How to Clean Brass Hardware: Caring for Unlacquered & Lacquered Brass

Brass hardware is one of the few things in a home that actually gets more interesting over time — if you know how to look after it.

But not all brass is the same, and neither is the care. Whether you've got Unlacquered Brass developing its own story or a Satin Brass finish holding its shine, this guide covers everything you need to keep it looking exactly how you want it.

First: what kind of brass do you actually have?

Before you reach for the polish, it helps to know what you're dealing with. A magnet is your quickest diagnostic tool. Hold one up to the hardware — solid brass won't attract it at all. If it sticks, the hardware is brass-plated over steel or iron, which means the care rules change: warm water and soap only, no polishing, or you risk stripping the plating entirely.

You can also check the colour. Brass with a higher zinc content sits on the yellower, brighter end. Higher copper content pushes it toward a warmer, redder tone. Neither is better — they just age a little differently.

Once you know it's solid brass, the next question is whether it's lacquered or unlacquered. Here's how to tell:

• Lacquered brass has a clear protective coating over the metal. It holds a consistent colour, resists tarnishing, and stays largely the same over time with minimal intervention.
• Unlacquered brass has no coating. It reacts directly with air, moisture and touch — developing a warm, deepening patina that makes each piece genuinely unique.

If you bought from Plank Hardware, the product listing will tell you clearly. When in doubt, order a swatch set — it's the most reliable way to see and feel the difference before committing.

Caring for Unlacquered Brass.

Unlacquered Brass is a "living" finish — which is either its greatest selling point or its most misunderstood characteristic, depending on who you ask. Without a lacquer to slow things down, the brass reacts naturally with its environment: oils from hands, humidity in the air, the proximity of a steamy kitchen. Over months and years, it develops a patina — a rich, deepening warmth that no factory can replicate. Every piece ages differently, based on exactly where it is and how often it's touched.

That's not a flaw. It's the whole point.

If you've chosen Unlacquered Brass, you've chosen a finish that rewards a certain kind of neglect. The less you fuss with it, the more character it builds. That said, there's a difference between letting it age gracefully and letting it get genuinely grubby — so here's how to find the balance.

Day-to-day maintenance.

A soft, dry cloth is all you need for regular upkeep — wipe away fingerprints and dust as and when you notice them. For anything more stubborn, a small amount of mild dish soap in warm water works well. Rinse thoroughly afterwards and dry immediately; water left sitting on the surface can cause uneven spotting.

If you want to restore the shine.

Some people want their Unlacquered Brass to stay bright. That's entirely valid — it's your hardware. A specialist brass polish like Brasso or Bar Keepers Friend will bring it back. Apply with a soft cloth, buff gently, wipe away all residue and dry completely. The brass will oxidise again over time — how quickly depends on its environment — so this becomes a regular ritual rather than a one-off fix.

Natural cleaning methods.

If you'd rather not use commercial polishes, two DIY methods work well on unlacquered brass:

• Lemon and bicarbonate of soda paste: Mix lemon juice and bicarbonate of soda into a paste. Apply to the surface, leave for 10–15 minutes, then rinse thoroughly and dry completely.
• Vinegar, salt and flour paste: Combine equal parts white vinegar, salt and plain flour into a paste. Apply, leave for 10–15 minutes, rinse and dry. The mild acidity lifts tarnish without scratching.

What to avoid.

• Abrasive pads or scouring sponges — they'll scratch the surface and cause uneven tarnishing that's difficult to reverse.
• Harsh chemical cleaners — bleach-based products in particular can cause permanent discolouration.
• Leaving hardware wet — moisture accelerates patination in unpredictable ways, especially in kitchens and bathrooms.

💡 If you love the patina look, the simplest approach is to simply wipe the hardware clean and leave it alone. The finish will find its own depth.

Caring for Satin Brass and other lacquered finishes.

Most brass hardware — including Plank Hardware's Satin Brass range — is lacquered. A clear protective coating over the metal keeps the colour stable, slows tarnishing considerably, and means very little maintenance is needed in the day-to-day.

The trade-off is that you can't polish lacquered brass back to a brighter shine — and you shouldn't try. Commercial metal polishes strip or cloud the lacquer, which is difficult or impossible to repair at home. Once the coating is damaged, you're essentially left with poorly finished unlacquered brass, which isn't what anyone is going for.

Routine cleaning.

• Dust regularly with a soft, dry cloth.
• For more thorough cleaning, use warm water with a small amount of mild dish soap. Rinse well and dry immediately — don't leave water sitting on the surface.

What to avoid.

• Metal polishes of any kind — Brasso, Bar Keepers Friend, anything abrasive.
• Rough cloths or scouring pads — these will scratch through the lacquer.
• Strong cleaning sprays, particularly anything acidic or bleach-based.
• Prolonged contact with moisture — in bathrooms especially, wipe hardware dry after splashes.

If the lacquer does eventually wear in a high-contact spot — a handle used forty times a day will see more wear than one used twice — the exposed brass will begin to develop patina in that area. Some people find this characterful. Others prefer a consistent finish throughout. If it's the latter, it may be worth considering whether Unlacquered Brass was always going to be the better long-term choice for high-use locations.

