(The image with the black cap reflects newer packaging) Optimist Mixable Color is waterproof, so it can be tricky to remove from surfaces and brushes if it dries. That's why we created Optimist Ink Solvent, a gentle solvent that breaks the chemical bonds in wet or dry shellac.

Squeeze Optimist Ink Solvent onto your palette and brushes after a painting session, and our shellac-based ink will quickly start to break up and peel away. Rinse brushes after using Ink Solvent for best results.

Optimist Ink Solvent is packaged in a 200 mL Precision Bottle. Squeeze the bottle to dispense a controlled flow.
