What is an effective method for cleaning paintbrushes after use?

Using turpentine followed by rinsing with warm water is an effective method for cleaning paintbrushes after use, particularly if the brushes have been used with oil-based paints. Turpentine is a solvent that effectively dissolves oil and paint residues, allowing the paint to be easily removed from the bristles. After using turpentine, rinsing the brushes with warm water helps to further clean out any remaining solvent and paint particles, ensuring that the bristles are fully clean and do not become hardened or mis-shaped.

The use of soap only is less effective for ensuring all paint residue is removed, especially with oil-based paints, as soap alone may not dissolve the paint adequately. Cold water only does not provide the necessary emulsification or dissolution of paint, particularly with oil paints, making it ineffective for thorough cleaning. Relying on paint thinner directly can be harsh on the brush bristles, potentially leading to damage over time, and it may not fully clean the brushes as efficiently as the method involving turpentine followed by warm water.