A word on Antique Brass, Aged Brass and Heirloom Brass.

These three finishes get confused regularly, and it's worth being clear on how they differ — particularly because their care requirements aren't identical.

Antique Brass.

Antique Brass is a lacquered finish applied over a darkened brass base. The dark, aged appearance is built in from the start — it's not a living finish that continues to evolve. Because it's lacquered, the cleaning rules are the same as Satin Brass: soap and water only, no polishing, protect the coating.

Aged Brass.

Aged Brass is a deeper, richer finish — darker than Antique Brass with more of a warm, bronzed quality. Like Antique Brass, it's a lacquered finish, so it follows the same care routine: gentle cleaning, no abrasives, keep it dry after contact with water.

Heirloom Brass.

Heirloom Brass is the answer for anyone who wants the warmth and depth of an aged patina without committing to the ongoing maintenance of Unlacquered Brass. It's a lacquered finish designed to look like it's already lived a life — the character is baked in, and it stays consistent over time. Soft cloth, warm soapy water, job done.

Common mistakes to avoid.

• Using the same polish on everything. Brass polish is for unlacquered brass only. Using it on lacquered finishes — Satin Brass, Antique Brass, Aged Brass, Heirloom Brass — damages the coating and can't be undone easily.
• Letting water sit on the surface. Moisture is fine during cleaning; it's the sitting that causes problems. Always dry thoroughly immediately after washing, especially in bathrooms and kitchens.
• Confusing patina with damage. On Unlacquered Brass, darkening and colour variation is normal and intentional. It's not a sign that something has gone wrong.
• Using abrasive materials. Rough sponges and scouring pads will scratch brass — lacquered or not. Soft cloths only.
• Not checking what you've actually got. Different brass finishes need different care. The magnet test and a read of the product description are five seconds well spent before you reach for the cleaning cupboard.

Frequently asked questions.

Does unlacquered brass tarnish?

Yes — and that's by design. Unlacquered Brass has no protective coating, so it reacts naturally with air, moisture and the oils in your hands. Over time it develops a patina: a warm, darkening layer that builds gradually across the surface. Some people actively love this and leave it alone entirely; others prefer to polish it back regularly. Both are valid approaches. The finish is yours to manage however you like.

How often should I clean brass hardware?

For lacquered finishes (Satin Brass, Antique Brass, Aged Brass, Heirloom Brass), a quick wipe with a soft cloth whenever you notice dust or fingerprints is sufficient — no set schedule needed. For Unlacquered Brass, the same applies if you're embracing the patina. If you're polishing to restore shine, how often you do this depends on how quickly it oxidises in your environment — kitchen hardware near steam will tarnish faster than a bedroom handle.

Can I use Brasso on lacquered brass?

No. Brasso and similar metal polishes are designed for use on bare, uncoated metal. On lacquered brass they'll strip or cloud the protective coating, leaving an uneven surface that's difficult to repair. Soap and warm water is all lacquered brass ever needs.

What's the difference between Satin Brass and Unlacquered Brass?

Both start from a similar warm, golden base — but they behave very differently over time. Satin Brass is lacquered, meaning it holds its colour consistently with minimal maintenance. Unlacquered Brass has no coating, so it evolves — developing a rich patina that varies depending on its environment and use. Satin Brass is lower maintenance and more predictable; Unlacquered Brass is more characterful and more hands-on.

What's the difference between Antique Brass and Aged Brass?

Both are lacquered finishes applied over a pre-darkened brass base, so neither will continue to age significantly over time — what you see is what you keep. Antique Brass sits in the warmer, lighter end of the dark brass spectrum; Aged Brass is deeper and more bronzed. The care routine for both is identical: gentle cleaning with soap and water, no polishing.

Can I remove the patina from unlacquered brass if I change my mind?

Yes. If your Unlacquered Brass has developed more patina than you'd like, a brass polish or one of the DIY paste methods (lemon and bicarbonate of soda, or vinegar, salt and flour) will bring it back to a brighter tone. It'll begin to oxidise again over time, but you can polish it back as often as you like without damaging the hardware.

Is brass hardware suitable for bathrooms?

Yes, brass hardware works well in bathrooms — all Plank Hardware pieces are designed for residential use including wet areas. The main consideration is moisture management: always dry hardware thoroughly after splashes, and don't leave water sitting on the surface. For high-humidity bathrooms, a lacquered finish (Satin Brass, Antique Brass, etc.) is generally easier to maintain than Unlacquered Brass, which will patinate more quickly in a steamy environment. That said, plenty of people deliberately choose Unlacquered Brass in bathrooms precisely because the patination is faster and more dramatic.

What is brass made from?

Brass is an alloy of copper and zinc — the proportions of each affect its colour, hardness and how it ages. Higher zinc content gives a brighter, yellower tone; higher copper content pushes it toward a warmer, redder hue. It's non-magnetic, highly durable, and doesn't corrode easily — which is why it's been the go-to material for architectural hardware for centuries.

Brass hardware is one of those things that rewards the right amount of attention — not too much, not too little.

Know what finish you have, follow the right cleaning method for it, and the rest looks after itself. Whether you're letting a patina build or keeping things consistently bright, the hardware will hold up.
