The washcloth can be used wet or dry, depending on personal preference and purpose of use.
If you want to thoroughly clean your face, it is recommended to wet the washcloth first, then apply proper amount of facial cleanser or cleanser on it, gently massage the face, and finally rinse it with water. This can better remove the dirt and oil on the face and make the skin more refreshing.
If you just need to wipe your face, you can use the washcloth dry. At this time, you can choose some soft washcloths to avoid friction and irritation to the skin.
Whether wet or dry, wash and dry the face towel in time after use to avoid bacteria breeding. It is recommended to change the washcloth once a week to keep it clean.
