How to clean acrylic paint brushes?

Caring for Acrylic Brushes

Proper care for an acrylic brush shares some similarities with caring for a watercolour brush, though there are notable differences. Solvent-based varnishes should be removed using Winsor & Newton Artists’ White Spirit, whereas water-based varnishes can be cleaned with soap and water. Cleaning your acrylic brush with mild soap and cool water is essential. For a thorough clean, soak the brush overnight in Winsor & Newton Brush Cleaner to remove any dried acrylic colour. Repeat the washing and rinsing process until the water runs clear.

Cleaning Acrylic Brushes

1. Initial Cleaning: Wipe the brush clean on a lint-free rag and rinse under running water.
2. Soaping: Clean the brush with cool water and mild soap, gently swirling the soapy brush in the palm of your hand.
3. Rinsing: Repeat the washing and rinsing process until the soap and water run clear. Be thorough, especially at the base of the brush head.
4. Handling Stains: Some pigments may slightly stain the brush, but this does not affect its performance or lifespan.
5. Drying: Gently reshape the brush head and remove excess water. Dry the handle and ferrule, then stand the brush head-up to allow it to dry fully.

What to Avoid

The most crucial aspect of acrylic brush care is not letting the paint dry on the brush. Dried acrylic paint is not soluble and will create a plastic-like texture. Always wash your brushes immediately after use. If you cannot wash them right away, keep them in water during your painting session.
