Rust is a reddish brown layer of iron oxide that forms when an object containing iron is exposed to oxygen and water, like moisture in the air. In humid climates and near the ocean, rust is likely to form on tools, door hinges, and even metal clasps and fittings. Here are several easy tips on removing rust stains and rust itself from your household objects and clothing.
How to Remove Rust & Rust Stains
With all the tips below, test any products you use on a small area of your surface or material first, and always read product labels to ensure that you are using them properly. Remember to rinse your object or cloth with clean water after you’ve removed the rust and allow it to dry fully.
Commercial rust removers
There are a number of commercial rust remover products and they often work differently, so be sure to read the instructions carefully. These products can be very powerful, so you will most likely need to wear gloves and use them in a well-ventilated space, as the fumes can be dangerous.
White vinegar and salt
This is one of the most popular solutions, the idea being that vinegar will dissolve the rust off the metal.
- To remove rust from small objects, soak them in a bowl of white vinegar for up to 24 hours.
- When dealing with larger objects, pour a layer of vinegar over the rust and then add a layer of salt, or dip aluminum foil in vinegar and use it like a brush to scrub off the rust.
- To remove rust stains on fabric, saturate the stain completely with white vinegar, cover it in a layer of salt, and then gently rub the salt in. Let the stain soak for a few hours and then blot or rinse the rust away.
Lemon or lime juice and salt
A simple recipe that’s not as harsh as vinegar.
- Cover the rust or rust stain in salt, then fully saturate it with lemon or lime juice. Mix the juice and the salt together, and let it soak for a few hours.
- To clean white clothing, lay the fabric out in direct sunlight for up to 60 minutes, which should remove the stain.
- With metal objects, use the rind of the lemon or lime to scrub away the rust afterward.
