How do you get wax crayon off a wall?

GREASE PROOF PAPER and a warm iron and then and ice cube I believe is worth trying.

then next up is good old toothpaste. which is mild abrasive and a tiny bit bleaching (if it's white) so be careful.

A soap and a clean towel works for me.

WD40 may also be of assistance (apply it to the cloth, not directly)

As daft as it may seem, but suncream is very effective. I had permenant pen on the windows at work and suncream managed to rub it off

It's mentioned in that link, but dry board markers will take permanent marker off a dry white board (draw over the perm marker then rub off), would probably also work for glass.

This definitely works - I tried it after someone at work accidentally used a sharpie on one of the whiteboards.

WD40 fixes everything
