Remove permanent marker stains that remain on a chalk board's surface in minutes with the help of a few household products. The porous surface of a chalk board makes it possible to remove spots of permanent ink with a simple soap and water wash. Stained and marked up chalk boards are often taken down, set aside or left unused. Restore an older used chalk board to it former glory and save money on purchasing a replacement.
Pour a few drops of isopropyl alcohol on the corner of a non-abrasive sponge.
Rub the alcohol soaked corner all over the permanent marker stain in a circular motion.
Add a few drops of isopropyl alcohol to a dry corner on the same sponge and return to the spot for a second round of rubbing in small circles.
Examine the effectiveness of the isopropyl alcohol treatment after the spot has been left to dry for 10 minutes. The alcohol may be all that is needed to remove light or small permanent ink marks. Continue on if the mark remains.
Pour a few drops of acetone on the corner of a clean non-abrasive sponge.
Rub the acetone soaked corner on the permanent mark in a circular motion.
Allow the spot to dry and continue with a second application of acetone using a new corner of the same sponge.
