How can paint and marker pen stains be removed?
Use a proprietary alkaline or solvent paint stripper after first testing it on a stainless steel sample or a low visibility area to make sure that it does not cause surface discoloration. Use a soft, bristle brush that will not scratch the surface to loosen the paint or marker pen residue. Permanent marker pen stains may require repeated applications of paint stripper. They can be very difficult to remove from rough surfaces. A 200 mesh or finer calcium carbonate cleaning product may help to remove the final remnants of the stain. (See the standard cleaning sections.) In the worst cases, light refinishing may be necessary.
