Wipe regularly with a soft, damp cloth to remove dust and soap residue. Use mild, pH-neutral cleaners only; avoid abrasive pads, cream cleansers, and harsh chemicals that may damage the matte black finish. Dry after cleaning to reduce water spots and maintain an even appearance. Do not hang heavy items or use the holder as a grab rail to prevent loosening or damage. Periodically check and gently retighten fixing screws if the holder begins to move.
