How to stop aluminum corrosion

Updated February 21, 2017

Many metals rust or corrode, but the process can be stopped. Aluminium, used to make pots and pans, containers, flatware and other items used in the home, also falls victim to rust and corrosion. Once the protective rustproof coating on the aluminium wears off, that is when the metal is most prone to rusting. Cleaning aluminium regularly reduces or prevents rust formation. Removing small rust spots as they appear is crucial to stopping aluminium corrosion.

Scrub away any rust on the surface of the aluminium with a steel wool pad. Done regularly, small rust patches won't grow into more serious rust.

Apply a rust remover to the aluminium using a steel wool pad. Scrub the remover into difficult rust.

Leave the rust remover on the aluminium for five to 10 minutes. Rust removers work quickly because they are usually made of acids that dissolve the rust.

Wipe the rust remover off with rags or paper towels. Dampen a paper towel to remove any residue.

Paint on a rustproof primer for metals with a paint brush. The primer restores the protective coating that has worn off. The primer works as a barrier against the moisture that contributes to rust.

Tip

Wear rubber gloves when using the rust remover. Also make certain there is plenty of ventilation for protection against the fumes of the rust remover.

Warning

For aluminium pots and pans, do not add a primer to the metal.
