Dried paint transforms quality brushes into stiff, useless tools. This cleaner reverses that damage. Winsor & Newton's formula penetrates hardened oil and acrylic paint, breaking down pigment deposits that water alone can't touch while remaining gentle enough for both natural hair and synthetic filaments. The solution works without harsh solvents that can swell ferrules or dissolve adhesives holding bristles in place.

Water-soluble and biodegradable, it cleans without leaving oily residue that would compromise future paint application. Low vapor emission means you can work in normal studio ventilation without overwhelming fumes. Non-flammable formulation eliminates fire hazards associated with traditional mineral spirits. Pour a small amount into a jar, work the brush against the bottom to release embedded paint, then rinse with water. For neglected brushes with severe buildup, leave them soaking overnight, the formula continues working to restore flexibility.

Available in 120ml bottles for occasional maintenance and 474ml sizes for studios managing multiple brushes. Regular use extends brush life significantly, protecting your investment in quality tools.
