Proven Ways: How to Get Soot Out of Instant Pot Fast

By Tom Bradley · November 9, 2025

Immediate Action (first 5 minutes)

Unplug the machine. Seriously, do it right now. You don't want to risk a shock while dealing with conductive carbon buildup, and waiting three extra minutes won't ruin your cleaning timeline. I've seen too many people fry their motherboard because they started wiping down a wet heating element while it was still plugged in.

Grab a dry paper towel. Wipe away any loose, powdery black dust before it gets wet. If you add water to dry soot, you'll just create a stubborn, muddy paste that smears right into the brushed stainless steel finish of your Instant Pot Duo 6-Quart.

Let the unit cool down to room temperature, which usually takes about 15 to 20 minutes. If you were pressure cooking a massive batch of chili for a Super Bowl party and it sputtered everywhere, the outer rim might still be dangerously hot. Touch the lid gently. Once it's cool, move the pot to a well-lit area so you can actually see the damage. Soot isn't just dirt. It's carbonized food and burned oils baked onto the metal at high temperatures. Treating it like a normal spill will only frustrate you.

What You'll Need (tools/products)

I've tested dozens of cleaners on my own appliances over the last decade. Soot requires specific degreasers and mild abrasives to break those tough chemical bonds without scratching the metal. Here is my exact toolkit for this job. You don't need to buy expensive specialty chemicals. Most of these items are probably sitting under your kitchen sink right now.

Bar Keepers Friend Soft Cleanser ($5-8 for a 13 oz bottle). This is my absolute favorite. The liquid version contains oxalic acid, which chemically breaks down carbon bonds much faster than the powder. It's less messy and doesn't leave gritty residue in the crevices of your lid.

Dawn Powerwash Dish Spray ($6-10 for a 16 oz spray). Regular dish soap just doesn't cut through burned-on grease. This spray has built-in solvents that cling to vertical surfaces, making it perfect for the exterior walls of the cooker.

Mr. Clean Magic Eraser Extra Durable ($12 for a pack of 8). These melamine sponges act like ultra-fine sandpaper. They physically lift the soot out of the microscopic grooves in the stainless steel.

Microfiber Cleaning Cloths ($15 for a 12-pack). Don't use paper towels for the final wipe. They just leave white lint behind that sticks to the wet metal.

Let's compare the heavy hitters so you know exactly what to grab first.

Product	Best For	Price Range	Scrubbing Effort
Bar Keepers Friend Liquid	Exterior stainless steel	$5 - $8	Low
Dawn Powerwash	Greasy outer shell	$6 - $10	Very Low
Magic Eraser	Stubborn crusts	$12 (8-pack)	Medium
Baking Soda Paste	Inner aluminum pot	$2 - $4	High

Step-by-Step Removal

Step 1: Dry Wipe the Exterior

Take your dry microfiber cloth and wipe down the entire outside of the unit. You want to remove any loose ash or food particles. If you skip this, you'll just grind the hard carbon chunks into the metal when you start scrubbing. Pay special attention to the seam where the lid meets the base.

Step 2: Degrease the Outer Shell

Spray the Dawn Powerwash directly onto the soot-stained exterior. Let it sit for exactly 3 minutes. You'll see the spray start to turn brown as it dissolves the burned oils. Wipe it away with a damp microfiber cloth. This won't remove the hard black crust, but it removes the greasy top layer so your abrasive cleaner can actually reach the stain.

Step 3: Apply the Oxalic Acid Paste

Shake your Bar Keepers Friend Soft Cleanser well. Apply a generous layer directly over the remaining black soot marks. I usually use about two tablespoons for a heavily stained 6-quart model. Use your fingers or a soft silicone spatula to spread it evenly over the affected areas. Let it sit for 5 minutes. Don't let it dry out completely.

Step 4: Scrub with Melamine

Wet your Magic Eraser and squeeze out the excess water. Scrub the soot stains using firm, circular motions. I'll be honest, this takes elbow grease. You might need to scrub for 4 to 5 minutes on really bad burns. The black soot will transfer onto the white sponge. Rinse the sponge frequently in the sink to expose a fresh cleaning surface.

