4 Cons Of Cleaning Paint Brushes With Acetone

Due to the powerful composition of acetone, it can dry out brush bristles and potentially damage natural hair bristles over time. It’s advisable to use this method sparingly and only on brushes with synthetics and not human hair bristles.
3. Limited compatibility
Acetone may not be suitable for cleaning all types of paint. Water-based paints, but watercolour paints should not be cleaned with acetone, as it can damage the paint and bristles.
