Unlacquered brass is designed to change. Unlike chrome or nickel, which hold the same colour year after year, raw brass reacts to its environment: air, water, and light all leave their mark. The result, over weeks and months, is a rich patina that makes each piece genuinely unique. Watermarks and tonal shifts from the moment of installation aren't faults. They're how the material works.
- Unlacquered brass ages on purpose: surface marks and colour shifts from day one are part of the design, not defects.
- In 1stDibs's 2025 survey of 643 interior designers, brass tied with bronze as the most-favoured material of the year, each chosen by 18% of respondents (1stDibs, January 2025).
- Clean with low-pH soap or a 50/50 white wine vinegar-water solution. Never use abrasive cleaners. Pat dry after use to slow limescale buildup.
- The most visible change happens in the first 2 to 3 months. After that, the patina largely stabilises and becomes more self-maintaining.
What Makes Unlacquered Brass Different?
Most metal fixtures are lacquered: a clear protective coating seals the surface and stops the metal reacting with the air around it. Chrome, brushed nickel, satin brass — most of what you see in kitchen showrooms — work this way. The finish you choose on the shelf is the finish you keep indefinitely.
Unlacquered brass removes that coating entirely. The raw metal sits exposed, and it responds to everything it encounters. Oxygen darkens it. Water leaves mineral traces. Light catches the surface differently as it evolves. Metalworkers call the result a patina — the same process that turns freshly bright copper pipes to a warm brown over years, just at a slower pace and in warmer amber and caramel tones on brass.
Your Bidbury & Co Old English Brass or Polished Brass fixture on installation day is the starting point. The finish develops from there, shaped by your kitchen, your water, and how you use it.
Why Designers Are Choosing Unlacquered Brass Right Now
The trend data here is clear. In 1stDibs's 2025 annual survey of 643 interior designers, conducted by Surveys & Forecasts LLC, brass and bronze jointly topped the materials rankings for the year ahead. Each was favoured by 18% of respondents (1stDibs, January 2025). That's a meaningful signal from professionals who specify materials for a living.
What's driving it? Kitchen design shifted toward warmer, more tactile materials across the early 2020s, moving away from the cooler grey-and-chrome aesthetic that defined the previous decade. Unlacquered brass fits that direction naturally. It ages toward amber, caramel, and deep gold tones that read as warm under natural light. And because every piece responds to its specific environment and usage, no two fixtures age identically. That distinctiveness is difficult to replicate with a sealed, lacquered surface.
What to Expect as Your Finish Ages
Three stages characterise most unlacquered brass in daily kitchen use. The pace varies depending on how often the tap is used, the hardness of your water, and how much natural light reaches the surface.
New out of the box: The surface has a pale, bright appearance. Some marks are already present from manufacturing, packaging, and handling. These aren't problems — they're the first signs of the patina forming.
One to two weeks: The colour shifts noticeably warmer. Small blemishes become more pronounced and a new tone starts to settle in. This is the stage that sometimes catches people off guard — the tap looks "less new" — but it's the process doing exactly what it should.
Two to three months: A proper patina has formed. The surface has real depth and tonal variation. Colour largely stabilises here, though the finish continues developing subtly over years of use.
Beyond three months, the rate of change slows considerably. The patina becomes more stable and more resilient — and the early marks that once looked like damage have blended into a surface with genuine character.
How to Clean and Care for Unlacquered Brass
The core principle is straightforward: gentle, every time. Aggressive cleaning doesn't restore unlacquered brass — it strips the patina you've spent months developing. Work with the finish, not against it.
What to Use
- Low-pH liquid soap and warm water. Standard dish soap works well. Wipe, rinse, dry.
- A 50/50 solution of white wine vinegar and water for mineral deposits or stubborn marks. Apply with a soft cloth, leave for one to two minutes, then rinse and dry thoroughly.
- Soft cloth or microfibre only. Nothing abrasive, ever.
What to Avoid
- Bleach, scouring pads, or abrasive cleaning sprays. These strip the patina and can etch the metal.
- Leaving the surface wet after use. Patting dry is the single most effective habit to build.
- Soaking the fitting in vinegar. Short wipe-downs are fine; prolonged acid exposure damages the finish.
How often do you need to clean it? Weekly is plenty for most kitchens. Once the patina is established, the finish becomes fairly self-maintaining — minor marks absorb into the surface rather than standing out against it.
Hard Water and Unlacquered Brass: What UK Homeowners Should Know PERSONAL EXPERIENCE
This is something the wider internet rarely addresses — and it's more relevant in the UK than almost anywhere in Europe. Much of England, particularly the South East, East Anglia, and the Midlands, sits in hard water areas. Hard water carries dissolved calcium and magnesium that deposit on surfaces when water evaporates. On unlacquered brass, this typically shows up as a white hazy ring around the base of the tap, or a pale scale on the spout where water drips and dries.
The minerals themselves don't damage brass. They sit on top of the patina and, if left to accumulate, can obscure the natural finish — but they're easily removed. A diluted vinegar wipe takes limescale off in minutes without affecting the metal. Don't scrub. Wipe, leave for a minute or two, rinse with warm water, then dry. That's all it takes.
If you're in a particularly hard water area, a weekly wipe-down keeps limescale manageable without disturbing the patina underneath. The vinegar approach works better on unlacquered brass than the dedicated limescale removers sold in supermarkets, most of which contain harsher acids that aren't suitable for natural metal finishes.
Frequently Asked Questions
Will unlacquered brass tarnish over time?
Yes — and by design. Unlacquered brass oxidises naturally through contact with air, water, and light, developing a patina that deepens in colour and texture. The result is a warm, aged finish unique to each piece. If you prefer a surface that stays consistent, a lacquered finish such as chrome or nickel is a better match for how you use your kitchen.
How do I stop my unlacquered brass tap going green?
Some greening (verdigris) can appear on unlacquered brass in damp or hard water environments. Patting the tap dry after each use and cleaning weekly with a diluted vinegar solution slows it significantly. If green patches do appear, a small amount of ketchup or lemon juice on a soft cloth removes them quickly — the mild acidity dissolves the oxidation without damaging the metal underneath.
Is unlacquered brass harder to maintain than chrome?
It needs a different approach rather than more effort. Chrome stays consistent but shows watermarks clearly and those marks are permanent on a lacquered surface. Unlacquered brass develops a patina that becomes more forgiving over time — minor marks blend into the aged surface. The main habit to build is patting it dry after use to prevent hard water deposits accumulating.
Can I polish unlacquered brass back to its original shine?
A specialist brass polish will temporarily restore a brighter finish by removing the patina. That oxidation returns fairly quickly once the surface is exposed again to air and water. Most owners find the patina is the point — the aged finish is what gives unlacquered brass its character and why it remains one of our most popular finishes.
How long does unlacquered brass take to develop a patina?
You'll notice a colour shift within the first one to two weeks of regular use, as the surface warms from its initial pale gold. A proper patina — with visible depth and tonal variation — typically forms within two to three months. The pace depends on usage frequency, your local water hardness, and how much natural light reaches the surface.
