How to Clean a Burnt Pan Bottom (Outside and Inside)

The outside bottom of a pan takes the most heat and is often the hardest to clean. Grease, burnt drips, and carbon buildup accumulate over time and can be tough to remove. Here's how to tackle both the inside and outside of a burnt pan bottom.

What You'll Need

• Bar Keepers Friend Powder Cleanser — most effective product for burnt pan exteriors
• Amazon Basics Non-Scratch Sponges
• Baking soda and dish soap
• Warm water

Cleaning the Outside Bottom of a Pan

The exterior bottom accumulates the most stubborn burnt grease and carbon. This requires more effort than the interior.

Method 1: Bar Keepers Friend Paste

1. Mix Bar Keepers Friend powder with a small amount of water to form a thick paste.
2. Apply the paste to the burnt exterior bottom.
3. Let it sit for 5–10 minutes.
4. Scrub firmly with the scrubbing side of a non-scratch sponge.
5. Rinse thoroughly and repeat if needed.

Method 2: Baking Soda + Dish Soap Paste

1. Mix equal parts baking soda and dish soap into a paste.
2. Apply to the burnt bottom and let sit for 20–30 minutes.
3. Scrub with a sponge and rinse. Good for lighter buildup.

Cleaning the Inside Bottom of a Burnt Pan

For Stainless Steel

Use the boiling water + baking soda method first (fill with water, add 2 tbsp baking soda, boil 10 minutes), then finish with Bar Keepers Friend for any remaining stains.

For Non-Stick

Use only the boiling method — no abrasive cleaners. Fill with water and a drop of dish soap, simmer 5 minutes, cool, then wipe clean with a soft sponge.

For Cast Iron

Use a chain mail scrubber with coarse salt as a mild abrasive. Rinse, dry completely, and re-season.

How to Prevent Burnt Pan Bottoms

• Use the correct burner size for your pan
• Avoid cooking on excessively high heat
• Clean spills and drips from the exterior after every use
• Don't let pans sit on a dirty stovetop

Frequently Asked Questions

Can I use oven cleaner on a burnt pan bottom?

Oven cleaner works on some pan exteriors (especially stainless steel and enamel) but can damage non-stick coatings and aluminum. Use with caution and always test a small area first.

How do I remove years of burnt grease from a pan bottom?

For heavy buildup, apply a thick Bar Keepers Friend paste, cover with plastic wrap to keep it moist, and let sit for 30–60 minutes before scrubbing. Repeat as needed.

Why does the outside of my pan keep burning?

Using a burner that's larger than the pan base causes flames to lick the sides and bottom, creating carbon buildup. Match your burner size to your pan.
