- Let the pan cool, then scrape out the loose sauce.
- Rinse with warm water, never cold water into a hot pan.
- Don't rub the sauce around. Lift it out.
- Wash it the same day, before heat or drying sets it.
Tomato sauce leaves a red tint on cookware, and the oil in it gives the color something to cling to. Timing matters most here, because once the sauce bakes onto the bottom or sides, the residue is far harder to shift. Fresh residue clears much more easily than a crust that has been sitting on the metal.
Let the pan soak in warm water first so the crust softens before you scrub. For baked-on tomato, a baking soda boil loosens the crust, then a nonabrasive paste lifts the last of the red. Check the finish first, since an enamel Dutch oven or nonstick pan needs a gentler hand.

Step by step
Step 1 of 5
Cool the pan and scrape it out
Let the pan cool before you clean it. Then scrape out as much sauce as you can with a spoon or silicone spatula, without pressing it into the surface.
Careful. Never put cold water into a hot pan, or a hot pan under cold water; it can warp.
Step 2 of 5
Wash in warm soapy water
Rinse off any loose food with warm water, then soak the pan in warm soapy water. Wash it with a sponge or soft cloth, paying attention to the rim and the corners where sauce collects.
Step 3 of 5
Loosen any burnt-on sauce
If sauce has baked onto the bottom, sprinkle in baking soda, add water to cover it, and bring it to a boil. Loosen the softened sauce with a wooden spoon, then pour the water out.
Careful. Never let the pan boil dry or sit empty on a hot burner.
Step 4 of 5
Scrub with a pan-safe paste
On stainless, mix a nonabrasive, non-chlorine cleanser with a little water into a paste, then rub it in circles with a soft cloth or a nylon scouring pad. On nonstick, use baking soda and water on a non-abrasive sponge instead.
Tip. If the stain is stubborn, let the paste sit before you scrub again.
Careful. Steel wool and steel pads scratch stainless and nonstick.
Step 5 of 5
Rinse and dry right away
For cloudy white spots on stainless, boil 1:1 white vinegar and water in the pan first. Then rinse the pan with warm water and dry it immediately, so water spots don't form, and check the inside, rim and handle for any red film.

Best products for tomato sauce on pots, pans & bakeware
Choose a nonabrasive, non-chlorine cleanser for stainless, and a nylon scouring pad rather than steel wool. For nonstick, a non-abrasive sponge is the only scrubber you need.

