How to Remove Rust from Stainless Steel: Tips for a Sparkling Finish

Cleaning rust off stainless steel surfaces is often associated with commercial solutions containing potentially harmful chemicals. These solutions, like those with phosphoric acid, can effectively remove rust but may pose risks, especially upon skin or eye contact.

Here are five safe and household-friendly methods to remove rust from stainless steel surfaces, suitable even when kids are around (though it’s advisable to keep these solutions away from children):

Method 1: Baking Soda and Water

Baking soda, a natural mineral with mild alkaline properties, is a gentle abrasive that won’t scratch stainless steel. It reacts with water to produce carbon dioxide bubbles, effective in lifting stains.

  • For small rust spots, create a paste by combining 1 tablespoon of baking soda with 2 cups of water. Apply the paste to the rusted area, rub gently with a soft cloth, then rinse and dry.
  • For larger rusted areas, dampen the surface, sprinkle baking soda generously, let it sit for 30 minutes to an hour, scrub with an old soft-bristled toothbrush, and finish by rinsing and drying.

Method 2: Cola or Root Beer

Cola and root beer contain phosphoric and citric acid, which can break down rust. While not as concentrated as commercial rust-cleaning solutions, they are often effective.

  • For small rust spots, dip a cloth or toothbrush in cola or root beer, buff the rusted area, then rinse thoroughly.
  • Alternatively, use aluminum foil with cola or root beer for chrome surfaces, acting as a mild abrasive for stubborn rust.
  • For larger surfaces with rust, soak the item in cola or root beer overnight before scrubbing with a soft cloth, aluminum foil, or an old toothbrush. Remember to rinse thoroughly after scrubbing.

Method 3: Cream of Tartar and Lemon Juice

Suitable for: Items with moderate rust stains

Cream of tartar, readily available in the baking section, is an affordable option. Mix 1 tablespoon of cream of tartar with a few drops of lemon juice to create a thick paste for rusty spots. Apply the paste using a soft sponge, buff over the rust, then wipe it off with a damp sponge. Make sure to use a soft sponge to avoid surface damage.

Method 4: Lemon Juice and Baking Soda

Suitable for: Items with moderate rust stains

This tried-and-true method involves mixing equal parts baking soda and lemon juice into a thick paste. Apply the paste generously over rusted areas and use a damp sponge to remove the rust. If necessary, reapply the paste and let it sit for 30 minutes before scrubbing again. Optionally, you can use lime juice or hydrogen peroxide instead of lemon juice.

Method 5: White Vinegar

Suitable for: Slightly rusted items

White vinegar, containing acetic acid, serves as a mild corrosive cleaner effective against mild rust, dirt, and stains. This method may not work on stubborn rust and is not recommended for use on oil-repellent stainless steel. Fill a spray bottle with undiluted white vinegar, spray it on the item, wipe it off with a cleaning cloth or paper towel until dry, and finish with a water rinse.

Tips for Cleaning Rusty Stainless Steel

If it’s your first time using these methods, take precautions to avoid damage:

  • Do a “patch test” in an inconspicuous area before applying the solution to the entire surface.
  • Avoid scouring powder and metal abrasives; opt for a microfiber cloth or an old toothbrush.
  • Check cleaning supplies for chlorides, as they can be abrasive and cause discoloration.
  • Clean in the direction of the grain to prevent accumulation of dirt in crevices.
  • Rinse the surface thoroughly after rust removal, and ensure it’s completely dry before storing.

How to Prevent Stainless Steel from Rusting

Prevention is key, and these tips will help maintain your stainless steel:

  • Clean spills immediately to prevent water stains and rust.
  • Wipe away fingerprints daily using warm water and dish detergent or hand soap, followed by drying with a paper towel.
  • Use RP7, a multi-purpose spray, periodically on stainless steel surfaces to lubricate, prevent rust, and repel moisture. Adjust the frequency based on material type and environmental conditions.
