Key methods to remove rust


null

Rust forms when iron oxidises after coming into contact with air and water. All metals containing iron can rust which weakens the material and cause it to become brittle.

A number of different products can be used to remove rust, including citric acid, soda crystals, bicarbonate of soda, white vinegar, lemon juice and salt and a range of off-the-shelf products, such as oven cleaner. You can even go for more unusual solutions such as onions and potatoes!

First of all, you'll need to equip yourself with gloves and a mask. You'll also need a few basic items such as a basin, scrubbing sponge and a cloth to dry the surface. You may also want to use a spray bottle, wire brush, steel wool or an electric sander (if you have a large area to clean).

Once you're done, don't forget to prevent rust from coming back by treating your tool or object and storing it correctly.

Safety precautions for removing rust

No matter which products you decide to use, you will need to follow a few safety precautions. Remember: if the product is strong enough to remove rust, it is likely to pose a danger to your skin and respiratory system!

It's always best to protect your hands with gloves, use respiratory protection and wear safety goggles. Ideally, you should work outdoors or in a well-ventilated room.

Removing rust using household products

Used on their own or in combination with other products, household cleaning products can be powerful weapons for removing rust.

Citric acid


null

Citric acid occurs naturally in citrus fruits and can be used for a wide range of cleaning tasks in the home, such as removing limescale. But it's also an excellent rust remover. Put on your gloves, mix 5 tablespoons of citric acid with 1 litre of warm water.

Depending on the surface you want to treat, you can apply the mixture using a scrubbing sponge or simply spray it on. Scrub vigorously, rinse then dry.

Soda crystals


null

Wearing a pair of gloves, pour some soda crystals onto a damp scrubbing sponge.

Give the object a good scrub, use another sponge to rinse then dry carefully.

Bicarbonate of soda (and vinegar)


null

Bicarbonate of soda can be used for a range of tasks around the home from cooking to cleaning. It is also touted for its rust-removing properties whether mixed with water to create a paste or combined with white vinegar.

If you use vinegar, you will create a highly effervescent mixture that should ideally be applied to your surface with a paint brush.

Either way, the bicarbonate of soda mixture should be left for about fifteen minutes before you rinse and dry the surface.

White vinegar and salt


null

Pour some salt into a basin and add roughly equal parts white vinegar.

Be careful: when mixed, these products produce a chemical reaction that produces effervescence. Dip a sponge into the mixture, then rub the rust vigorously. Rinse, then dry carefully.

Lemon juice and salt


null

Lemon is a powerful weapon against rust and salt only makes it more effective. Squeeze the juice from a lemon into a basin.

Add two or three spoonfuls of salt and dip your sponge into the mixture. Use it to scrub the rust. You can leave the mixture to work for a few hours before rinsing and drying.

Onion or potato


null

A surprising but effective old-fashioned trick involves cutting an onion or potato in half and rubbing it directly onto the surface until the rust disappears!


Household cleaners

Removing rust by hand

As is often the case, nothing beats a bit of elbow grease for removing rust.

Wire brush


null

It is sometimes possible to get rid of rust simply using a wire brush and a lot of effort!

Steel wool


null

Simply scrub any affected surfaces with some fine grade steel wool.

Tinfoil


null

Ideal for small areas of rust or tricky-to-reach spots, tinfoil can be balled up or rolled around the tip of your finger to lift off rust.

Electric sander


null

If you are dealing with a particularly large area of rust, you can use an electric sander or grinder fitted with sandpaper. Start with a coarse grit and work your way towards a fine grit.

Oven cleaner


null

While usually used to clean grimy ovens, oven cleaner can also be used to tackle rust.

Spray it onto the surface and leave for a few seconds before rinsing and drying.

Rust remover


null

Rust removers can usually be applied to all types of surfaces to remove rust in a matter of seconds, without the need for sanding or scrubbing.

How to prevent rust from returning


null

Once you've eliminated the issue, you will have to make efforts to ensure the rust doesn't come back. An anti-rust primer, varnish or  a special paint can be applied to prevent rust from reappearing.
