On the back of the general wallpaper sample book, you'll find icons that indicate the level of scrub and water resistance of the wallpaper. These symbols help users understand how to properly clean and maintain the product.
A single water ripple icon means the wallpaper has standard water resistance. For cleaning, you can use a vacuum cleaner or a soft brush to remove surface dust. If there's light dirt, gently wipe it with a damp sponge. Be careful not to rub too hard to avoid damaging the surface.
Two water ripples indicate better water resistance. You can still use a vacuum or brush for daily maintenance. For more stubborn stains, a slightly damp cloth can be used. Just make sure to apply gentle pressure during the cleaning process to protect the wallpaper’s finish.
Three water ripples mean the wallpaper has excellent scrub resistance. It can withstand more rigorous cleaning. In addition to using a damp cloth, you may also use a small amount of mild detergent. However, always ensure the detergent is neutral and safe for the material to prevent discoloration or damage.
A water ripple combined with a brush icon shows acceptable wear resistance. This type of wallpaper can be cleaned with a wet cloth and mild detergent, or gently brushed if needed. It's suitable for areas that experience moderate traffic or occasional spills.
Three water ripples along with a brush symbol represent the highest level of durability. These wallpapers are ideal for high-moisture or high-traffic areas such as bathrooms and kitchens. They can be cleaned with water and detergent or even scrubbed with a brush. Their strong resistance makes them perfect for challenging environments.
