If you have acne prone skin, we recommend using a clean cloth every day if possible.
If not, then wash the cloths every other or every third day in a 40 degree machine wash with a mild detergent. In between washes rinse the cloth well in hot water and air dry.
An alternative solution to machine washing is to soak the cloths in hot water adding a drop of white wine vinegar and bicarbonate of soda, then hang to air dry.
Additional cloths can be purchased here.
