When your wanting to get crayon makrings off the walls that your little ones may have left behind there are a couple of easy ways I have found without having to repaint. First one I found is nail polish remover. All You do is take a paper towel and put some of the nail polish remover on the paper towel and go over the area and then repeat if neccessary. Secondly I found that the Mr. Clean magic eraser works good too. All you do is simply wet it then go over the area and repeat if needed.
