Please wash the surface with a wet sponge or cloth to clean it. When wiping the wallpaper for the first time, ink residue may come out due to the printing process. However, this does not affect the real colors of the design or the quality of the material.
Always wipe the wallpaper vertically. Never use an adhesive tape mask on the surface of the wallpaper. For better protection of the wallcovering, a protective varnish is recommended, especially in bathrooms, kitchens and other humid environments.
