Crayons on the wall?

I used to have a printed out sheet, in which it explained how WD40 and duct tape are all the tools you need in the world. It was hilarious, and so true. "If it moves and isn't supposed to, use the duct tape. If it doesn't move and it should, use the WD40."

If you have ever despaired about cleaning the crayon off your walls, did you know that WD40 works? Like a charm. (Well, you may get a teeny tiny bit of a hue there, but since I didn't scrub too awfully hard, it's possible that you could get it all the way gone.) Feel free to let your chilren roam with crayons now.

Thought I'd share that lovely house-mama tip.
