How do you get old marks off of dry erase boards?

To remove old marks from a dry erase board, use a paper towel and hand sanitizer. After cleaning the board with hand sanitizer, spray the board with water, and dry it with a paper towel.

1. Clean the dry erase board with hand sanitizer

   Squeeze hand sanitizer on a dry paper towel, and clean the entire surface of the dry erase board. Apply more hand sanitizer to the paper towel as needed, and continue cleaning.

2. Spray the board with water

   Spray the dry erase board with water, and use a clean paper towel to wipe away the residue. Use a dry paper towel or wash cloth to dry the board.

3. Repeat the process

   If ink remains on the board after cleaning, squeeze more hand sanitizer on a new paper towel, and repeat the cleaning process. The dry erase board should be free of marks and residue after a second cleaning.

4. Use rubbing alcohol

   If you don’t have hand sanitizer, rubbing alcohol also works. Use a cotton ball instead of a paper towel to absorb the rubbing alcohol. Clean the board with the rubbing alcohol, then spray with water, and dry with a paper towel. Repeat the process as needed to completely remove old marks from the board.
