This guide will teach you the best methods, products, and tips for keeping your brushes clean and ready for your next session.

• Drying: Lay brushes flat or suspend them tip-down to prevent water from entering the ferrule.

Special Care for Different Brush Types

• Bristle Brushes: Clean with hot water and reshape after washing. Avoid excessive pressure while painting.
• Sable Brushes: Use conditioner periodically and store away from sunlight.
• Synthetic Brushes: Clean thoroughly and avoid exposing them to harsh chemicals.

Avoiding Harmful Substances

Certain products can damage your brushes:

• Avoid: Hand soaps with abrasives (e.g., walnut particles), dish soaps with strong surfactants, and baby oil.
• Clove Oil: Although useful for slowing drying times, it is expensive and impractical for regular use.
• Pigment Residue: Always remove pigment thoroughly to prevent buildup and future painting issues.

Repurposing Old Brushes

If your brushes become frayed, don’t toss them out. Use them for texture, splatter, or experimental painting. You can restore sharpness by dipping them in gum Arabic or reshaping with Vaseline.
