Prep first
Before you start
- Check the pan's material before you pick a cleaner.
- Test any vinegar or cleaner on a hidden spot first.
- Never mix acid cleaners with bleach.
- Dry the pan fully before putting it away.
White marks on cookware are usually mineral deposits from hard water, left behind as the pan dries. Stainless steel handles a gentle clean and a soak well, but nonstick, aluminum and enameled pans need softer care, and chlorine bleach stays off stainless, nonstick and aluminum. Salt pitting is permanent, though it doesn't affect cooking.
Reach for a hard-water remover before anything abrasive, and rinse the pan fully once the spots loosen. Dry it right away, since water left sitting is what brings the spots back. If vinegar on pots doesn't shift the film, a scouring cleanser can finish the job, but only on stainless.

6 steps
Step by step
Step 1 of 6
Let the hot pan cool
Let a hot pan cool until it's only warm before it touches water. Cooling it first keeps the metal from taking a sudden temperature shock at the sink.
Careful. Never put a hot pan under cold water, or cold water into a hot pan; it can warp.
Step 2 of 6
Wash it in warm soapy water
Wash the whole pan in warm soapy water with a sponge or soft cloth. Rinse it well and look over the marked areas before going on.
Step 3 of 6
Boil equal parts vinegar and water
Pour in equal parts white vinegar and water, enough to cover the marked area, and bring it to a boil. Once it has boiled, take the pan off the heat and pour the liquid out.
Step 4 of 6
Rinse with clean water
Rinse the pan with clean water to clear away the vinegar. Check the marked areas in good light to see what's left.
Step 5 of 6
Scrub any marks that remain
Work a nonabrasive cleanser paste over the marks that remain, using a nylon scouring pad. Rinse thoroughly once the marks are gone.
Careful. Steel wool and steel scouring pads are off-limits on stainless.
Step 6 of 6
Dry it completely
Dry the pan fully with a clean towel before you put it away. Water left to dry on the metal is what leaves these marks in the first place.

Best products for white marks on pots, pans & bakeware
Look for a nonabrasive cleanser paste and a nylon scouring pad, the two product types that suit stainless steel.
The Pink Stuff Miracle Cleaning Paste
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on pots, pans & bakeware, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
A clean stainless pan looks even and bright, and water sheets off it rather than drying in chalky rings. If a dull haze or ring remains after the vinegar boil and the scrub, repeat the boil once before you try anything else.
What changes for yours
Adjust for your pots, pans & bakeware
Nonstick pans
Nonstick coating is damaged by abrasive cleaners, scouring pads and steel wool, so keep those out of the routine. Fill the pan with water and a squirt of dish soap, let it soak to loosen built-up residue, then wipe with a soft sponge.
The vinegar boil is only for stainless steel, so leave it out here. If a film remains after the soak, wipe it with a soft cloth and warm water rather than scrubbing harder.
Aluminum and non-stainless steel
These metals skip the vinegar boil, which is only for stainless steel. Wash them in warm soapy water with a soft sponge instead.
Bleach isn't safe on aluminum, non-stainless steel or chipped enamel. If you need to disinfect them, scald them instead, then dry them fully.
Enameled cast iron
Wash the enamel in warm soapy water with a soft sponge, and use no metal utensils on the surface. Keep citrus-based cleaners off the exterior.
A small amount of staining on enamel is to be expected, and it doesn't affect performance. If a mark bothers you, treat it as a cosmetic issue rather than scrubbing harder over it.
Hard-anodized pans
Hand wash hard-anodized pans in warm soapy water with a soft sponge, and keep them out of the dishwasher. Harsher cleaners aren't a fit for this finish, so skip the vinegar boil and any metal pad.
If a mark stays after washing, leave it alone rather than scrubbing harder, and check the cookware maker's directions for the finish first.
Heavy or long-standing buildup
Marks that have been on a pan for a long time are harder to shift than fresh ones. Start with the vinegar boil and the scrub in the steps above, then take a second pass before you try anything stronger.
If the mark has dried on through a hot cooking session, repeat the nonabrasive cleanser paste and let it soak before you scrub. Keep to a nylon pad, and rinse thoroughly afterward so no paste is left on the surface.
Long exposure above 500°F can change the color of stainless without hurting how it cooks, so a faint tint is cosmetic. If the mark still shows after repeated soaking and scrubbing, the pan will still perform as it should.
Vinegar, baking soda, peroxide and more
Do home remedies work on white marks on pots, pans & bakeware?
Most home remedies for white marks don't suit metal pans, so the steps lean on warm soapy water and white vinegar. On stainless and other cookware, warm soapy water and a vinegar boil handle most marks, and most other remedies don't suit metal.

What makes it worse
Mistakes to avoid
Don't use bleach or peroxide on stainless
Detergents containing bleach or peroxide aren't safe on stainless cookware, and chlorine bleach is out too. Oven cleaners are off-limits as well, so keep them away from the pan entirely.
Don't salt the water too early
Add salt only after the liquid boils or the food starts cooking. Salt added too early can leave white pits in stainless steel, and those don't go away.
Don't let a pan boil dry
Never leave an empty pan on a hot burner, and don't let a pan boil dry. Nonstick in particular must never overheat, so keep the flame moderate when you cook with it.
When to call a professional
If a white mark stays after these steps and a repeated soak, it may be damage in the metal rather than a deposit. A cookware maker can tell you whether the pan can be restored.
Questions
What causes white spots on stainless steel pans?
Most of them are mineral deposits left when water dries on the metal. Drying the pan fully after each wash is the simplest way to keep them from forming.
Can I use white vinegar on white spots on a pan?
Yes, on stainless steel. Boil equal parts white vinegar and water in the pan, pour it out, and rinse well.
Does baking soda remove white spots from pans?
Not for these marks. Baking soda in boiling water loosens burnt food, not this white film, so a vinegar boil works better on it.
Can I use a commercial descaler on my pans?
Check the cookware maker's directions first, since descalers can damage aluminum and other non-stainless metals. Descalers can damage aluminum and other non-stainless metals, so check the cookware maker's directions before using one on anything.
Are white pits from salt permanent?
Yes, salt pitting is permanent, but it doesn't affect cooking. The best protection is to add salt only once the water is boiling or the food has started to cook.
Will white marks on enameled cast iron affect cooking?
Not usually. A small amount of staining is expected on enameled cast iron, and it doesn't affect performance. Clean it only if the look bothers you.
Can I clean an aluminum pot with vinegar?
Keep vinegar for stainless steel and use warm soapy water and a soft sponge on aluminum. Dry the pot fully afterward so no water spots form.
