Brass is a beautiful metal that can add a touch of elegance to any home, but what happens when it gets painted over? Fortunately, there are several methods to restore brass that has been painted. The process typically involves removing the paint, polishing the brass, and then protecting the restored surface. This can be done through various techniques, such as boiling the brass in water, using chemical paint strippers, or even just scrubbing with water and a brush. Once the paint is removed, the brass can be polished using a variety of household items, such as lemon and salt, vinegar and salt, or even ketchup. Finally, the brass should be protected with a coating of oil, lacquer, or a commercial product like Brasso. With a bit of time and effort, painted-over brass can be restored to its former glory.

What You'll Learn
Removing paint with boiling water
Yes, brass can be restored once it is painted over. One way to do this is by removing the paint with boiling water. This method is perfect for smaller items like hardware or hinges.
First, find a large pot that you don't plan to cook with again and add water. You can also add dish detergent to the pot, as some sources suggest. Next, place your brass items in the pot and bring the water to a boil. Turn the heat down and let the brass fixtures simmer for at least 6 hours. Then, transfer them to a bowl of ice water for about 5 minutes. This will make the paint easier to remove and the brass safer to handle.
Now that you've loosened the paint, scrub it off with steel wool, a flathead screwdriver, or a toothbrush. You can also try a nylon brush or a sponge, but avoid using abrasive materials that can scratch the surface of the brass, like wire brushes or coarse sandpaper. Work quickly, as the paint will be easier to remove when the brass is still warm. Once the paint is removed, use a damp cloth or sponge to wipe off any remaining paint chips and residue.
Finally, dry the brass item with a soft, lint-free cloth. You can then choose to polish the brass using a lemon or vinegar solution, or a mixture of lemon and salt. For example, cut a lemon in half, sprinkle salt on the flesh, and rub it directly on the brass object. You can also make a paste with lemon and cream of tartar, apply it to the brass, and let it sit for 30 minutes before rinsing with warm water.
If you prefer a more natural approach, you can mix equal parts white vinegar and water in a disposable pot and bring it to a boil. Add 1/4 cup of baking soda per quart of water, submerge the brass items in the solution for about 15 minutes, and then remove them with tongs. Scrape off the loosened paint with a knife or screwdriver.

Using paint strippers
Paint strippers are a common method for removing paint from brass items. Paint strippers are usually based on sodium hydroxide, which is good for removing skin and flesh. Before using a paint stripper, it is important to determine if the item is made of solid brass or if it is brass-plated. This can be done by using a magnet; if the magnet does not stick, the item is made of solid brass, and it is safe to use a paint stripper. If the magnet sticks, the item is likely brass-plated, and a paint stripper should not be used.
When using a paint stripper, it is important to follow the product instructions and take safety precautions. Some paint strippers have a strong smell, so it is recommended to use them outdoors or in a well-ventilated area. It is also important to protect your skin and eyes by wearing gloves and eye protection.
There are various types of paint strippers available, including liquids, gels, and creams. Some common paint strippers used for brass include:
- Citristrip: This paint stripper has a mild odour and can be used indoors. It is applied directly to the brass surface and left to penetrate the paint.
- Nitromors: This paint stripper is commonly used in the UK and is effective in removing paint from brass.
- Acetone: Acetone is a powerful solvent that can remove most paints and lacquers. It should be used with a soft rubbing medium, such as steel wool, to avoid marring the brass.
After applying the paint stripper, it is important to allow it to penetrate the paint for the recommended amount of time. Then, use a nylon brush or steel wool to scrub the paint off. For intricate details and cracks, a toothbrush can be used to remove the remaining paint. Once the paint is removed, wash the brass with hot soapy water to remove any residue from the paint stripper.
In some cases, paint strippers may not completely remove all the paint. If there is any remaining paint or residue, it can be removed with mineral spirits, denatured alcohol, or vinegar. These substances can be applied with a non-abrasive sponge or towel to wipe away the remaining paint.

