The underside of pots and pans can become covered with burnt grease, food residue, black stains, and years of baked-on grime. Regular dish soap often isn’t enough, but with a few simple household ingredients and a little scrubbing, you can make a badly stained pan look dramatically cleaner.
What You’ll Need
- Baking soda
- Dishwashing liquid
- White vinegar
- A little warm water
- A non-scratch sponge or scrubber
- An old toothbrush for edges and difficult areas
- Rubber gloves
Step 1: Remove Loose Dirt
Place the pan upside down and rinse the bottom with warm water. Use a sponge to remove any loose grease, crumbs, or surface dirt.
Don’t worry if the bottom still looks black or heavily stained. The next steps are designed for the stubborn buildup.
Step 2: Make a Cleaning Paste
In a small bowl, mix:
- 3 tablespoons baking soda
- 1 tablespoon dishwashing liquid
- Enough warm water to create a thick paste
For particularly greasy areas, add a small amount of white vinegar to the mixture or apply the vinegar separately.
The paste should be thick enough to stick to the underside of the pan.
Step 3: Cover the Stained Areas
Spread the paste generously over the entire dirty underside, concentrating on areas with burnt grease and dark residue.
Let it sit for 15–30 minutes. If the buildup is extremely stubborn, you can leave the paste for longer, but don’t allow it to dry completely.
Step 4: Scrub Gently
Wet your sponge and begin scrubbing in small circular motions.
Work gradually rather than trying to remove everything at once. Pay particular attention to the outer edges, where grease often accumulates.
For grooves, seams, and corners, use an old toothbrush.
Step 5: Tackle Stubborn Burnt-On Grease
For areas that remain dark, sprinkle a little more baking soda over the surface and add a small amount of dish soap.
Scrub again with a suitable non-scratch pad.
You may need to repeat this process several times for years-old buildup. Heavy carbonized grease usually comes off much more easily when treated in stages rather than attacked with excessive force.
Step 6: Rinse Thoroughly
Once the residue has loosened, rinse the underside under warm running water.
Use a clean sponge to remove any remaining baking soda, grease, or cleaning mixture.
Step 7: Dry and Polish
Dry the pan completely with a clean towel. If the cookware has a stainless-steel exterior, you can finish with a small amount of white vinegar on a soft cloth to remove remaining water marks and leave the metal looking brighter.
Important: Check Your Pan Before Scrubbing
Not every pan should be cleaned aggressively.
For stainless steel, stronger scrubbing is generally more appropriate, although very abrasive materials can still scratch the finish.
For nonstick cookware, avoid abrasive scouring pads and harsh scrubbing, especially if the coating extends onto the underside.
For enameled cookware, use gentle cleaners and non-abrasive sponges to avoid damaging the finish.
For aluminum, test the cleaning method on a small inconspicuous area first because acidic cleaners can affect the appearance of the metal.
A Simple Maintenance Trick
The easiest way to keep the bottoms of your pans looking clean is to deal with grease before it becomes baked on. After cooking, allow the pan to cool, then wash away grease and food residue rather than letting it accumulate through repeated use.
With regular cleaning, you won’t have to spend nearly as much time fighting stubborn black buildup later.
