How to Clean Your Fixtures Without Damaging the Finish: A Material-by-Material Guide

Most damage to sinks, tubs and faucets is not wear — it is cleaning. The wrong product on the wrong surface dulls enamel, scratches stainless steel and strips the finish off a faucet, and none of that is covered by a warranty. The fix is simple: clean each material with something made for it.

The three rules that apply to everything

No abrasive powders or scouring pads on any finished surface. Steel wool, green scrub pads and gritty powders leave fine scratches that hold dirt and make the surface harder to clean next time.
Rinse and dry. Most water spots and mineral build-up come from water left to evaporate. A quick wipe with a soft cloth after use prevents most of the scrubbing.
Test first. Try any new cleaner on a small, hidden area before using it on the whole fixture.

Enameled cast iron sinks and tubs

Cast iron is coated in a glass-like enamel that is very hard but can be dulled by abrasives and harsh acids. Use a cleaner made for enameled cast iron, a soft sponge, and rinse thoroughly. Grey marks from pots and pans are metal transferred onto the surface, not scratches in it — a dedicated cast iron cleaner usually lifts them.

Avoid leaving acidic foods, rust removers or strong bleach solutions standing on the enamel.

Stainless steel sinks

Wipe with the grain of the brushed finish, never across it.
Do not use steel wool or wire brushes — they leave particles that rust and look like the sink is rusting.
Do not leave chlorine bleach or bleach-based cleaners sitting in the bowl.
A sink grid on the bottom of the bowl prevents most of the scratching in the first place.

Faucets, showerheads and trim

Modern faucet finishes — polished chrome, brushed nickel, matte black, brushed bronze — are durable, but they are a thin surface layer. Clean them with a mild soap and water or a cleaner made for faucet finishes, and dry with a soft cloth.

Avoid ammonia, bleach, acids and abrasive cleaners on any faucet finish. Matte black and other matte finishes are especially easy to mark with polishing products — never "polish" a matte finish.

For hard-water build-up on a showerhead, many models have flexible rubber nozzles you can rub clean with a fingertip. Check the manufacturer's care instructions before soaking a finished showerhead in vinegar.

Acrylic and solid-surface tubs and shower bases

Acrylic scratches more easily than cast iron. Use a non-abrasive tub and shower cleaner and a soft cloth. Solid-surface and engineered materials should be cleaned with the product the manufacturer recommends for that specific material.

Toilets

Clean the bowl with a toilet cleaner and brush, and the outside with a mild cleaner. Be careful with in-tank cleaning tablets: only use tablets that the toilet's manufacturer approves. Some tablets contain chemicals that attack the rubber flapper and seals, which causes leaks and running.
