Before you throw away rusty tools, try this aluminum foil cleaning method

Aluminum foil rust removal trick: Rust can make old tools and metal items look like they're ready for the trash, but a simple household item may be worth trying first: aluminum foil.

A cleaning hack has shown how a ball of regular aluminum foil can help remove surface rust from metal without the need for chemical cleaners. The method has been used on everything from rusty bathroom radiators to other metal surfaces around the home.

How to Remove Surface Rust With Aluminum Foil

The process is simple. Take a piece of aluminum foil and crumple it into a ball. You can use it dry, but professional cleaners suggest dipping the foil in water before rubbing it over the rusted surface, as per a Homes and Gardens report.


Rub the foil over the rust in a circular motion. If the aluminum becomes dry, re-wet it to keep the reaction going.

The method may require some elbow grease, especially when working over a larger area, but one benefit is that you can see the rust transferring onto the foil as you clean.

Once the surface rust has been removed, wipe the metal down with a clean, damp cloth. Then buff it with a dry towel.

Why Does Aluminum Foil Remove Rust

The science behind the trick is relatively simple. Rust forms when iron combines with oxygen, creating the familiar brownish-orange layer on a metal surface. When aluminum is rubbed against the rust, the aluminum loses electrons while the iron oxide gains them, turning back into metal, as per the Homes and Gardens report.

The aluminum acts as a reactive surface that helps remove the rust while also forming a layer of oxide.

According to cleaning experts, adding an acid such as vinegar or lemon juice can speed up the reaction, as per Homes and Gardens report. The foil can be dipped in the acid, or the item can be soaked when possible.

Can You Use Aluminum Foil on Other Metal Surfaces

Aluminum foil can also be used to help remove rust from metals such as chrome and steel. When cleaning chrome, one suggested method is to use foil dipped in a saline solution to help prevent scratching or discoloration.

For metal items without rust, aluminum foil can also be used with hot water and baking soda to create an electrolytic action that helps remove tarnish without harsh chemicals or extensive scrubbing.

When This Aluminum Foil Trick May Not Be Enough

Although aluminum foil can be a cost-effective way to tackle rust, the method is best suited to surface rust and staining. Deeply developed rust may require more specialist care.

So, before throwing away a rusty tool or metal item because it looks beyond repair, a piece of aluminum foil may be worth trying first. The simple method can help remove surface rust and improve the appearance of metal using something many people already have at home.
