How to Remove Corrosion from Steel?

Steel is a durable and reliable material, but corrosion can still occur. Corrosion is a chemical reaction that happens when steel comes into contact with moisture or other elements, like salt water or air pollution. This reaction causes rust and pitting, which can damage the surface of the steel. Fortunately, there are several ways to remove corrosion from steel surfaces safely.

Removing Corrosion With Mechanical Methods

The simplest way to remove corrosion from steel is to use mechanical methods such as sanding, grinding, or wire brushing. These methods will remove the rust and pitting on the surface of the steel, creating a smooth finish. Be sure to wear protective gear such as gloves and a face mask while using these methods, as they make dust particles that could be harmful if inhaled.

Removing Corrosion With Chemical Solutions

Chemical solutions can also be used to remove corrosion from steel surfaces. Common chemicals used for this purpose include phosphoric acid and citric acid. Phosphoric acid converts iron oxide (rust) into ferric phosphate, which can be easily washed away with water. Citric acid works similarly but is less aggressive than phosphoric acid and, therefore, safer to use on delicate surfaces. When using chemical solutions, it’s important to wear protective gear such as gloves and safety glasses and follow manufacturer instructions carefully.

Preventing Future Corrosion

Once you’ve removed the corrosion from your steel surface, it’s important to prevent it from occurring again. Applying an anti-corrosive coating such as paint or wax can help protect your surface from further damage caused by moisture or other elements that could lead to corrosion again in the future. It’s also important to regularly inspect your steel surfaces for signs of corrosion so you can address them immediately before they worsen.


Removing corrosion from steel may seem daunting, but it doesn’t have to be! As long as you have the right tools and materials—and follow safety protocols—you should have no problem restoring your steel surfaces to their former glory! Whether you choose mechanical methods such as sanding or grinding or opt for chemical solutions like phosphoric acid or citric acid, make sure you take steps afterwards to protect your surface against future corrosion for lasting results!
