Getting Rid of Rust by Scraping Off Rust Stains

Another rust removal option is to scrape off the unwanted rust using tools that have abrasive surfaces. This involves a lot of effort and hard work, but it is possible to remove rust this way. There are a number of household objects you can use for this such as screwdrivers and steel wool. You can use any metal tool for the job, but make sure to use fine-grain sandpaper afterwards to remove any scratch marks.

Alternatively, you can go to a hardware store and rent some tools. If you need to get rid of rust from larger surfaces, it is best to use an electric rust remover, such as an electric sander. You should always start with the area that has the roughest grain and gradually move to the less rusty metal areas. This way the roughness of the object is minimised.

How to Get Rid of Rust Using Rust Remover Chemicals

Chemical rust removers are usually made using oxalic or phosphoric acid and therefore are hazardous for the skin so should be used safely. Make sure that you take all necessary precautions before using a chemical remover to remove rust from a metallic object. Carefully read and use the product according to the directions provided as the usage can differ from product to product.

Keep in mind that these chemicals need to be applied for several hours and require you to scrub afterward, so be prepared for a lot of work. You also need to be aware that chemical rust removers are usually expensive and only applicable for smaller objects. Find our top picks for chemical rust removal solutions below:

Rust Converting Chemical Method:

You could buy a rust converter which prevents the rust from reacting further with the metal. Rust converters are like spray paints and serve the function of a primer for a paint layer on the surface. This is effective for preventing the rust from spreading further, but it does not help in completely removing rust from a metal object. You should only use rust converters if you intend to paint the surface of the metal.

Citric Acid Rust Removal:

Citric acid (usually found in a powered box format) is an effective chemical to use for removing rust and can be purchased from most shops.

Put the powdered citric acid in a container made of plastic and add some hot water.

Place your rust covered objects into your rust cleaning solution to restore your tools, equipment, and surfaces back to bare metal. Make sure the container you make the solution in is large enough to fit your metal object in. Completely cover the metal object in the citric acid rust cleaner. Leave it for the night and rinse in the morning. Dry with a clean cloth afterwards.

Oxalic Acid Rust Removal:

You can also use oxalic acid to remove rust. Since this is a strong chemical agent, ensure that you have taken protective measures prior to use. Be sure that you are wearing protective clothing; goggles and rubber gloves – and make sure that you do not inhale the acidic fumes. Create a diluted mixture of water and oxalic acid (25ml acid and 250ml water). Soak the object in this mixture for around 20 minutes or you can also wipe the object with a brass brush or cloth. Once complete and the rust is removed, ensure you wash the item thoroughly and subsequently dry it.

The Best Homemade Rust Removers to Get Rid of Rust

Don't have the time to go to the shops? Not a problem – there are several household items you can turn into a homemade rust stain remover; from mildly acidic fluid-like white vinegar to aluminium foil. Find our top picks of DIY rust removers below:

White Vinegar Rust Removal

You can use white vinegar for effective rust removal. The rust reacts with the vinegar and later dissolves. Simply soak the rusty metal object in white vinegar for a couple of hours and then just wipe to remove the rust. If the object is too large, simply pour white vinegar evenly over the surface of the object and give it some time to settle. Alternatively, you can also use a cloth soaked with white vinegar to wipe the object.

Another solution to clean rust is to use a piece of aluminium foil dipped in vinegar to wipe the rust off the object. Using regular vinegar is also an option, however, it will take more time to remove the rust. Try soaking the object in regular vinegar for 24 hours; this will lessen the amount of scrubbing that would be necessary.

Lemon or Lime Metal Rust Removal:

Lime and salt are another solution to help remove rust from metal items. Simply Sprinkle some salt over the area of the object that has rusted and ensure that it is completely covered. After, squeeze lime or lemon all over it. Make sure you squeeze as much juice as you can and then leave it for about 3-4 hours before you scrub it off. It helps to use the left-over skin for scrubbing the resulting mixture. It is powerful enough to clean rust off metal without causing any damage. A lemon, in replacement of the lime, can also be used in the same way.

Baking Soda to Get Rid of Rust:

Using baking soda and water creates a thick paste that is easily spread over the metal as a rust cleaner. Give it some time to set and then scrub it off. Use a toothbrush to scrub the paste off and then wash it with water. This mixture can be diluted according to your preference. There is no exact specification for the amounts to be used.

How to Remove Rust With Dish Soap and a Potato:

Dish soap and potato are also valuable household items when it comes to cleaning rust. Cut a potato into two pieces and apply dish soap on the cut end. This will ensure that there is a chemical reaction between the end and rust, which will make it easy to wipe off.

Put the potato on the surface of the metal object and let it stay for a couple of hours. If you need to apply again, simply cut the used end off and put dishwashing soap on the fresh end. After that, place it again on the metal surface for longer.

So, there you have it – nine effective methods to remove rust stains from metal. From home ingredients such as lemons and limes to your trusted household lubricant, WD-40® – there is a process to suit everyone. Which rust remover is the best? That's up to you.