Cleaning with natural products
Brass can be restored once it is painted over. The first step is to strip off the paint. This can be done by simply using water, or by adding the brass item to a pot of boiling water and letting it boil until the paint wrinkles. The item can then be scrubbed with steel wool or a brush to remove the remaining paint.
Once the paint is removed, the brass can be cleaned with natural products. Here are some methods for cleaning brass with natural products:
Lemon and Salt
Cut a lemon in half and sprinkle salt onto the flesh. Rub the lemon on the brass item and polish with a soft cloth until shiny. Rinse with water and dry with a soft cloth.
Lemon and Cream of Tartar
Combine one part lemon juice with two parts cream of tartar and mix until it forms a paste. Apply the paste to the brass item and let it sit for 30 minutes. Rinse with warm water, then wash with hot soapy water, rinse with cool water, and dry with a soft cloth.
Lemon and Baking Soda
Mix one tablespoon of lemon juice with one tablespoon of baking soda to form a paste. Apply the paste to the brass item with a soft cloth, let it sit for 10 minutes, then rinse with warm water.
Vinegar and Salt
Combine one cup of white vinegar with one tablespoon of salt. Add enough flour to make a paste. Spread the paste over the brass item and let it sit for 30 minutes to an hour, then rinse with warm water and dry with a soft cloth.
Olive Oil
Olive oil can be used to clean brass items and protect against future tarnishing.
Vinegar and Baking Soda
Mix half a cup of baking soda with one cup of white vinegar to create a paste. Apply the paste to the brass item and let it sit for 30 minutes, then rinse off. Repeat if necessary, then rub with olive oil to add shine.
It is important to note that these methods may not be suitable for lacquered brass items, as they can be damaged by some cleaning solutions. Lacquered brass should be soaked in a paint stripper and scrubbed with steel wool to remove the lacquer before attempting to clean the brass.

Polishing techniques
Before attempting to restore brass, it is important to determine whether the item is made of solid brass or is brass-plated. This is because brass-plated items, which are made of different base metals such as zinc or steel, require different care. To identify solid brass, place a small magnet on the item; if the magnet does not stick, the item is made of solid brass.
Once you have confirmed that your item is made of solid brass, you can begin the process of restoring it. If the brass has been painted over, you will first need to strip off the paint. This can be done by adding the hardware to a crockpot or slow cooker filled with water and bringing it to a low boil. Let the hardware boil for a few minutes until the paint wrinkles up on the metal. Then, remove the hardware and lay it on paper towels. Using steel wool, scrub the paint off the metal.
After removing the paint, you can begin polishing the brass. One method is to create a paste by mixing baking soda, white vinegar, and table salt. Apply the paste to the brass and let it sit for 30 minutes before rinsing it off. Then, rub the brass with olive oil to protect it and add shine. Another method is to cut a lemon in half, sprinkle salt on the flesh, and rub the lemon directly on the brass. Finally, polish the brass with a soft cloth until it is shiny.
If your brass item has scratches or flaws, you can use fine-grit sandpaper to lightly sand away at the scratches until they are even with the surrounding surface. For brass that is in relatively good shape, start with higher-grit sandpaper (around 800 grit), and for more beat-up brass, start with lower-grit sandpaper (around 320 grit). Wet sanding is recommended when working with brass as it helps to minimize the spread of sanding residue and create a smoother surface.
To protect your brass item and keep it looking new, you can apply a protective coating of oil or clear lacquer. Lacquer-based sealants provide a harder, more durable finish that resists oxidation and is ideal for ornate pieces. Waxing, lacquering, and dusting can also help to protect your brass item and keep it looking good for years.

Protective coatings
Lacquer
A lacquer coating can be applied to brass items to prevent tarnishing. Lacquer is a clear coating that dries to form a hard, protective layer. It is available as a spray or in a tin for application with a brush. It is important to note that lacquered brass may need to be re-lacquered in the future as the lacquer can wear off, exposing the brass to tarnishing.
Oil
Applying a thin coat of oil to brass items is another effective method of protection. Oils such as olive oil or mineral oil can be used. The oil penetrates the brass, creating a barrier against moisture and oxygen, which are the main causes of tarnishing.
Wax
Wax is a traditional method of protecting brass and other metals. It provides a natural shine and protection against moisture. Waxing is a simple process that involves rubbing the wax onto the brass surface and then buffing it to a shine.
There are also specialised protective coatings available, such as ProtectaClear, which is an easy-to-apply, scratch-resistant coating that keeps brass shining for years. It is practically invisible and can be maintained indefinitely.
Polishing
Regular polishing is another way to protect brass and keep it looking its best. Polishing compounds such as Brasso can be used to remove tarnish and restore shine. Polishing creams like Midas Touch Polishing Cream are also effective and gentle on brass.
It is important to note that protective coatings should be reapplied periodically, especially if the brass item is exposed to moisture or high traffic. By utilising these protective methods, you can ensure that your brass items maintain their beauty and shine for years to come.
