How to Clean a Paint Palette. As much as you may try to keep your palette clean, it's easy to forget occasionally and end up with a palette covered in rock hard dried oil paints. Dried oil paint is never easy to clean, but with some turpentine and a razor blade you can get it back to a usable state again.
Things You'll Need
Wipe the palette clean after each painting session to prevent oil paint from crusting onto the palette in the first place. You can use some turpentine or linseed oil and a rag to remove all paint residue.
Start with a well ventilated room. Open windows in the room and set up a window fan, if you have one. Breathing in turpentine fumes is hazardous to your health.
Wipe up any excess paint that hasn't yet dried onto the palette.
Use a clean rag to dab turpentine onto the dried oil paint.
Allow the turpentine to soak into the dried oil paint for about 30 minutes.
Scrape the softened dried paint off the palette with a razor blade.
Consider using disposable palettes, if you find that you often forget to clean up well after a painting session. Cheap plastic palettes can be purchased from craft stores, or you can cover a wooden palette with plastic wrap. You could also try a pad of palette paper.
Soak a paint palette covered in dried acrylic paint in fabric softener. The paint will soften and come off very easily.
