Stainless steel is a popular material for appliances, counters, and sinks because it is durable and affordable. However, despite its “stainless” name, rust can still form on stainless steel if it is not properly cared for.

Causes of Rust on Stainless Steel

Rust forms on stainless steel when the protective chromium oxide layer is damaged, exposing the underlying iron to oxygen and moisture. This can happen in a number of ways, including:

• Exposure to corrosive elements like salt and chlorine
• Deep scratches or gouges
• Contact with rusty objects, such as a wet cast iron pan
• Harsh cleaning products or tools

Homemade Rust Removers for Stainless Steel

If you find rust on your stainless steel, don’t panic! You can remove it using a few simple household items:

Baking Soda:

• Wet the rusty area and sprinkle it with baking soda.
• Let it sit for 30 minutes.
• Gently scrub away the rust with a damp sponge, following the grain of the stainless steel.
• Rinse and dry the area.

Raw Potato:

• Cut a raw potato in half.
• Put a few drops of dishwashing liquid on the cut sides.
• Rub the rusty area with the potato, following the grain of the metal.
• Let it sit for at least four hours.
• Remove the potato and wash the area well with a sponge.
• Rinse and dry the stainless steel.

Cream of Tartar and Vinegar:

• Make a paste with one-fourth cup of cream of tartar and one cup of distilled white vinegar.
• Cover the rusty area with the paste and rub it in with a sponge, following the grain.
• Let it work for at least five minutes and then rinse it away.
• Dry the area and repeat if needed.

Lemon Juice and Salt:

• Make a paste by mixing two parts of table salt and one part of lemon juice.
• Or, dip the cut end of a lemon in table salt.
• Apply the paste to the rust area with a sponge and gently scrub away the rust, following the grain.
• Rinse the cleaned area with warm water and dry with a clean cloth.

How to Prevent Rust on Stainless Steel

To prevent rust from forming on your stainless steel, follow these tips:

• Avoid using steel wool or wire brushes for cleaning, as they can scratch the surface and make it more susceptible to rust.
• Use mild cleaning products and avoid harsh chemicals like chlorine bleach, ammonia, mineral spirits, or alcohol-based cleaners.
• Do not leave stainless steel cookware and utensils soaking in water overnight.
• Dry sinks after each use and clean up spills immediately to minimize excessive moisture.
• Regularly clean and shine stainless steel surfaces with a stainless steel cleaner.
• Keep stainless steel appliances in a dry, conditioned space.

Additional Tips for Removing Heavy Rust

If the rust on your stainless steel is particularly heavy or stubborn, you may need to use a commercial rust remover. Look for products that contain oxalic acid, such as Bar Keepers Friend. Follow the label directions carefully when using these products.

You can also try using a rust eraser sponge. These sponges are made of melamine foam, which is a very abrasive material. They can be effective at removing rust, but they can also scratch the surface of the stainless steel. Use them with caution.

If you are unable to remove the rust yourself, you may need to consult a professional.
