Identify the material and finish
Look for the maker's care guidance and determine whether the item is solid metal, plated, coated or lacquered. A green or dull area may be oxidation, wear, a reaction with a cleaner or damage to the finish. Do not assume that every patina should be removed.
Start with gentle, approved care
Remove ordinary dust with a soft dry cloth. If the manufacturer permits damp cleaning, use a compatible cloth and mild product sparingly, then dry the surface. Test only as directed in a hidden area and stop if colour transfers or the finish changes.
Avoid aggressive polish and chemical mixtures
Acids, ammonia, abrasive powders, metal polish and scouring pads can damage plating, lacquer, nearby stone or protective finishes. Use them only if the item maker explicitly approves the product and method. Never mix cleaners or apply a product near electrical, gas or plumbing parts without appropriate guidance.
When to call a specialist
Antique fixtures, flaking plating, corrosion, pitting, leaks or hardware connected to plumbing may require a metal-restoration or plumbing specialist. Cleaning cannot restore missing plating, repair corrosion damage or fix a leaking fitting.
