*Soak in boiling water for 5 minutes
First, boil a pot of boiling water. After boiling, pour it into a basin with a mask. If it is a Plastic basin, it is recommended to dry the boiling water first, and then soak the mask. If there is a ceramic basin, it is recommended to soak it. Clean the ceramic basin, put it in the mouth cover and pour boiling water for 5 minutes.
You can rub the mask gently with soap, washing powder, etc. Rub the dusty areas well. If the force is too large, the fabric of the mask will become loose, reducing the dustproof function. So don't use too much force.
After washing with soap, the mask is then rinsed away. Rinse the soap liquid and washing powder from the mask. Just like clothes, wash it and dry it in a sunny place with good ventilation. Must be well under the sun, so as to better disinfect and sterilize.
