Rust is a type of corrosion that forms on metal when iron interacts with oxygen. It can occur in just a few days, or it can take months. The good news is that you can get rid of rust with common household products and natural cleaners. But it’s important to know the substances you’re using and how to use them correctly to avoid damage.
One of the easiest ways to remove rust is to mix baking soda and water to form a paste. Spread it over the rusty area and let it sit for a few minutes. Scuff the paste with steel wool or a wire brush, and then rinse the metal.
Another method to remove rust is to apply salt and lemon juice. The combination is effective on a variety of stains. Salt has a corrosive effect, which can help dissolve the rust. You can either leave the mixture on the rust for a couple hours, or apply it immediately. If you have an electric sander, you can use it to speed up the scraping process.
Another technique involves applying citric acid to the rust. This can help remove paint and other coatings. However, it is best used on metal objects that can be scrubbed or submerged. Make sure to wear protective clothing, and be patient when rinsing the rusty area.
A less abrasive method to remove rust is to soak the object in vinegar. Regular vinegar is inexpensive and can work effectively. Soak the item in the solution for 24 hours, and then scrub away with a wire brush or steel wool. If the rust is very heavy, you may have to scrub more thoroughly.
When a rusted object is left in vinegar for too long, it may turn black. If you have a large metal object, you may need to place it in a raised bed to prevent it from becoming too soaked.
Another abrasive method for removing rust is to spray a solution of WD-40 on the rust. This will remove multiple layers of the metal and can remove squeaks from doors.
Some abrasive tools can be used to remove rust, and you can rent them from your local hardware store. Typically, you will want to have a wire brush, a soft-bristled brush, and a scouring pad. Scraping the rust requires elbow grease, and the more abrasive the tool, the more elbow grease it will require.
Finally, there are a few other chemical rust removers. Phosphoric acid is a very toxic chemical that can break the bonds of small amounts of rust. However, it is fast acting and can be scrubbed away without much effort.
When choosing a rust remover, consider the size of the rusted metal, and how long the rust has been present. This will help determine which method will work the best. Also, you should keep in mind that some of the ingredients used in rust removers can pose risks to children and pets.
