If you don’t know how to remove rust from stainless steel, then it’s time you learned. Rust will destroy your stainless steel pots, for example, if you let it. Once you learn how to eliminate rust, you’ll be one step closer to becoming a DIY home improvement expert.
Corrosion is a natural process that occurs in moist environments. Chemically active metals become corroded while rusting is a process where iron corrodes due to atmospheric exposure. This is how stainless steel appliances accumulate rust.
According to researchers at the University of Georgia, “There are chemical gels on the market that break down rust so it dries and hardens into a smooth protective base like a primer coating. Then the surface can be painted. Read all labels and precautions carefully.”
Why Does Stainless Steel Rust?
Rust is caused by the reaction to iron, and other metals, have when it comes into contact with oxygen and water. The Achilles heel for stainless steel surfaces is moisture. It’s a hotspot for rust to develop and can ruin tools, utensils, and structures.
Removing rust from stainless steel appliances requires serious cleaning power. While the item might be too far gone, what you need is the right cleaning products to remove rust without damaging your surfaces or stainless steel utensils.
DIY Rust Removal Solutions
There are many ways to remove difficult rust spots from stainless steel. We’re going to show you a few DIY stainless steel cleaners you can use. We’ll also provide simple steps you can take to remove rust from stainless steel appliances without damaging them.

Frequently Asked Questions (FAQ)
What Is A DIY Way To Remove Rust From Tools?
When removing rust from knives and hand tools, just soak them in vinegar overnight. Pour vinegar into a plastic bucket and place the rusty items in it. Remove the items and scrub them gently with a wire mesh brush or something similar. After, rinse the items with water and use a clean cloth to dry them.
What Is Passivation Of Stainless Steel?
Passivation is the process of enhancing stainless steel surfaces with a chemical treatment to safeguard against corrosion. The process also helps remove contamination.
What Is Dry Ice Blasting?
Also known as cryogenic blasting, this cleaning uses compressed frozen carbon dioxide, or dry ice, and sublimates under high pressure on a rusted surface. After, a high-pressure power jet blasts the ice, at a temperature of -79° C, onto your contaminated stainless steel surface. Because the stainless steel surface is warm, it creates a “thermo shock,” loosening the rust while the dry ice evaporates.
How To Remove Rust From An Iron Skillet?
Removing from an iron skillet requires a mixture of white vinegar and equal parts water. Pour the mixture in a plastic bucket and let your skillet soak in it for eight hours. After, wash it off and clean cloth.
Can You Remove Rust With A Laser?
Laser rust removal is designed to clean industrial metal parts. Fiber lasers can remove rust and contaminants without causing permanent damage to the metal or stainless steel surface.
Remove Rust From Stainless Steel Conclusion
While there are many ways to remove rust, when working with stainless steel surfaces you will need to be extra careful. You’ll need to make sure you know what kind of metal your surfaces are made out of and if they have a protective coating that can be removed.
When cleaning, use mild substances with soft formulas. When tackling deep pitting, don’t hesitate to use an old toothbrush, wire brush, or brush attachment on an electric drill. Then sand down to bare metal with a medium-grit silicon carbide paper.
With hard to sand surfaces, brush off as much rust as possible with a clean cloth. After this, apply naval jelly, a commercial gel-like rust remover, and watch your rust problems go away.
