Cleaning brass is admittedly not the most fun chore on the planet. We get it. However, if you want brass that doesn’t look tarnished and lackluster, you must clean it! So let’s talk brass.




How do you clean and polish brass naturally?

Why should you clean brass?

Over time, oxygen, water, and other chemicals that are present in the air can cause certain metals, including brass, to tarnish and corrode. This means they require regular cleaning and maintenance to ensure that your brass items retain their luscious gold color and shine.

In some cases however, it may be better to let your brass items tarnish over time, especially if they are considered to be antiques. Weirdly, tarnish may contribute to increased value. We suppose this is because tarnished brass lends itself to an “antique” look. Consider getting your brass items verified by an antique specialist before you attempt to clean them. In the case of brass-plated items, the thorough rubbing during the cleaning process could end up removing the layer of brass it’s plated with.

Grove Tip

Check your materials

Remember that before you clean brass, make sure it’s actually brass. The easiest way to check this is to stick a magnet to your brass items. If the magnet doesn’t stick, you can rest easy!

How often should you clean brass?

Brass items require regular dusting to maintain their shine and to prevent a buildup of tarnish. A more intense cleaning is required when you see that the brass has already become tarnished and corroded.

Things you’ll need to clean brass

Brass can be cleaned with simple pantry staples, though in some cases you may need a proper brass cleaner. We’ve listed out some items below to help you on your cleaning journey.


  • Baking soda
  • Vinegar
  • Lemon
  • Salt
  • Ketchup - who knew that ketchup actually contains acids that make it an efficient cleaner? It has a high acetic acid content due to the vinegar used in its making. The thick texture of the ketchup also makes it great for shining silverware, copper, and brass. Did we mention it is eco-friendly and cost-effective?
  • Dish soap
  • Soft cloth
  • Tooth brush
  • Gloves

How to clean brass naturally: step-by-step instructions

The best homemade brass cleaners

If you're in a time bind or want to save some cash and not shell out for a brass-specific cleaner, there are a number of homemade options that can get your brass back to gleaming.

How to clean brass using ketchup

Squirt some ketchup on the brass and let it sit for a while. After a half an hour or so — preferably a full hour — has passed, use a soft, damp cloth or toothbrush to rub the brass clean. Once you have removed the buildup, rinse and wipe away the ketchup with a clean cloth and dry the brass.

How to clean brass using lemon and salt

Cut a lemon in half, remove the flesh, and apply salt on the inside. Rub the brass with this lemon, reapplying salt as needed. Clean and dry the brass with a soft cloth.

How to clean brass using vinegar

For the toughest stains and buildup, make a paste with vinegar, flour, and salt, ensuring that the salt is completely dissolved. Rub the mixture generously onto the brass item and let it sit for about 10-20 minutes. Rinse and wipe with a damp clean cloth.

How to clean brass using lemon and baking soda

These two cleaning agents, when united, create a cleaner that’s tough enough to remove brass buildup with ease. Make a paste of lemon juice and baking soda and apply to brass with a clean cloth. Polish and buff away the grime, and wipe away any residue with a wet cloth. Dry your brass item with a second clean cloth.

The best storebought brass cleaners & polish


If you'd rather go the conventional route, opt for a natural, plant-based cleaner or brass polish to protect your fixture or item from harsh, corrosive ingredients.

How to clean brass using soap and water

The easiest cleaning method we know of is to simply make a mixture of soap and water to clean your brass. Soak the brass in this mixture for a while, then use a soft cloth and a soft-bristled toothbrush to work out the buildup and stains. Rinse and wipe dry with a clean cloth.

Sustainability Tip

Avoid chemicals

For lacquered brass items, cleaning can be tricky. They are covered with a thin, transparent layer of protection, making it almost impossible to clean at home. Most cleaners include acids or chemicals that end up damaging the lacquer. If that sounds like your brass items, you may want to seek the help of someone that knows what they are doing.

Brass cleaning tips & tricks

How do you clean badly tarnished brass?

Hot water, baking soda, and salt. You can’t go wrong! Or try one of the homemade methods above — any paste will give your cleaning agents some grittier "oomph" for dealing with tarnished brass.



Does WD-40 clean brass?

Yes, although other methods may work better. It will definitely give your brash renewed shine, though!



How do you remove green oxidation from brass?

Once your brass turns green, it may seem like you’ll never get it’s shining color back — the good news is that just isn’t true. Use a salt-and-vinegar mixture with one cup of vinegar and one tablespoon salt. The mixture will create a paste that you can rub on your brass to remove the green coloring. After the green oxidation has been completely removed, you can rub a little olive oil on your brass to make it shine like new.



Can you clean brass with toothpaste?

This might surprise you, but yes, you sure can clean brass using just toothpaste. All you need to do is to use a clean cloth to put a small amount of toothpaste onto your brass. Let the toothpaste sit for a few minutes, and then rinse it off with cold water.



Can you clean brass with Coke?

Although it’s not our personal go-to for cleaning brass, Coca-Cola can be used to clean brass. Actually, any type of cola soda can be used, too. Just rub the cola of your choice on your brass and leave it for about 10 minutes so it can really sink in. Afterward, give it a rinse to reveal your newly cleaned metal.
