Wallpapers can be cleaned by vacuuming or dusting it with a sponge or soft cloth. When vacuuming your wallpaper, use a soft brush attachment to ensure that you do not damage the texture.
If your wallpaper is washable, you can use a sponge lightly dampened with 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 any excess water. Always rinse the wallpaper with a lightly dampened cloth or sponge with just water. Immediately dry the wallpaper by dabbing with a cloth/towel.

Some 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. Please note that even if your wallpaper is washable do not use abrasive cleaners and always proceed with caution.
