It's natural for unlacquered brass items to tarnish over time, and finding the best way to clean brass while preserving their beautiful finish can be a challenge. We have tested several brass cleaning methods and come up with the 5 easiest and most effective ones that really work. You can easily bring back your brass items' gleam with a few household products.
Important: If you have a lacquered brass item, you should be aware that these cleaning methods may damage it. The methods below are designed for raw or unlacquered brass. If you are unsure which type you have, check for a perfectly uniform, mirror-bright finish — that is typically lacquered brass.
Method 1: How to Clean Brass with Baking Soda and Lemon
The fast-acting paste — results in 10 minutes
Before & After
Ingredients
Mix one teaspoon of baking soda with one teaspoon of lemon juice and stir until it becomes a paste. Rub the mixture all over the sink, shower fixture, kitchen faucet, or bathroom faucet with a soft rag, let it sit for 10 minutes, then rinse with warm water.
If you are impatient and want to get the job done without waiting, this method is for you — the mixture acts quickly on the surfaces of the item for a satisfying result. Lemon juice is acidic which will keep your brass from turning green, while the mild abrasiveness of baking soda gently polishes away existing tarnish without scratching.
- Mix 1 tsp baking soda with 1 tsp lemon juice — stir into a smooth paste
- Apply to the brass surface with a soft cloth, rubbing in small circular motions
- Leave for 10 minutes
- Rinse thoroughly with warm water
- Dry immediately with a clean soft towel
Method 2: How to Clean Brass with Lemon and Salt
The targeted scrub — precise control on specific spots
Before & After
Ingredients
Mix equal parts of table salt and lemon juice until the salt is dissolved — or simply take half a lemon and coat the cut surface with salt. Rub it directly on the tarnished brass for 10 minutes until clean, then rinse with warm water.
This method is very efficient but you must be careful while rubbing. If you scrub too hard, rub marks may be left behind. Using lemon and salt will provide a long-lasting shine that is resistant to tarnish — the lemon's acidic juices penetrate the brass, loosening oxidation while leaving a protective coating.
- Cut a lemon in half and coat the cut surface generously with salt
- Rub directly onto the tarnished brass with light, circular pressure
- Work for up to 10 minutes on standard brass; no longer than 60 seconds on unlacquered brass
- Rinse thoroughly with warm water — remove all residue
- Dry immediately and completely
On unlacquered brass: limit acid contact to 60 seconds maximum to avoid stripping the natural patina unevenly.
✦ Best for: spot-cleaning specific tarnished areas on fixtures and hardwareMethod 3: How to Clean Brass with Flour, Salt, and White Vinegar
The thorough paste — best for heavy tarnish
Before & After
Ingredients
To make a cleaning paste, use equal parts of flour, salt, and white vinegar. Combine the ingredients in a small bowl and stir together. Apply the mixture to the tarnished brass. Leave for an hour before scrubbing, then rinse with warm water and dry with a clean soft towel.
The recipe only has 3 ingredients easy to find in any kitchen cupboard, and safe to use together. The vinegar breaks down the tarnish while the salt acts as a gentle abrasive so you can remove it without scratching the metal. The flour completes the paste, helping remove excess vinegar while leaving behind a smooth surface.
- Combine equal parts flour, salt, and white vinegar in a bowl
- Stir into a thick paste — add more flour if the mixture is too runny
- Apply generously to all tarnished areas
- Leave for 30 minutes to 1 hour depending on how heavy the tarnish is
- Scrub gently with a soft cloth, then rinse thoroughly with warm water
- Dry immediately and completely
Method 4: How to Clean Brass with Ketchup, Tomato Sauce, or Tomato Paste
The convenient method — one ingredient, already in your fridge
Before & After
Ingredients
Ketchup, tomato paste, and tomato sauce all work equally well. Apply a layer of whichever one you choose to your brass and leave it on for an hour. Then wash with warm water and dish soap and let it dry. This method is easy, economical, and effective — all you need is one ingredient.
Ketchup and tomato paste contain an acid that helps to remove tarnish on brass and other metals. The acetic acid from vinegar combined with mild tomato acids dissolves surface oxidation without abrasion — it works on the same principle as the lemon-salt method, just less precisely formulated.
- Apply a generous layer of ketchup, tomato paste, or tomato sauce to the brass surface
- Leave for 30 minutes to 1 hour
- Wash off with warm water and a small amount of dish soap
- Dry thoroughly with a soft cloth
Method 5: How to Clean Brass with Lemon and Dish Soap
The gentle routine — daily maintenance without abrasion
Before & After
Ingredients
Run lemon juice over the brass surface. Let it sit for 30 minutes, then scrub with a soft toothbrush and dish soap. Rinse well and dry with a clean, lint-free cloth or a soft towel. This is the gentlest of the five methods — suited to regular maintenance rather than deep cleaning of heavy tarnish.
Avoid scrubbing too hard — you may scratch the brass. Avoid using harsh chemical cleaners as they are abrasive and will damage the surface and finish. Do not use any of these methods if the brass is lacquered or varnished.
- Apply lemon juice to the brass surface with a cloth, or squeeze directly
- Leave for 30 minutes
- Scrub gently with a soft toothbrush and a small amount of dish soap
- Rinse well with warm water
- Dry with a clean lint-free cloth or soft towel

