Mr. Clean Magic Eraser sold in cleaning aisles of grocery stores can help blot out, pick up, and clean up watercolor paint. Some of the big online art supply stores sell their version but it is the same substance. It is an amazing tool to help with watercolor boo boos.
Happy Painting!
Thanks for the tip! This sounds great – how effective are they at moving water colour paint from a piece of canvas? Will the mistake be entirely invisible after using the magic eraser?
Don’t know about canvas. But even on paper, you can’t get it to pure white again. There will be a slight stain- still allows you to paint over though.
