Few people give cleaning wallpaper a second thought. In fact, few clean it at all. The truth, however, is that wallpaper should be cleaned at least once a month in order to ensure it lasts and retains its original vibrant color and feel. How you clean the wallpaper depends on a variety of factors, including whether stains (and which kind) are present, the colors of the paper and the materials available.
The first step in cleaning wallpaper is to dust it using a dry cleaning cloth. Brush the cleaning cloth in a single direction, up to down, to remove any dust without creating lines or strikes. Follow up with a slightly wet cloth in the same direction. Simple marks, such as fingerprints or pencil/crayon stains, may come off at this point. If they don’t, try using a simple eraser to get rid of them. Don’t brush too hard, though, or you risk ruining the paper.
Cleaning fluid can be used to get rid of more stubborn stains, but don’t spray it directly on the wallpaper. Instead, get the cleaning cloth wet and then rub on the wall. Try it out on a corner or hidden spot first, in case the product affects the color.
