Crayon all over the wall......

[ilovespinach]

I leave my toddler alone for 2 minutes and he has crayoned all over the wall ( in a lovely florescent pink...).

What is the best method for getting this off? I tried a baby wipe and it got it off but has discoloured the wall...We live in a rented flat and have lovely white woodchip all over the walls .....

I have seen some special wipes you can get to remove childrens art from the wall. Is it worth getting these?

Thanks

you know those spongy things (JML and flash make them) that are said tor emove all- erasers i think they call them? do this a treat
