For removal you can for instance use Grimas Cleansing Cream, Afschmink, Make-up Remover or Multi Remover Pure.
CLEARING UP THE MATERIALS
Store the make-up in a dry and cool place until the next time you use it.
The sponges are disposable so you can throw them away after use. If you do want to reuse them, first rinse them under the tap with some soap or shampoo or wash them in the washing machine (in a net bag or pillow case), set to at least 60°C.
