Primacolor Liquid gouache is easy to clean off skin with soap and water. Washing with water enables the removal of all of the binder (dextrins: sugar polymers), which is soluble in water. However, the pigments present in the gouache may have varying affinities according to the surfaces (textile fibres, ...). These colorants can then bind to the fabric almost permanently. In the case of stains on textiles, immediately wash the surface in hot water with soap. Repeat the operation if necessary until the stain has completely disappeared. For tougher stains, using bleach-based or active oxygen-based textile stain removers can be successful as long as their use is compatible with the garment in question. It is also recommended to use protective aprons for works with children. Keep away from wallpaper, painted walls, untreated wood,... and other materials that cannot be washed.
