- Dry cleaning has proven to be the best and easiest method for all types of chalk boards.
- Erase the entire surface with a clean felt eraser and then wipe with a soft, lint-free cloth or dry chomois.
- To remove foreign matter, such as stains, fingerprints, crayon, pencil marks etc. it may be desirable to wash the board with water. A mild household cleaner may be used on stubborn stains. Avoid the use of strong cleaners containing oil, soda, kerosene, or harsh abrasives.
- Dry the chalk board immediately so that the chalk dust will not dry on the surface, producing a gray file or smeary condition.
