We just moved into our new house beginning.of December. back then the walls were spotless!! all a sort of creamy yellow colour. roll on to now nd there is allsorts marking them.:-(:-Q I've tried wiping but some of the paint comes off. how do I get them clean with out having to reprint the whole kitchen?! I wouldst be able to just touch up cause I don't have any paints that match the wall :-( or shall I just buy some cheap magnolia and paint.it all?