What to avoid when cleaning brass
- Steel wool and abrasive scouring pads — permanently scratch the metal surface
- Bleach and bleach-based cleaners — cause chemical damage and discoloration
- Ammonia-based cleaners — strip patina unevenly and can cause pitting
- Acid left on longer than a few minutes — lemon juice or vinegar sitting too long will etch the surface
- Brasso on unlacquered brass — designed to strip oxidation, it reverses months of natural patina in one application
- Dishwasher for any brass item — the heat and detergent will permanently damage the finish
The safest rule: use the gentlest method that works, rinse promptly, dry immediately. Standing water causes more uneven tarnishing than any cleaning product — wipe your brass fixtures dry after every heavy use.

Cleaning unlacquered brass: a different approach
Most brass cleaning guides assume you want your brass to look new again. If you have unlacquered brass fixtures — faucets, sinks, cabinet hardware — that is the wrong goal. Unlacquered brass develops a natural patina over time: a warm darkening shift from bright gold toward amber, then toward deep bronze. This patina is the finish. The cleaning methods above can remove it if applied too aggressively.
Cleaning unlacquered brass is not about restoration. It is about maintenance. The routine is simpler than most people expect.
Why lemon works — and when to stop
60 seconds. No longer.
For mineral spots on unlacquered brass, cut a lemon in half and rub it directly on the affected area, then rinse thoroughly with warm water and dry immediately. The mild citric acid dissolves mineral build-up without harming the underlying metal.
The critical difference from standard brass cleaning: stop after 60 seconds. Prolonged contact strips the patina unevenly, leaving bright patches surrounded by darker areas that take weeks to re-equalise on their own.
60 seconds, then rinse. Leaving acid on longer strips the patina unevenly.
What to use and what to avoid on unlacquered brass
Safe to use
- Warm water and mild dish soap
- Soft microfibre or cotton cloths
- Lemon juice (rinse after 60 seconds)
- Renaissance wax for light protection
- Mineral oil in coastal environments
- Flour + salt + vinegar (heavy tarnish only)
Never use
- Brasso or commercial metal polishes
- Vinegar-based cleaners left to sit
- Bleach or ammonia-based products
- Abrasive pads or steel wool
- Acid contact longer than 2 minutes
- Dishwasher for any brass item
Brasso and most commercial brass polishes are designed to strip oxidation. Used on unlacquered brass, they reverse months of natural ageing in a single application. This is the most common mistake buyers make when their faucet first starts darkening — they reach for a polish when a wipe with soapy water would have been sufficient.

"We love our handmade brass taps from the wonderful @insideastdesigns. The patina is looking absolutely perfect. Like honey."
Elliss Eyre renovated a home in Portugal — a humid southern European climate — and specifically remarked on the patina after regular use with nothing more than warm water and a cloth. Honey-toned. Warm. This is the outcome for the vast majority of buyers who maintain their fixtures without aggressive cleaning products.
"A simple update on our beautiful brass faucet... the patina is so lovely! Enjoying the spring sunshine filling our old farmhouse kitchen. I walk in and all I see is this timeless beauty."
