Crème Make-up Pure is based on waxes and oils and can therefore not be removed with water. For removal you can for instance use Grimas Cleansing Cream, Afschmink, Make-up Remover or Multi Remover Pure. Then you remove the last residues with Cleansing Lotion.
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.
You can clean brushes with water and soap or shampoo. Put the moist hairs of the brushes back into shape by hand after washing. Dry the brushes lying flat on a towel and do not place them upright, since that causes the moisture to run down into the shaft.
