Wet a melamine foam pad and wring out the extra water. Magic Erasers are made by Mr. Clean and Easy Erasing Pads are made by Scotch-Brite. They are made of a foam that acts as a super-fine sandpaper that can clean many stains such as paint, marker and crayon.
Scrub the paint pen stain with the Magic Eraser or Easy Erasing Pad. If the eraser cannot fully remove the stain, move on to Step 3.
Apply rubbing alcohol to a soft cotton cloth and rub the paint pen stain with a circular motion. Press down hard to allow the fibers of the cloth to rub the alcohol into the paint.
Wash the area with some water and assess the stain; if it is still there, move on to Step 5.
Apply hairspray to a soft cotton or microfiber cloth and rub the paint pen stain.
Repeat any of the three washing methods if the stain remains; try rubbing more vigorously to get the stain to come loose.
