Make up remover

My daughter continued birthday celebration at school with industrial quantities of home made chocolate strawberry whoopies. It is an important day at school, she gets to sit on a trone, and children sing happy birthday on the playing ground. She also gets painted on her cheeks, blue red and silver. This of course has to be removed before bedtime and I asked my son to do this.
I don't think he will go into the cosmetic business, but they had lots of fun.
