with 200ml clean water), rinse it with clean water to tasteless, and can be used again after drying (no disinfectant residue).

Do not rub or scrub the mask during cleaning/sterilizing. 

Note: No any residue of disinfectant or soap liquid is allowed to be remained on the face mask, which will cause reduction of filtering efficiency.
