My three year old son got a hold of a pencil and marked up several walls about three weeks ago just before we took a long trip. I have used an eraser and dishwasher soap to try to clean the marks and it does not seem to be working well. The walls on which the pencil marks are located have latex paint on them. Can anyone tell me the best way to get rid of the pencil marks? Any help would be greatly appreciated. Thanks,
JD
