- The best thing you can do to keep the wall covering in most rooms looking pristine is the simplest: vacuum it. A soft brush attachment on a vacuum cleaner works best — and is a must if the paper is flocked or has any kind of texture. Start at the top of the wall and work your way down, doing a couple of panels at a time.
- Be careful of cobwebs. Lift them up with the vacuum; if you try brushing them away, they may streak the wall. Depending on how dusty your house gets, dust every few months. A microfibre cloth on a long-handled sweeper or a clean white cloth wrapped on the end of broom will also work on flat, non-textured wall coverings.
- Natural coverings — grass, reed, hemp, cork, leather, fabric — and uncoated wallpaper are easily damaged by water and cannot be washed.
- To find out if a wall covering is washable, squirt a little dishwashing liquid in water and dab some on the wall in an out-of-the-way spot. If the material darkens or absorbs water — or if the colours run — the covering is not washable. Clean it with wallpaper dough.
