Rust is tough, but you can get rid of it on most surfaces. To prevent rust from forming you should keep metals dry and minimize their exposure to humidity and water. Here’s an overview of your options for treating and preventing rust on most common objects.
Step One
Put on rubber gloves.
Step Two
Treat the affected material (metal or otherwise) with a rust-removing agent that contains oxalic acid, taking care to follow instructions on the product label.
Step Three
Treat severe rust stains (especially in toilet bowls) with a pumice scouring pad along with the rust-removing agent.
Step Four
Prevent indoor metal items from rusting by keeping their surfaces dry, dusting regularly and wiping down occasionally with a damp cloth. Dry immediately after wiping down.
Step Five
Keep outdoor wrought-iron structures rust-free by removing existing rust with a wire brush, some sandpaper or a sandblaster. Then go over bare spots with rust-inhibiting primer and paint the surface with rust-resistant metal paint.
