How to Remove Rust from Stainless Steel

To remove rust from stainless steel, use a mild acid plus gentle abrasion: spread a paste of two parts baking soda to one part lemon juice over the rust, leave 30 minutes, then wipe away with a damp sponge; or scrub with a sponge dipped in lemon juice then salt. For appliances, a cream-of-tartar-and-vinegar paste also works. Always rub with the grain, never use steel wool or wire brushes, and dry completely afterward to stop rust returning. Despite its name, stainless steel is an iron alloy, so it can rust — but it cleans up easily. Here’s how.

What causes rust?

Rust is the common name for iron oxide, a form of corrosion. Left untreated, it can weaken metal — pipes and appliances can lose strength and even leak. It shows up on stainless steel sinks, appliances, countertops, utensils, pans, pipes, and outdoor furniture, and is brought on by prolonged exposure to water, salt, oil, grease, or dirt (and sometimes manufacturing flaws).

Why does stainless steel rust?

Despite the name, stainless steel is an iron alloy, so it can rust when its protective surface layer is compromised:

• When items sit in water or aren’t dried properly.
• When something erodes the passive protective layer on the surface.
• With prolonged contact with salt, oil, or heat.

Properly cleaned and stored, stainless steel rarely rusts — but when it does, the methods below clear it up.

Supplies you’ll need

Most are everyday household items:

Some are used in combination — lemon juice with salt or baking soda, or cream of tartar with white vinegar.

How to remove rust from stainless steel appliances

Step 1: Mix a paste of two parts baking soda to one part lemon juice — thick enough to stay put (add baking soda if needed).
Step 2: Spread it over the rust on your fridge, stove, or sink.
Step 3: Leave 30 minutes, spritzing with water if it starts to dry out (you don’t want it crumbling off).
Step 4: Wipe away with a damp sponge — the rust should lift with it. Repeat if needed.
Step 5: Dry thoroughly with a clean cloth to prevent rust returning.

Alternative: mix ¼ cup cream of tartar with 1 cup white vinegar, let it sit on the rust 5 minutes, then gently scrub. The video below shows three lemon-based methods for a stainless sink, sprayer, and disposal.

How to remove rust from stainless steel utensils

Step 1: Wash the rusted items in warm soapy water first.
Step 2: Put lemon juice in one small dish and salt in another.
Step 3: Dip a corner of a clean sponge in the lemon juice, then into the salt.
Step 4: Gently scrub the rusted area until it disappears; repeat for stubborn spots.
Step 5: For ornate flatware with crevices, use a soft toothbrush dipped in lemon juice and salt.
Step 6: Rinse with plain water.
Step 7: Dry completely — a fan or hair dryer helps reach into patterned pieces — before storing, since any leftover moisture invites rust back.

How to prevent rust on stainless steel

Step 1: Avoid abrasive cleaners (like Ajax or steel-wool pads), and avoid bleach, ammonia, and alcohol-based cleaners.
Step 2: Never use wire scrubbers or wire brushes — they scratch the surface, creating spots where rust starts.
Step 3: Don’t leave stainless steel soaking in water overnight.
Step 4: Run the dishwasher’s drying cycle or leave the door open so items dry fully before you put them away.
Step 5: Dry your sink and appliances after use.
Step 6: Wipe up spills promptly.

Conclusion

Rust on stainless steel isn’t a reason to throw anything out. A mild acid (lemon juice, or cream of tartar with vinegar) plus gentle scrubbing lifts it, and drying everything thoroughly afterward — plus avoiding abrasives and wire brushes — keeps it from coming back.
