If you want to get it off painted walls: use your hairdryer and heat the area for about 30 seconds, it will melt the wax, wipe as you go along with piece of tissue or similar, you will notice that some of the crayon shifts, when you've done this, use a non scratch scourer and soapy water. Don't scrub too hard else the paint will shift!!!

And keep the culprit out of the room while you do it else like mine they want to help!

Don't worry about the Library book. I was told by my local Library that they expect this sort of thing with the childrens books. They don't charge (they don't where I live anyway).

Actually, that would be useful too! She got blue crayon on the wall during DH's watch and he scrubbed it off. Result = no paint left on wall.

can' but I know how to get it off painted walls!!!!1

No, I'm far too lazy to have sorted it already. And besides, I needed the collective wisdom of MNs.

baby wipes!

hairspray worked for me when DS got red crayon on beige carpet.

spray on hairspray and dab off with kitchen roll
that is if you haven't sorted it already

DD is normally so good at crayoning on the paper only, so I stupidly let my concentration drift for a minute... The result is red crayon on a pale cotton dress and on a hard-backed library book. The only trick that I can think of is to put some paper towel over and try to iron it out, but I'm worried that that might make it spread. Does anyone have any tips please?
