Removing crayon from blackboard?

Any suggestions?
The colour is gone but there are still waxy marks from where DS1 drew on teh chalkboard

I'm thinking wd40 :think:

thats what I was just discussing with DH, but I'm worried it will coat the surface in the same way?

I was going to suggest that as well followed by a wash with some dishwashing detergent and water...

Rayray i have the same problem ... Hope someone has a solution in which it has been trialed by them ;)

(I was thinking a light swip of nailpolish remover but scared it will take heap of surface off which will look worse then it does now :rolleyes:)

Found this on the crayola website. Sounds like whats been suggested here so I will try it and report back :)

Thanks Ray ... so hope it works brilliantly for you ... Yeh, do PLEASE let us know what worked then i will have a go on DD's chalkboard :D

If it doesn't work, you can repaint the surface - blackboard paint comes in small tins and is pretty cheap (I've always got free leftovers from work, so i don't know how much it costs) but it's easy.

hi, i just use ajax the bi carb soda one no idea if it has a different effect to the stabdard one and a cloth comes off quick and easy every time
