Hair: Black goat Care: Caring for paintbrushes is essential to keeping them in good working condition and to their life span. Watercolour: Rinse paintbrushes with water. Oil: Dip the paintbrush in a solvent such as taltine. Clean in soapy water and rinse in warm water. Solvents are not recommended for use with synthetic brushes. Acrylic: Clean in soapy water and rinse in warm water. Practical information: Never let paintbrushes dry before cleaning. Using a hydrating paintbrush cleaner after using taltine or soap prevents bristles from drying and keeps the supple shape of the paintbrush.
