Basic Dust Removal: Lightly sweep away surface dust with a soft-bristled brush or feather duster, or gently wipe with a low-pressure water gun and a damp cloth. Avoid vigorous sanding to prevent scratching the surface coating.
Stain Removal: Daily water stains and dust can be wiped with water. For stubborn stains such as oil and sauces, dilute a neutral detergent (such as dish soap) and gently wipe, then wipe clean with water. Do not use strong acid or alkali cleaners to prevent corrosion of the surface coating.
Outdoor Cleaning: For high-rise exterior walls, use a long-handled cleaning brush with water. For lower-rise walls, use a low-pressure water gun directly. Avoid direct high-pressure water jets onto the joints of the panels to prevent moisture penetration.
Special Stains: For adhesive tape or stickers on the wall, gently wipe with adhesive remover, then clean with water. Metal scratches can be repaired by lightly sanding with fine sandpaper and applying a small amount of stone protectant.
