Flip your pan over and you’ll probably find a dark, scorched ring on the outside bottom, sometimes crusty, sometimes greasy and sticky. This happens from heat hitting the underside directly, especially on gas stoves where flames wrap slightly around the edges, baking on drips and residue that never even touched your food.
The good news is the outside of a pan can usually take a bit more scrubbing than the inside, since it’s rarely coated the way cooking surfaces are. This guide covers a baking soda method for regular buildup, and a soak-based approach for grease that’s been baked on for a long time.
At a Glance: Which Method Do You Need?
- Moderate scorching or grease? A baking soda scrub cuts through it. Head to Method 1.
- Old, thick, blackened buildup? A longer soak loosens it before you scrub. Head to Method 2.
Not sure which one you need? Start with Method 1, it’s quicker and handles most everyday scorching just fine.

Method 1: Baking Soda Scrub (For Regular Scorching)
Since the outside of most pans is bare metal rather than a non-stick coating, a bit of gentle abrasion here is safe and actually necessary to cut through scorched residue.
What You’ll Need
- Baking soda
- Warm water
- A scrub sponge or nylon brush
- A cloth for drying
A sturdy nylon brush works well here, stiff enough to cut through scorching without scratching stainless steel.
How to do it:
Step One: Wet the bottom of the pan under warm water so the baking soda has something to stick to.
Step Two: Sprinkle baking soda generously over the scorched area, or mix it with a small amount of water first to form a thicker paste for heavier spots.
Step Three: Let it sit for 10 to 15 minutes so it has time to start breaking down the residue.
Step Four: Scrub in circular motions with a sponge or nylon brush, adding more baking soda as needed if the paste thins out.
Step Five: Rinse thoroughly and check the surface, if some spots are still dark, repeat the process rather than scrubbing harder in one spot.
Step Six: Dry completely with a clean cloth to avoid water spots on stainless steel.
Method 2: Vinegar Soak (For Old, Blackened Buildup)
Use this when the scorching has clearly been there a long time and baking soda alone isn’t lifting it. Soaking loosens the buildup first, so you’re not fighting it with pure scrubbing power.
What You’ll Need
- White vinegar
- Warm water
- A basin or sink large enough to submerge the pan
- Baking soda
- A scrub sponge or nylon brush
A distilled white vinegar works well for this soak, it’s inexpensive and effective at loosening old, blackened residue.
How to do it:
Step One: Mix one part white vinegar to two parts warm water in a basin or sink large enough to fully submerge the bottom of the pan.
Step Two: Let the pan soak for 20 to 30 minutes, upside down or fully submerged, whichever fits your sink better.
Step Three: Remove the pan and sprinkle the scorched area with baking soda while it’s still wet.
Step Four: Let it sit for another 10 minutes, this combination targets buildup that a quick scrub alone usually can’t touch.
Step Five: Scrub with a sponge or nylon brush, rinsing and reapplying baking soda if needed for stubborn spots.
Step Six: Rinse the entire pan thoroughly and dry completely with a clean cloth.
A Quick Note on Pan Materials
Stainless steel handles both of these methods well and can take a fair amount of scrubbing. Cast iron exteriors can also be scrubbed, but avoid soaking them for long periods, prolonged water exposure can lead to rust. Non-stick pans with a coated exterior are rare, but if yours has one, skip the abrasive scrub and stick to the vinegar soak with a soft sponge instead.
A Quick Habit That Helps a Lot
Wiping the bottom of the pan with a damp cloth once it’s cooled, especially after cooking something greasy or messy, keeps scorching from building up layer after layer. Most of what ends up as heavy, blackened buildup started as something that could have been wiped away in seconds.
Whichever method you use, the idea stays the same, loosen it first, then scrub gently. Stay on top of wiping the bottom after cooking, and you’ll rarely deal with heavy scorching at all.
