Hand wash your reusable face wipe after each use with warm soapy water. If your face wipe is covered in heavier pigmented makeup, you can rub two face wipes together under warm soapy water then pop them in the wash bag provided and into the washing machine with similar colours. You can also try washing the reusable face wipes at a higher heat with white stain remover powder to help with pigmented makeup stains. Ultimately we cannot guarantee no staining as all makeup differs but this won't change the efficiency of the product.
