Each wallpaper id different! Please always consult us before attempting to clean your wallpaper. If your wallpaper is washable, use a sponge lightly dampened with a solution of water and a small amount of dish soap. Make sure you do not get the wallpaper too wet. It is best to have a dry cloth with you to wipe up the excess solution. Finish this washing process by rinsing the wallpaper with a lightly dampened cloth or sponge with water alone. Then immediately dry the wallpaper with a terry-cloth towel. Certain uniquely textured wallpaper cannot be washed. You can test whether your wallpaper can be washed by picking an inconspicuous spot of wallpaper and applying your solution of dish soap and water to it. If the wallpaper absorbs the water or the colours run, it is not washable. Even if your wallpaper is washable do not use abrasive cleaners.
