DD2 is distraught because she has accidentally put a big, blue wax crayon mark on her Hello Kitty cushion. It's new, it was a birthday present and, of course, it's meant to be as white as the driven snow!
I've done a load of googling, but am still not sure how to proceed. A lot of the suggestions seem to involve ironing/putting WD40 on the back of the stain. But as it's a stuffed toy, I can't get at the back of it. And I don't fancy using WD40 on something she's going to want to cuddle in bed.
