Cleaning water-based paintbrushes before the paint dries
For latex or water-based acrylic paint, remove excess paint before it hardens, then use water and a little mild soap. Solvent-based paints need different treatment.
Sherwin-Williams distinguishes water-cleanable latex/acrylic paints from oil-based coatings that require approved solvents. Its brush-cleaning guide prioritizes removing wet paint, mild soap as needed, thorough rinsing, and complete drying before storage. Check local rules for paint waste and rinse water.
