Cleaning and Maintenance
After installation, the walls and wallpaper should be monitored for potential moisture or vapor infiltration or accumulation. Any such infiltration/accumulation after installation must be promptly eliminated in order to reduce the risk of mold/mildew growth.
STEP 1: Start by removing surface dust. All types of wallpapers must be dusted with a microfiber cloth regularly - at least once every 2 months. For hard-to-reach places near the ceiling, attach your cloth to a long-handled sweeper. you can also vacuum walls, using a brush extension. Make sure the vacuum head does not have bristles and is simply sucking up dust, not scouring the wall. Begin at the ceiling, and swipe the vacuum head down the wall in long, smooth lines.
STEP 2: Deep clean wallpaper with soapy water. In a bucket, mix 1 gallon of water with 1/4 cup of mild dish soap or castile soap. Then, dip a soft, non-abrasive sponge into the soapy water and ring it out until it's just damp. Then wipe down the wallpaper.
