How to clean lunch boxes

It is best to use a dish towel instead of detergent to clean the lunch box. When the food is not too greasy, it can be washed directly with warm water. There will be many dead corners in the lunch box, which is inconvenient to clean, and improper cleaning of detergent will leave residues, which will do great harm to the body.
