Over time, your favorite brass pieces can lose their shine as oxygen, water, and other elements cause the metal to corrode or tarnish. Fortunately, there are many simple ways to bring luster back to your brass items. With our editor-tested methods for cleaning brass, you only need basic household supplies and a few minutes of your time to restore the shine to hardware, doorknobs, decorative objects, and other brass items.
Here are the best ways to clean brass and restore its original luster using household products.
Brass Cleaning Tips
Just because an item looks like brass doesn't mean it's pure. Check the metal with a magnet; if it sticks, it's not real brass. Many items are brass-plated, and most cleaning methods could damage them. If the item is brass-plated, soap and water on a soft cloth is the safest choice.
Also, check to see if the brass has been lacquered. Most cleaning methods will damage lacquered brass, so your best option is to take the piece to a professional.
Test the chosen cleaning method in a small, inconspicuous area on the brass item. For stubborn stains, try several cleaning methods—one at a time—on the same spot until you find one that works.

How to Clean Brass with Lemon and Baking Soda
Lemon juice and baking soda are powerful natural cleaners on their own, but when united, this dynamic duo removes brass buildup with ease.
Combine Ingredients
Start by squeezing the juice from half a lemon into a bowl. Add 1 tsp. baking soda and mix.
Apply and Buff
With a clean cloth, rub some of the mixture onto the brass. Polish and buff away grime, reapplying the mixture as needed.
Wipe and Dry
Wipe away any leftover residue with a wet rag. Then dry with a clean cloth.
Try this method on brass items that you can't easily soak, such as doorknobs and knockers. You'll revive the shine without having to remove any hardware.
How to Clean Brass with Flour, Salt, and Vinegar
To make tough stains disappear, combine salt's abrasive power, vinegar's acid, and all-purpose flour as a thickener.
Combine Salt and Vinegar
In a medium-sized bowl, add 1 tsp. salt to 1/2 cup vinegar. Stir the mixture until the salt dissolves.
Make a Paste
Add about 2 Tbsp. of flour to the salt and vinegar mixture to make a paste.
Apply Paste
Rub the paste onto your brass object and let it dry for 10 minutes.
Rinse and Dry
Rinse, wipe clean, and thoroughly dry the brass with a clean cloth.
How to Clean Brass with Ketchup
Ketchup provides a straightforward method for reviving old brass, thanks to an acid in tomatoes that removes tarnish. This simple cleaning hack requires only the condiment and a few clean cloths.
Test First
Start by squirting a small amount of ketchup onto the brass in an inconspicuous spot, such as the bottom. Let it sit for a few seconds, and then wipe clean with a damp cloth. If it works well, repeat the process on the remainder of the brass piece.
Apply Ketchup and Wipe Clean
After a successful test, apply ketchup to the brass item and let it sit for a few seconds. Wipe the item clean using a damp cloth.
Rinse and Dry
Rinse thoroughly and dry with a clean cloth.
How to Clean Brass with Toothpaste
The gentle abrasives in toothpaste can work their cleaning magic on brass. To clean brass with toothpaste, pick a plain, white toothpaste (you don't need any gels or fancy flavors).
Apply Toothpaste
Apply a thin layer of toothpaste to your brass object. Let it rest for a few minutes.
Polish Brass
Polish with a clean cloth. For tough spots, you'll likely need to use a bit more effort. Feel free to apply extra dabs of toothpaste to particularly stubborn areas.
Rinse and Dry
After the brass is polished to your liking, rinse with cool water and dry with a microfiber cloth.
How to Clean Brass with Soap and Water
Sometimes, the simplest brass cleaning methods are the most effective. If you're short on cleaning supplies, try dish soap and water to clean tarnished brass.
Mix Soap in Water
Make a warm bath for your brass in a clean container and mix in a few tablespoons of liquid dish soap.
Soak and Scrub Brass
Soak the brass for a few seconds. Use a microfiber cloth or clean toothbrush to remove any stains. The warm water and soap will do some of the work, but this method might still require a bit of elbow grease!
Rinse and Dry
When all the tarnish is gone, remove the brass piece from the soapy water. Rinse and wipe dry with a clean cloth.
Other Methods to Clean and Polish Brass
If you prefer to use a commercial brass cleaner, be sure to choose one that's specifically designed for brass. You can easily find these tried-and-true brass cleaners on Amazon and at a variety of other retailers, including Brasso metal polish ($5), Bar Keepers Friend Cleanser ($6), and Mr. Metal liquid polish ($9). Always wash the item with mild soap and water to remove dust or other debris before polishing. Then, follow the manufacturer's instructions carefully to clean and polish your brass item.
Brass polishes typically leave a protective coating on the surface, which helps prevent future tarnish and discoloration. To keep your brass looking shiny and clean, avoid touching the piece often (the oils on your skin can accelerate tarnishing), and use a soft cloth when cleaning or polishing to prevent scratches on the surface. With regular upkeep, your brass will maintain its beautiful shine for years.
Frequently Asked Questions
Can WD-40 be used to clean brass?
Yes. Spray a small amount of WD-40 on a soft, clean cloth and gently rub it into the brass in a circular motion. Let it sit for 15-30 minutes, then remove it. Be sure to test it on a small spot first to ensure it won't damage your piece.
Is there a way to clean old brass without removing the patina?
To preserve the patina, use mild soap and water and wipe the brass gently. Don't use abrasive or acid-based cleaning products because they'll remove the patina.
Does vinegar dull brass?
Vinegar can dull brass if left on the surface for too long or if the brass is scrubbed too hard with vinegar. Use vinegar sparingly when cleaning brass, and always use it mixed with water or other products to minimize the abrasiveness.
