Proper maintenance is required to preserve all finishes. Clean the faucet periodically with clean waters, rinse thoroughly with warm water and dry with a clean, soft cloth. Please do not use any harsh chemicals as these will dull/corrode the finish (such as hand wash, liquid soap, soap, dishwashing liquid, bath cream, etc) and also any hard cleaning tools (like hard brush, stainless steel scrubber, sandpaper, etc) is forbidden because it will scrape the surface and plating.
