How to Remove Grease Stains off a Chalkboard
- Cornstarch
- Paper towels
- Chalkboard cloth
- Rubbing alcohol
- Acetone nail polish remover
Clean with dry techniques first before trying anything wet. Specially treated chalkboard cleaning cloth can be found at school supply stores and online.
-
Sprinkle a small amount of cornstarch on a fresh grease stain. Leave for 20 minutes, then carefully wipe it off with a paper towel.
-
Wipe the chalkboard with a dry chalkboard cloth, using an overlapping back-and-forth motion over the entire surface. Try marking the area of the grease stain with chalk. If it leaves a mark, the stain has been removed. If it doesn't, continue to the next step.
-
Dampen a cotton pad with rubbing alcohol and rub the stain lightly. When the alcohol has evaporated and the surface is dry, try marking it with chalk. For a stubborn grease stain, use acetone nail polish remover. When the chalkboard is dry and the grease stain has been removed, wipe it down again with the chalkboard cloth.
