Our new housekeeper told me about Mr. Clean Magic Eraser, which can be purchased in any grocery market. It is a white sponge that, when dampened, will remove virtually any marks from your walls without leaving smudges...crayon and pencil marks, scuffs from suitcases or other things dragged against your walls. I cannot tell you how often I have had walls repainted due to such marks and the new housekeeper tells me this product is the ticket. Being at the bottom rung in the domestic goddess hierarchy, I was skeptical. But purchased a box of the miracle cure and it is incredible. Husband's big laugh of the week is any discovery by moi of a household cleaning product, but he's not exactly Handyman Hal himself. You can find Mr. Clean in many places other than a blue toilet bowl.
