How to Clean and Maintain Brass and Copper

How to Clean and Maintain Brass and Copper | Patinaty

Solid brass and copper fixtures are built to last, and caring for them is simpler than many people expect. The right routine depends on your finish and on the look you want: a deep patina, a bright shine, or something in between. This guide covers everyday care, deep cleaning and long-term maintenance for our three finishes: Unlacquered Brass, Antique Copper and Polished Nickel.

Before You Start: Three Simple Rules

Start gentle. Mild soap and warm water solve most cleaning needs. Move to stronger methods only when necessary.
Test first. Try any new cleaner or polish on a small, hidden area before using it on the whole fixture.
Always rinse and dry. Leftover cleaner and standing water cause most spots and uneven marks. A soft, dry cloth after cleaning makes a big difference.

Everyday Care for All Finishes

For routine cleaning of faucets, pot fillers and accessories:

Wet a soft cloth or microfiber towel with warm water and a few drops of mild dish soap.
Wipe the fixture gently, paying attention to handles, the base and the underside of the spout.
Rinse with a clean damp cloth to remove any soap.
Dry thoroughly with a separate soft cloth.

Drying after use, especially around the base of a faucet where water collects, is the single most useful habit for keeping any finish looking its best. It also reduces water spots in hard water areas.

Caring for Unlacquered Brass

Unlacquered brass has no protective coating, so it develops a patina as it reacts with air, water and touch. How you clean it depends on whether you want to keep that patina or remove it. If you are new to the finish, read What Is Patina? first.

To Keep and Encourage Patina

Clean only with mild soap and water, then dry.
Skip polish entirely. Every polishing removes some of the patina that has built up.
Expect uneven tones. Handles and textured areas age differently, and that variation is part of the look.

Our article How to Clean Unlacquered Brass Without Removing the Patina covers this approach in more depth.

To Restore the Original Shine

Clean the fixture with mild soap and water and let it dry.
Apply a small amount of a non-abrasive brass polish to a soft cloth, following the product directions.
Rub gently in the direction of the grain or along the shape of the fixture.
Buff with a clean cloth, then rinse or wipe away any residue so it does not keep reacting with the metal.
Dry completely.

Some people prefer a homemade paste, such as lemon juice with baking soda, or white vinegar mixed with salt and flour. These mild acids work, but they should be applied briefly, rinsed off thoroughly and dried, and always tested on a hidden spot first. See Natural Brass Cleaners: What Works and What to Avoid and How to Restore Shine to Unlacquered Brass.

To Slow the Patina

After polishing, you can apply a very thin coat of microcrystalline wax with a soft cloth and buff it out. Wax reduces contact with air and moisture, so the brass stays brighter for longer. It wears off with use and cleaning, so reapply occasionally on high-touch pieces.

Caring for Antique Copper

The Antique Copper finish is meant to look aged. The goal of cleaning is to remove dirt, not color.

Clean with mild soap and warm water, rinse and dry.
Do not use metal polish or acidic pastes. They strip the darkened tone and reveal bright metal underneath, leaving a patchy look that is hard to reverse.
If small green spots appear where moisture has lingered, wipe gently with a soapy cloth and dry the area well.
A light coat of wax can add a subtle sheen and help repel water if you wish.

This care applies to accessories like the Antique Copper Sink Strainer as well as larger pieces. Learn more in Antique Copper Finish Explained.

Caring for Polished Nickel

Polished Nickel is a bright finish applied over a solid brass body. It is stable and does not develop a patina, so care is about keeping it clean and spot-free.

Clean with mild soap and warm water using a soft cloth.
Dry after each cleaning to prevent water spots on the reflective surface.
Do not use brass polish, abrasive powders or scouring pads, which can scratch or dull the finish.
Avoid acidic cleaners, including vinegar left on the surface for long periods.

Hard Water and Mineral Spots

Hard water leaves pale, chalky deposits on every metal finish. Prevention is easiest: dry the fixture after use. To remove existing spots:

Start with warm soapy water and a soft cloth.
For stubborn deposits on unlacquered brass, wipe briefly with a cloth dampened with diluted white vinegar, then rinse and dry right away. Note that vinegar will brighten brass where it touches, so treat the whole surface evenly if you want to avoid patches.
On antique copper and polished nickel, keep acidic contact very short, or contact us for advice before trying it.

If you have a removable aerator on your faucet, unscrewing it occasionally to rinse out mineral buildup can help maintain water flow. See Removing Hard Water Spots From Brass and Copper.

What to Avoid on Every Finish

Abrasive pads, steel wool and scouring powders
Bleach, chlorine-based cleaners and harsh bathroom or oven cleaners
Ammonia-based glass cleaners
Drain cleaners splashing onto fixtures or drains
Spraying cleaners directly onto the fixture and leaving them to sit. Spray onto a cloth instead.
Leaving wet sponges, soap bars or cleaning products resting against the metal

Damage from harsh chemicals or abrasive cleaning is not covered by our warranty, so gentle cleaning protects both your fixture and your coverage.

Handles, Cartridges and Moving Parts

If a handle becomes stiff or a faucet begins to drip, the cause is usually an internal part rather than the finish. Replacement cross handles with cartridge are available, and our Replacement Parts and Support page explains the next steps. We recommend having a licensed plumber handle any work on supply connections.
