Step 4: Cleaning The Board

After every section, you should clean the board. Usually factories will bathe the entire board in a cleaning solution, but that is problematic to do in a classroom because it creates a lot of fumes, or gases that are harmful to breathe. So we will use a paper towel instead.

It will get more difficult to remove the crud the longer you wait to do it, so do it as quick as you can.

Tools Needed

Paper towel

Rubbing alcohol



  1. Apply rubbing alcohol to a microfiber or paper towel.

    Alcohol is flammable!

    Keep the alcohol away from the iron at all times.

  2. Gently dab, don't rub, on the surface, so that lots of alcohol flows onto the surface.

  3. Now scrub the surface with a toothbrush, making sure to get off the debris of where you applied the alcohol. Do make sure to scrub until the surface is no longer wet from the alcohol and is clean from debris.

    Keep scrubbing!

    Don't be shy! Keep scrubbing until you are satisfied. It won't be perfect, and it doesn't have to be. A clean board will look better and last longer.
