If you mean an ingredient that can quickly remove burnt stains (black, stuck-on food) from pots and pans, the most effective common household ingredients are baking soda and white vinegar. They do not “instantly erase” a severe burn, but they can loosen and lift burnt layers when used correctly.

1. Baking soda (Sodium bicarbonate) — best overall for burnt cookware

Why it works:

• Baking soda is a mild alkaline cleaner.
• It helps break down grease, oils, and carbonized food residue.
• Its fine particles provide gentle scrubbing without being as harsh as many abrasives.

How to use it:

1. Add enough water to cover the burnt area of the pot or pan.
2. Add 2–4 tablespoons of baking soda.
3. Bring the mixture to a gentle boil for 10–15 minutes.
4. Turn off the heat and let it cool slightly.
5. Scrub with a sponge or non-scratch brush.
6. Repeat if the burn layer is thick.

Best for:

• Stainless steel pots
• Aluminum pans (use gently)
• Enamel cookware

2. White vinegar (Acetic acid) — helps dissolve mineral and food deposits

Why it works:

• Vinegar contains acetic acid, which reacts with alkaline residues and helps soften stuck deposits.
• It can loosen burnt food films when combined with heat.

How to use it:

1. Pour enough white vinegar to cover the burnt area.
2. Heat it for a few minutes (do not boil aggressively).
3. Let it sit for 15–30 minutes.
4. Add baking soda after cooling for extra fizzing action.
5. Scrub and rinse.

Best for:

• Stainless steel
• Glass cookware

3. Dish soap + hot water — for fresh burns

Why it works:

• Hot water softens food proteins and starches.
• Soap breaks down oils.

Method:

• Fill the pan with hot water.
• Add a few drops of dish soap.
• Leave for several hours or overnight.
• Scrub afterward.

4. Lemon juice — natural mild acid

Why it works:

• Citric acid helps loosen stains and adds cleaning power.
• It also removes odors.

Method:

• Add lemon slices and water.
• Simmer for 10–15 minutes.
• Let cool and scrub.

5. Salt — for gentle scrubbing

Why it works:

• Salt crystals provide mild abrasion.
• It can help remove softened burnt particles.

Method:

• Sprinkle salt on the wet surface.
• Scrub gently with a sponge.

Stronger method for very badly burnt pans

Baking soda + vinegar + boiling method:

1. Add a layer of water to the pan.
2. Add ½ cup white vinegar.
3. Simmer for 5–10 minutes.
4. Turn off heat.
5. Add 2–3 tablespoons baking soda (it will foam).
6. Wait 15 minutes.
7. Scrub.

Important cautions

• Do not use vinegar on natural stone surfaces or some reactive metals for long periods.
• Avoid harsh scrubbing on non-stick pans because it can damage the coating.
• Never mix vinegar with bleach — it can create dangerous chlorine gas.
• For copper cookware, use specialized methods because acids can affect the finish.

For the fastest household solution, use baking soda + hot water + gentle boiling; it is usually the most reliable way to loosen burnt food from pots and pans.
