How to clean stainless steel the streak-free way

The short answer: how to clean stainless steel: wipe with mild soap and warm water on a soft cloth, going with the grain, then buff it dry.

• Polish with a stainless steel cleaner
• Keep away bleach, ammonia, chlorides and steel wool
• Rust spots: a baking soda paste
• Fingerprint-resistant finishes need their own care
• Next step: Plan it with the Cleaning Schedule ($4.49).

Here is how to clean stainless steel so it actually shines instead of streaking. Wipe with mild soap and warm water on a soft cloth, going in the direction of the grain, then buff it dry. Use a stainless steel cleaner for polish, and keep bleach, ammonia, chlorides and steel wool far away. This guide covers appliances, fingerprints, rust spots, fingerprint-resistant finishes, and the cleaning mistakes that cause dull patches.

How to clean stainless steel: the quick version

1. Find the grain, the faint lines running across the metal.
2. Wipe with a soft, clean cloth dampened in warm water and a little mild dish soap, along the grain.
3. Rinse with a cloth dampened in plain water.
4. Buff dry with a clean, dry microfiber cloth.
5. Polish (optional) with a stainless steel cleaner, again with the grain.
6. Treat rust spots with a baking soda paste or stainless brightener.

Why stainless needs gentle cleaning

Stainless steel resists stains, but it is not stain-proof. Consumer Reports quotes a GE Appliances quality manager who explains that the chromium in stainless forms an invisible layer that keeps moisture from reaching the iron. If that layer is breached or degraded, rust can form. Harsh cleaners and scratches are the most common ways the layer gets damaged, which is why the method matters as much as the cleaner.

What you need

Step 1: Find the grain

Brushed stainless has a direction, a pattern of fine parallel lines. On refrigerator doors it usually runs up and down. On dishwashers and range fronts it often runs side to side. Consumer Reports' cleaner tests say to always wipe in the direction of the metal's natural grain. Wiping in circles pushes grime into the lines and leaves swirl marks.

Step 2: Wash with mild soap

Consumer Reports' basic rule: wash stainless with mild soap, using a soft, clean cloth, then rinse and dry. Add a few drops of dish soap to warm water, dip a microfiber cloth, wring it out until it is just damp and wipe the surface along the grain. Start at the top and work down. Use a soft toothbrush on handles, seams and around buttons.

Use a fresh cloth. Consumer Reports says not to wipe stainless with a used dishrag, because it can contaminate the surface with food oils that can be acidic and harm the protective layer.

Step 3: Rinse and buff dry

Wipe again with a cloth dampened in plain water to remove soap, then buff dry with a clean, dry microfiber cloth. Consumer Reports says to buff the surface after cleaning. Drying is what prevents water spots and streaks.

Step 4: Polish with a stainless cleaner (optional)

Dedicated stainless cleaners remove greasy fingerprints and leave a shine. Consumer Reports tested eight sprays, wipes and aerosols and found some that cleaned well and left no streaks. It also notes that most stainless cleaners contain mineral oil, which helps shield the steel's protective layer. Spray it onto a microfiber cloth, wipe with the grain and buff.

Exception: fingerprint-resistant stainless. These finishes have a clear coating. Consumer Reports says stainless cleaners, acid-based cleaners and abrasives can scratch it. Use only a mild soap solution and a soft cloth.

How to remove rust from stainless steel

Small rust spots are treatable. Consumer Reports' options:

• A stainless cleaner or brightener, such as Bar Keepers Friend.
• A baking soda paste, applied with a soft cloth and rubbed gently with the grain. Samsung suggests 1 tablespoon of baking soda to 2 cups of water. Kenmore suggests equal parts.

Then rinse with clean water and a soft cloth, and dry. Follow your appliance brand's instructions first, or call its customer service line for model-specific advice. Keep an eye on spots you have treated, since they are more likely to rust again.

What never to use

Also check labels of cleaners you use nearby. Consumer Reports notes that Samsung warns the fumes alone from muriatic acid, found in some grout cleaners, can damage stainless steel.

Cleaning by appliance

Refrigerator. Handles collect the most fingerprints and food oils. Wipe them every few days with soapy water, then buff. Clean the door in vertical strokes if the grain runs up and down.

Dishwasher. The front panel and the top edge collect drips. Wipe and dry, paying attention to the controls on the top edge.

Range and oven. Let it cool completely. Wipe splatter from the front and backguard with soapy water. Heavy grease may need a second pass.

Microwave. Use the same soap-and-water method on the door, spraying onto the cloth so nothing drips into the keypad.

Sink. Stainless sinks get scratched by pots and stained by hard water. Rinse after use, wipe dry, and use a baking soda paste with the grain for spots. Our guide on how to clean a stainless steel sink has a full routine and stain fixes.

Stainless steel pots, pans and sinks

The same rules apply to cookware, with a little more scrubbing allowed on the inside of pans. Let a pan cool, then soak it in hot, soapy water to loosen stuck food. Scrub with a nonscratch sponge. For browned or rainbow-tinted spots from high heat, a baking soda paste or a stainless brightener usually lifts them; check the cookware maker's care instructions first. Dry pans right away so water spots do not form. Skip steel wool here too, since embedded fragments can rust.

Why some stainless rusts more than others

Not all stainless is equal. Consumer Reports reports that GE and KitchenAid say nonmagnetic grades, such as 304, which contains nickel, tend to be more rust-resistant than magnetic grades such as 430. Samsung and Bosch say all grades can rust if not properly maintained. Rust can also come from impurities embedded during manufacturing. So if a magnet sticks to your appliance, be extra careful with harsh cleaners and wipe spills promptly.

How often to clean stainless steel

Common mistakes

Wiping in circles. It leaves swirls. Go with the grain.

Too much water. Wet surfaces air-dry into spots. Wring the cloth and buff dry.

Using an all-purpose spray. Consumer Reports says stainless is not a surface on which you want to fool around with random multipurpose cleaners. Many contain ammonia or chlorides.

Skipping the dry step. Buffing is what makes it look clean.

Letting spills sit. Salty, acidic or sugary spills left on stainless can stain or wear the protective layer. Wipe them up the same day, then rinse and dry the spot.

Make it a weekly habit

Stainless looks great for about a day, then fingerprints win. A short weekly routine keeps it ahead.

Our Cleaning Schedule ($4.49) is a 9-page printable with daily, weekly and monthly checklists, a seasonal deep clean list, room-by-room checklists, a family chore chart and a cleaning supplies list. Put "wipe appliance handles" on daily, "wash and buff stainless" on weekly, and "stainless cleaner and microfiber cloths" on the supplies list.

For a whole-home system, the Home Management Bundle ($16.99) includes the Cleaning Schedule along with the Household Binder, Home Maintenance Log, Home Inventory, Moving Planner and Password & Accounts Log. Bought separately, those six come to $32.94.

A 2-minute daily wipe

Most stainless steel grime is fingerprints on handles and the area around them. Keep a dry microfiber cloth near the refrigerator, and wipe the handles and the most-touched spots once a day, following the grain. Do a full damp wipe with mild dish soap weekly, and save the stainless cleaner or polish for when the surface looks dull or streaky. Less product means fewer streaks.

Your next step

Grab two microfiber cloths and some dish soap. Find the grain on your fridge, wash one door with the grain, then buff it dry. Compare it with the other door. That is the routine; add it to your weekly list.
