Crayon and Walls don't mix

Anyone have a solution to remove Crayola crayon from walls besides a Magic Eraser. I'm all out and I found 3 more 'works of art' and have people coming over later tomorrow. HELP!

Sponge, dish soap and elbow grease.

got out the spotless 2 book - walls in spotless 1 dont have but for cothes carpet etc the abridged version is to mix 2 drops of tea tree oil and a teaspoon of dishwashing detergent. rub with fingers dab off with cloth to remove colour before wiping to reduce spreding. I have never tried this one.
I usually get it off with a steam machine thing.
Best of luck


Edit
just tried it with a purple crayon it worked really well used fingers then tissue

I'd try a warm iron over a paper towel placed over the art, to lift the wax. Then scrub with a mild soap.
Not sure if it'd work, but I'd try it.

I was also going to suggest an iron and old shirt...but I am not sure it would work for that either, but it does work for candlewax in carpet.

Texter on doors that are painted.. 4 get it and repaint god damn kids!!

Kitchen paper on it and then iron it.
It takes the grease.
Remove the rest with acceton.

Kye Eucalyptus(spelling) oil for texta Rub on neat and will work for crayons too. We never had textas when my eldest was little. She couldn't help herself. She has two little boys of her own now. hehe.
