You can remove the Camouflage with Grimas Cleansing Cream, Multi Remover Pure or Make-up Remover. Cleanse the skin afterwards with Grimas Cleansing Lotion.
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.
You can clean brushes with water and soap or shampoo. The Powder and Blusher Brush is cleaned like this too. 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.
