How to remove rust from metal: home methods and lasting protection

Rust forms when iron reacts with moisture and oxygen. If noticed early, it can usually be cleaned at home.

Light rust

White vinegar, or a mixture of lemon and salt, softens light rust. Apply it to the surface, leave it for a while, scrub with a soft brush, rinse with plenty of water and be sure to dry it.

Widespread rust

For deeper rust, fine sandpaper or a wire brush is used. Commercial rust removers are also available; follow the manufacturer's instructions and wear gloves.

Rust stains on stainless steel

Orange stains on stainless steel most often come not from the steel itself but from iron particles or chlorine-containing products that have settled on the surface. Wiping with a damp cloth and a stainless steel cleaner is usually enough. If the stain keeps coming back, the grade or the environment should be questioned (for example salt, chlorine).

Keep it from rusting again

• Dry the surface after cleaning
• Apply protective paint, oil or polish to carbon steel surfaces
• In damp environments, prefer stainless steel or a suitably coated material
