You can lightly wash the skin with lukewarm water and soap (or shampoo) to already remove a great part. Scrubbing too much with water and soap or shampoo can irritate the skin. You can clean the skin further if required with a cleansing milk or cleansing cream. Massage it in gently and remove it with a soft tissue.
Do not use Afschmink, as this contains waxes and oils which actually adhere the Water Make-up to the skin. Do not use ready-to-use cleansing cloths.
