Help!!!
A friends child leant against a wall in our rented apartment after eating a pepperami and has left a greasy hand print on the wall. 
Its coffee brown matte paint and obviously not washable child friendly paint like any normal human would use
I've not tried anything in it yet, as I'm scared of making it worse! My brain says use something to draw the grease out first... baking powder maybe? Please help, as I really don't want to have to ask the landlord for the paint details and redo the whole wall
