Clean surfaces regularly with mild liquid soap and warm water, then rinse and dry with a soft cloth. Avoid abrasive pads, cream cleansers, and citrus or acid-based products, as they can damage the brushed nickel finish. Do not use bleach, ammonia, or harsh chemicals. Wipe off water spots promptly to reduce mineral build-up. If needed, use a soft microfibre cloth to gently buff the surface back to an even sheen.
