Stubborn black buildup on the bottom of a stainless steel pot can make a perfectly good piece of cookware look ruined. Before you replace it, try this simple kitchen method. It uses two common household items to make a thick paste that helps loosen burnt-on food with a little scrubbing.

What You’ll Need
Cleaning Paste Ingredients
- 3 tablespoons baking soda
- 1 tablespoon liquid dish soap (a degreasing dish soap works well)
- 1 to 2 teaspoons warm water, added slowly as needed
Tools
- A small bowl or glass measuring cup
- A spoon or small spatula
- A non-scratch sponge or soft scrub pad
- Warm water and a clean towel for rinsing and drying
Why This Method Can Help
Baking soda is a mild abrasive, so it gives you some gentle scrubbing power without the harshness of many commercial cleaners. Dish soap helps cut through grease that often bonds burnt food to the metal. Together, they form a paste that stays where you put it, which makes it easier to work on one spot at a time instead of rinsing everything away right away.
How to Make It
- Add 3 tablespoons of baking soda to a small bowl.
- Stir in 1 tablespoon of dish soap.
- Add warm water a little at a time, about 1 teaspoon, and mix until the texture looks like a spreadable paste. It should be thick enough to cling to the pot rather than run off.
- Check the consistency. If it is too runny, add a little more baking soda. If it is too dry to spread, add a few drops of water.
How to Use It
- Make sure the pot is cool enough to handle safely. Working on a warm pot can cause the paste to dry out quickly.
- Use a spoon to spread a generous layer of paste over the burnt area, covering the black residue fully.
- Let it sit for about 15 to 30 minutes. For heavier buildup, you can leave it a bit longer, but check it periodically so it does not dry out completely.
- Scrub gently with a non-scratch sponge or soft scrub pad, using small circular motions. Add a little water if the paste starts to dry.
- Rinse the pot with warm water to remove the paste and loosened residue.
- If some black spots remain, repeat the process on those areas rather than scrubbing harder.
- Wash the pot with regular dish soap, rinse well, and dry it completely.
What to Expect
This method works best on light to moderate burnt-on food. Very heavy, long-baked residue may need two or three rounds of soaking and scrubbing. Some faint discoloration can remain on stainless steel, especially if the pot was overheated for a long time. The goal is a cleaner surface that is easier to use again, not a brand-new finish.
Helpful Tips
- Soaking the pot with warm water for 10 to 15 minutes before applying the paste can make scrubbing easier.
- Use the paste on the outside bottom of stainless steel pots as well as the inside, since burnt residue often builds up there too.
- Scrub in the direction of the grain on stainless steel to help keep the surface looking uniform.
- Keep a few spare sponges handy, since a fresh one helps you scrub more effectively without leaving scratches.
Important Notes and Safety
- Do not use this method on nonstick cookware. Abrasive scrubbing can damage the coating.
- Avoid harsh metal scouring pads on stainless steel if you want to protect the finish, and never use them on nonstick surfaces.
- Do not mix baking soda paste with bleach or other cleaning chemicals. Combining products can create harmful fumes.
- Test the paste on a small hidden area first if you are unsure how your cookware will react.
- Store leftover dry baking soda in a sealed container away from moisture. Mixed paste should be used right away and not stored.