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.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The pan is clean when a damp white cloth wiped over the surface comes away without any red color. On stainless, the finish should look even, with no cloudy patches or blue tint left.
What changes for yours
Adjust for your pots, pans & bakeware
Stainless with a blue or rainbow tint
That blue or rainbow tint is heat damage from overheating, not a stain you can scrub away. Wipe the tinted area with white vinegar on a soft cloth, then rinse and dry.
For cloudy white spots, use the vinegar-and-water boil from the drying step. For stainless appliances rather than pans, the Stainless Steel & Appliances guide covers those surfaces.
Stainless with burnt fat or protein shadows
Dark shadows from burnt fat or protein are the stubborn case on stainless. Repeat the cleanser paste and let it sit before you rub, instead of scrubbing harder.
Rinse and dry between rounds to see what's left. Stop once the remaining shadow no longer changes, rather than reaching for bleach, which stainless can't take.
Nonstick
Nonstick needs the gentlest approach, so keep to the baking soda paste on a non-abrasive sponge and skip any scrubbing pads. For residue that won't come off, fill the pan with water and dish soap and leave it overnight. Then wash it with a soft sponge and rinse.
If the coating still looks dull or sticky after that, use a cleaner made for nonstick surfaces rather than pushing harder with a pad.
Enameled cast iron
Enameled cast iron takes the same warm soapy wash, but its inside needs gentler tools. Use wood or soft tools, since metal utensils can damage the enamel, and skip citrus-based cleaners on the outside. For burnt sauce, use 2 cups water with 4 tablespoons baking soda and a pan scraper instead of a spoon.
A small amount of staining is expected on enameled cast iron and doesn't affect how it performs. If the inside still looks dark after these steps, move to the set-in soak below.
Aluminum or non-stainless steel
Leave the baking soda boil out on aluminum, since baking soda is listed as unsafe for it. Use the warm soapy wash with a sponge or soft cloth, and skip any bleach.
To disinfect these pans, scald them instead of using bleach. Non-stainless steel pans get the same treatment.
Old, dried or set-in stains
Old tomato stains on enameled cast iron can outlast a normal wash, especially once the sauce has dried in the pan. Stainless can hold faint shadows that the cleanser paste only partly lifts. Heat and drying are what make these stubborn, so the sooner you start, the better.
For enameled cast iron that still looks stained inside, rinse the pan out completely, then soak it for 2 to 3 hours in equal parts white vinegar and warm water. Household bleach isn't an option on this cookware, since it can't take chlorine.
Skip this soak if the enamel is chipped, and rinse the pan well when it's done. Stainless and aluminum pans don't get this soak.
On stainless, repeat the cleanser paste and let it soak before you scrub again. Some shadows will still fade only partly, and that's realistic. Salt pits are permanent, and a small amount of enamel staining doesn't affect cooking, so you can stop there.
Vinegar, baking soda, peroxide and more
Do home remedies work on tomato sauce on pots, pans & bakeware?
Plenty of kitchen remedies circulate for sauce, but many don't suit cookware or can damage the metal or coating. Gentle washing works for most pans, a pan-safe paste only suits some, and chlorine bleach stays off cookware.

What makes it worse
Mistakes to avoid
Don't let the sauce dry on
Heat and drying set tomato stains, so a pan left to dry with sauce on it is much harder to clean. Wash it the same day, even if you only rinse it at first.
Don't mix vinegar, peroxide or bleach
Don't combine hydrogen peroxide, vinegar or lemon juice with each other, or with chlorine bleach or ammonia. Use one, rinse thoroughly, then move on to the next.
Don't put hard-anodized pans in the dishwasher
Hard-anodized pans shouldn't go in the dishwasher, so wash them by hand in warm soapy water instead. The hand-wash steps above work for these pans.
Don't use oven cleaner on stainless
Oven cleaners, harsh detergents, and detergents with bleach or peroxide are all off limits on stainless cookware. Stick to the cleanser and rinse routine above.
When to call a professional
Professional cleaning isn't needed for cookware if the wash and soak work. If a stain stays after the steps and the set-in soak, stop there rather than trying stronger cleaners.
Questions
Does tomato sauce stain ceramic cookware?
It can leave a red tint, and the stain sets fast once it dries or gets heated. Until you've checked the care label, use only warm soapy water and wash the pan the same day.
Can I use bleach on my pan?
Only on enameled cast iron, and only as the set-in soak. Stainless, aluminum and other non-stainless steel can't take bleach at all.
What causes the blue or rainbow tint on stainless?
The tint comes from overheating the pan, and it's a heat mark rather than a stain. Wipe it with white vinegar on a soft cloth, then rinse and dry.
Can I use baking soda on aluminum pans?
No, baking soda is listed as unsafe on aluminum, so skip the boil. Wash with warm soapy water and a soft cloth, and scald the pan if you need to disinfect it.
How do I get rid of white spots on stainless?
Boil equal parts white vinegar and water in the pan, then rinse and dry right away. Drying the pan immediately is the habit that keeps spots from forming.
Does salt damage stainless pans?
Salt can leave white pits on stainless, and the pitting is permanent but doesn't affect cooking. Add salt only after the liquid boils or the food starts cooking to avoid it.
Why does my nonstick still feel sticky after washing?
Built-up residue can do that, so fill the pan with water and dish soap and leave it overnight. Then wash it with a soft sponge and rinse well.
