Yes! In the cleaning supply aisle in the grocery store is Mr. Clean Magic Eraser. The original works best. Wet the sponge – you can cut it into small cubes – and lift out paint that is dried and unwanted in your painting. You can almost get it back to white paper. This works better than a scrubby bristle brush but of course it can’t be used in tiny spaces like a brush. It will take off most anything. After a few uses, the sponge crumbles and needs to be tossed.
