 Hello, I'm Ojitang. Today I'd like to demonstrate how to revitalize a mask. You need an electric rice cooker, worn surgical masks, and a cloth. Open the cooker and place the mask flat in the elevated inner pot. Do not add water. Close the lid. Turn on the cooker. Wait for 8 minutes. Open the lid and let the pot cool. Voila! The mask is revitalized. Taiwan can help.
