How to Care for Natural-Hair Watercolour Brushes

Natural-hair watercolour brushes can last a long time with suitable care, but every brush type and manufacturer may have specific instructions. Avoid broad comparisons about the lifespan of watercolour, acrylic, or oil brushes; wear depends on the brush, medium, use, and maintenance.

Care for watercolour brushes

• Rinse paint out promptly with clean, cool-to-lukewarm water after use.
• Do not leave a brush standing in water or bristles-down in a jar.
• Use a suitable brush soap only when needed and when the maker’s guidance permits it; rinse all residue out thoroughly.
• Gently reshape the damp bristles, then dry the brush flat or with the bristles unsupported and not touching a surface.
• Store brushes only when fully dry, in a clean breathable wrap or case rather than a sealed damp container.

When a brush loses its point

A frayed brush will not always return to its original shape. Do not assume ordinary hair conditioner is suitable or restorative: it can leave residue unless the brush maker specifically recommends it. Start with thorough rinsing and the manufacturer’s care guidance; replace a brush that remains split, damaged, or unable to perform its intended task.
