How to Clean Rust Off Metal


If you have rust on your metal piece, you may wonder how to clean it. Fortunately, there are several DIY rust removal methods you can try. These include WD-40, lemon juice, and baking soda. You can even use Oxalic acid. In addition, a mixture of baking soda and water will remove rust from metal.

Baking soda

Use baking soda to clean the area to remove rust from the metal. You can either mix it with water and make a paste or use a wire brush. Apply the paste to the affected area, and allow it to sit for a few hours. It should stick to the metal and peel off the rust. Repeat this process as needed.

You can also use vinegar, which can also help remove rust. It effectively cleans up rust because it contains acetic acid, which reacts with the rust and forms water and salt. This solution can also remove rust from stainless steel and chrome.

Lemon juice

Lemon juice is an excellent method to remove rust from metal. It loosens the rust and acts as a mild abrasive. It will not leave scratches on the metal; it is also environmentally friendly and free of chemicals. The rust residue that lemon juice leaves is easy to remove if the item is thoroughly rinsed. If the rust is nasty, you can use borax to remove it. Make sure that you mix the solution well and that it’s spreadable and not too runny.

Lemons contain citric acid, which is a natural disinfectant and cleaner. It can also be used to clean rust from metal and porcelain. Lemons can also help remove mineral stains and dust. Lemon juice also contains antibacterial elements. In addition to removing rust stains, lemon juice helps clean and deodorize metal and porcelain.

Oxalic acid

Oxalic acid is an excellent choice to clean rust off metal. It works by reacting with the iron to form an iron oxalate complex ion that can be easily washed off with water. Its effectiveness has been well-documented by scientists and is inexpensive and widely available. For best results, you should dilute oxalic acid to a solution of 250ml water and soak the object in it for 20 minutes. After this time, you can see the rust disappear.

Oxalic acid is a natural acid that can be purchased at many different stores. It is available in various strengths and is biodegradable, which means it is safe for the environment. However, it must be used safely as the fumes can be toxic. In addition, when cleaning rust off metal, a safe, non-combustible surface is essential.


WD-40 is a multi-purpose lubricant that is effective in loosening rust and other types of metal. It works by penetrating the rust’s porous layer and uses its lubricating properties to loosen the rust. It is also effective in removing surface rust and can be used to scrub off loose rust from paint-free surfaces. It can also prevent rust corrosion and enhance the look of metal.

The WD-40 Multi-Use Product is most suitable for cleaning rust off metal or concrete. For best results, spray liberally with the lubricant and scrub with an abrasive. Avoid using wire brushes, as they may damage the concrete surface. Nylon brushes are ideal for this task, as they can penetrate deep into the rust stain and lift it.


Potatoes are an excellent natural abrasive and are effective at removing rust from metal. Potatoes are high in oxalic acid; a chemical used to dissolve rust. A potato paste can be used to clean rusted metal by combining it with a gentle abrasive. You should apply the paste to the rusted metal and let it sit for a few hours before rinsing and drying.

This method is best for mild rusting. First, cut a potato in half and cover it in dish soap to make it easier to apply. The rust will dissolve because the oxalic acid in the potato reacts with the soap. If you don’t want to use dish soap, try mixing baking soda and water and apply them to the rusted metal.


One of the best ways to get rid of rust is to use a combination of salt and lime. You can sprinkle the salt on the rusted metal and squeeze the lime over it. You want to squeeze as much juice out of the lime as possible. Leave the mixture on the metal for about 3 to 4 hours before rinsing it. The lime is strong enough to scrub away the rust without causing damage to the metal.

You can also use a combination of salt and vinegar to remove rust stains from larger objects. Lemon or lime juice is also an excellent rust remover. You can also use the fruit’s rind to scrub away light rust. You may want to dilute the lemon or lime juice with some water, so it is more robust. This will leave the metal smelling like citrus.
