Care : Caring for paintbrushes is essential to keeping them in good working condition and to their life span. Watercolours : dip the paintbrush in water and rinse in warm water. Oil : dip the paintbrush in a solvent such as taltine. Clean in soapy water and rinse in warm water. Acrylic : clean in soapy water and rinse in warm water.
