When metal rusts, it’s not always a good idea to throw it away and buy a new tool to replace it. Instead, you can save money by manually removing rust stains.
Steps
Remove rust with home remedies
- If the item is too large to soak directly in the white vinegar solution, you can pour a layer of the solution over the item and let it sit for a few hours. You can also use a cloth soaked in vinegar to clean the rust.
- You can try soaking the foil in vinegar and using it as a brush to scrub away the rust. Foil is less abrasive than steel wool, but it will also help you get rid of rust.
- You can use regular vinegar and simply soak metal objects in vinegar for about 24 hours before rinsing them out. You do not need to rub the item.
- Use lemon zest to rub on the mixture. Lemon peel has the ability to remove rust without damaging the metal.
- You can also use yellow lemon instead of regular green lemon.
- You can use a toothbrush to scrub the baking soda mixture, then rinse with water.
- The ratio of baking soda to water is up to you, not an exact ratio.
- You can continue to use this method by slicing off the surface of the used potato and adding more dishwashing liquid, then letting it sit on the metal for a few hours.
- If you don’t have dish soap, you can use potatoes with a mixture of baking soda and water. [1] X Research Source
- Wash rusty items with dish soap and dry carefully.
- Mix 25 ml (one teaspoon is 5 ml) of oxalic acid in 250 ml of warm water.
- Soak the item for about 20 minutes or use a cloth or copper brush to scrub the item
- Rinse and dry the tool once the rust has been removed. Complete!
Remove rust with store-bought materials
- Follow the instructions for use printed on the product packaging, each type of product usually has a different usage.
- These chemicals need to be left to sit for a few hours on metal and need to be scrubbed afterwards, so be prepared to spend a little bit of effort on scrubbing.
- These types of products can be expensive and are usually only effective for removing small rust stains on metal, but cannot be used on heavily rusted surfaces. [2] X Research Source
- This method only helps prevent further corrosion, it is not as effective as completely removing rust on metal objects.
- This is only a temporary option if you plan to repaint the furniture. And this method will also make the surface of the item rough because mainly you just apply a layer of paint to cover the rusted surface.
- Steel wool is usually easy to use and is one of the tools that are commonly available at home.
- Use an electric grinder to remove rust on large objects. You should start with a heavy rust and then slowly move on to a lighter rust to minimize the roughness of the metal.
- Any metal tool can be used to scrape off rust, however, be sure to use fine-grained sandpaper to remove any scratches if present.
- Put a little citric acid in a plastic container and fill it with hot water, enough to submerge the surface of the rusty tool. You can watch the bubble foaming reaction if you like!
- Soak items overnight then rinse and dry.
Prevent rust
- Store metal in a cool, dry place to avoid moisture accumulation.
- Always remember to wipe the metal off after contact with water.
- If the metal surface is smooth, you can use a primer in the form of a spray paint.
- Metal with a rough surface needs to be painted with a brush to cover the slits or holes in the metal.
- Spray paint is also effective for metal objects, however, if applied with a brush, the paint will be more durable.
- Apply a final coat of paint to reduce the rate of oxidation. [6] X Research Source
Advice
- When using chemicals to remove rust, make sure you are in a well-ventilated area. Depending on the chemical, in the process of cleaning objects, toxic fumes may be generated, such as acid fumes.
- Combine the steps together for extra rust removal power. For example, if you want to remove rust on a chain, soak it in vinegar for a few hours, then use steel wool or a wire brush to scrub the item. Metal utensils can rust as they dry, so apply an extra coat of paint to protect them.
