How to Remove Grease Stains off a Chalkboard

Daisy Cuinn

Grease stains can make writing on a chalkboard impossible. Chalk will only write on a textured surface, so any grease will leave the surface too slick. Cleaning a chalkboard with soap or solvents can cause a buildup on the surface and possibly spread the grease around.

Clean your chalboard for longtime use.

Clean with dry techniques first before trying anything wet. Specially treated chalkboard cleaning cloth can be found at school supply stores and online.

  1. Sprinkle a small amount of cornstarch on a fresh grease stain. Leave for 20 minutes, then carefully wipe it off with a paper towel.

  2. 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.

  3. 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.