Step 5: Clean the Anti-Block Shield and Silicone Ring

Soot loves to hide in the lid components. Pop off the anti-block shield (the little metal cap on the underside of the lid) using a butter knife. Wash it in warm soapy water. If your silicone sealing ring smells like burned chili, soak it in a bowl of white vinegar and water for 30 minutes. This neutralizes the trapped carbon odors.

Step 6: Rinse and Dry Thoroughly

Wipe away all the Bar Keepers Friend residue with a clean, wet cloth. You might need to rinse your cloth three or four times. Once the metal looks clean, dry it immediately with a fresh towel. Air drying will leave hard water spots that look just like soot stains.

Alternative Methods

Sometimes you don't have the right products on hand, or the soot is baked onto the inner aluminum pot rather than the stainless steel exterior. Here are two backup methods I use when my main supplies run out.

Method 1: Baking Soda and Vinegar Boil

This is the classic internet hack, but I'll be honest, it takes serious elbow grease for heavy soot. Fill the inner pot with 2 cups of water and 1 cup of white vinegar. Run the Instant Pot on the 'Steam' setting for 10 minutes. Carefully release the pressure, dump the liquid, and then scrub the inside with a paste made of baking soda and water. The heat helps loosen the carbon, but you'll still need to scrub hard with a non-scratch sponge. This isn't the fastest option, but it uses cheap pantry staples.

Method 2: Heavy Duty Oven Cleaner

If you have a massive, rock-hard soot crust on the exterior base that nothing else will touch, grab a can of Easy-Off Heavy Duty Oven Cleaner ($8-12). Spray it on the cold, unplugged exterior base. Let it sit for 15 minutes. The lye in the oven cleaner will literally melt the carbonized food into a slimy brown sludge. Wipe it away with paper towels. You must wear rubber gloves for this. Never use this on the inner aluminum pot or the heating element, as lye will permanently pit and ruin aluminum.

Prevention Tips

Cleaning soot is a pain. Preventing it is incredibly easy if you follow a few basic rules. I've managed to keep my own machines spotless for years by sticking to these habits.

Respect the Max Fill Line

Never fill the inner pot past the 'PC Max 2/3' line. When cooking foods that expand or foam like beans, oats, or chili, stay below the '1/2' line. Soot happens when starchy bubbles boil up, hit the steam release valve, and spray carbonized liquid all over the hot exterior.

Clean the Steam Release Valve Weekly

Pull the black steam release handle straight up to remove it. Wash it in the sink. Food particles get trapped inside the little pipe, burning into hard black soot every time you cook. A quick rinse prevents this buildup entirely.

Check Your Sealing Ring

If your silicone ring is cracked, warped, or stretched out, your pot will leak steam continuously. That leaking steam carries microscopic food particles that bake onto the side of the machine. Replace the ring every 12 to 18 months. They cost about $10 for a two-pack on Amazon.

Use a Splatter Guard

When you are doing a quick release on messy foods, place a silicone splatter guard or a folded paper towel over the valve. This catches the starchy spray before it hits the metal body. It's a simple trick that saves you 20 minutes of scrubbing later.

FAQ

Can I put the inner pot in the dishwasher to remove soot?

Yes, the stainless steel inner pot is completely dishwasher safe. However, the dishwasher won't remove thick, baked-on soot crusts on its own. You should manually scrub the worst spots with Bar Keepers Friend before loading it into the machine, otherwise you'll just bake the carbon on even harder during the heated dry cycle.

Why is my Instant Pot leaving black marks on my kitchen counter?

Those black marks are usually a mix of condensed steam, microscopic food particles, and soot dripping from the bottom rim. If you see this, your outer base is dirty, or your anti-block shield is clogged. Wipe down the bottom edge of the cooker with a degreaser after every single use to stop the transfer.

Is soot dangerous to cook with if I don't get it all off?

A few tiny specks of carbon on the exterior won't hurt you, but thick soot inside the inner pot can impart a bitter, acrid taste to your food. More importantly, heavy carbon buildup on the heating element can cause the machine to overheat and trigger the burn error code. Always ensure the heating element is completely clean before your next cook.

How do I clean the heating element if soot got inside the base?

Never pour water or liquid cleaners directly into the base of the machine. Instead, dip a cotton swab or a tightly wrung-out damp cloth into a little white vinegar. Gently wipe the silver heating disk to dissolve the burned bits. Let it dry completely for 24 hours before plugging the unit back in.
