My stove is up against a plain painted wall. From cooking and frying, there are plenty of greasy spots and stains. I'd like to give the wall a good cleaning and then put something up to make cleaning easier. I'm in an old apartment and can't do much to the apartment. And even if I could, I wouldn't want to put too much money into a crappy old kitchen anyway. Is there anything I could put to make clean easier? Foil paper would be one solution I suppose, but anything that is one step up?
