- 1). Note, when you buy the paper, what the store and the manufacturer recommend for both cleaning and protection.
- 2). Use a sponge or rag to lightly apply soapy water to vinyl-coated paper.
- 3). Apply a special cleaning gel or liquid to paper that is not already coated with some kind of protection (rare these days). If you don't know what kind of paper you have, bring a sample to the store - even if you have to take a piece from some inconspicuous place on your wall. Or pick that same spot and experiment with different cleaners.
- 4). Protect your wallpaper by applying a protective coating - also a liquid or gel that you can buy. Before you apply the coating, be sure the paper is clean and dry, or you might have to live with a disagreeable stain forever.
