Had a little accident with some wunderweb whilst ironing, a bit caught on the dress and has left some white residue. Does anyone know how I can get it off.
Try popping it in the freezer, see if you can pick it off afterwards? (NB this is entirely at your own risk, I've not tried it, don't say I made you do it if your dress falls to bits!)
Spray it with water and then iron over it. It should transfer it to the iron. Then spray the iron with water and rub the iron over a piece of old rag and it should come off!
