Another way that might work is try keeping the chalkboard in the sun, when the wax from the crayon gets hot enough you might be able to just wipe it off the board.

The answer is actually probably Mr. Clean bricks. So far I have never come up against something they wouldn't handle. I would steer clear of acetone or polish remover; it eats about anything. You can still get Jubilee-it now comes in a spray form.

Warm iron over a cloth like as undershirt should absorb crayon.

Jubilee is a kitchen wax product - sort of a cream that is white colored. It will remove crayon from walls, etc. quite well. My mother had to do this after one of my sisters colored a wall in our new house as a child. I think it is still made. If you can't find it you might look for another waxing cleaner as that is what crayons are mostly made of anyway.

I would try a heat gun & paper towels, if you don't have one try a hot blow dryer. Also, as a last resort, try fingernail polish remover & paper towels.
