My kids went to a party last month and in the party bags were they sticky people that you can throw at the wall and they stick. However these ones seem to have left awful “people shaped” grease marks on my wall 😡 I’ve tried magic erasers, washing the wall with a wet cloth. Neither worked. Is there anything I can use or will I have to redecorate? If the kids didn’t have such a good time I’d be complaining to the parent!! They are not even small marks and are the exact outline of the little people so they look awful 🤦♀️ Help!
