One. What to do about fabric wallpaper accumulating dust?
The most effective way to remove dust and debris from fabric wallpaper is to vacuum. Before starting, attach the wallpaper brush extension to the vacuum cleaner. You may need to use a ladder to reach higher areas of the wall, depending on the extension length. Begin at the top of the wall and work your way down, cleaning in small sections. Gently brush the wallpaper to remove all dust and debris.

Additionally, you can use a feather duster to lightly dust the surface, but be sure to move the duster from the top of the wall to the bottom when removing dust.
II. How to clean fabric wallpaper
Fabric wallpaper can be easily cleaned with a damp cloth for minor stains, and regular dusting is sufficient. Fabric wall coverings are susceptible to water damage. Due to the material properties, water stains can easily leave marks or cause the wallpaper to deform.
For stubborn stains, you can use regular household or specialized cleaning agents.
Please note that cleaning fabric wallpaper can be quite difficult, so it is important to maintain good hygiene and cleanliness of the walls.
