7 Instant Pot Cleaning Mistakes to Avoid (Tested 2026)

By Tom Bradley · June 5, 2026

Overview

I've owned my Instant Pot Duo 7-in-1 for over four years. In that time, I've made every error in the book. This guide covers the exact instant pot cleaning mistakes to avoid if you want your pressure cooker to last. We will look at the silicone sealing ring, the anti-block shield, and the heating element. I'll share the specific products I use, like Bar Keepers Friend and Dawn Powerwash. You'll also learn why your chili always tastes like last week's cheesecake. My goal is to save you from buying replacement parts or, worse, a whole new machine.

Key Information

Let's break down the anatomy of your cooker. The Instant Pot isn't just a metal bowl with a lid. It has several distinct components that require entirely different care routines. I learned this the hard way after ruining my first sealing ring.

The Inner Pot

This is the removable stainless steel insert. For the 6-quart models, it measures about 8.6 inches in diameter. It's dishwasher safe. However, I never put mine in the dishwasher. The harsh detergents eventually cause micro-scratches. I hand wash it with a non-scratch sponge and warm soapy water. If you have burnt-on food, a 15-minute soak does the trick.

The Silicone Sealing Ring

This is the culprit behind 90% of odor complaints. Silicone is highly porous. It absorbs the volatile oils from cumin, garlic, and onions. If you cook a spicy curry on Monday, your Tuesday oatmeal will taste like turmeric. I recommend buying two rings. Keep one for savory dishes and one for sweet. They cost about $12-15 for a pack of two on Amazon. Store them in a Ziploc bag with baking soda when not in use.

The Lid and Anti-Block Shield

The lid houses the float valve and the steam release handle. Underneath, there's a small metal disc called the anti-block shield. This prevents food particles from clogging the steam pipe. I pop this off with a butter knife every single time I cook foamy foods like beans or oatmeal. If you skip this, you'll get a sputtering valve and a messy counter.

The float valve is that little metal pin that pops up when the pot pressurizes. It has a tiny silicone cap on the inside. This cap falls off easily. I lost mine down the garbage disposal during my first month of ownership. Always plug the sink. If the cap is missing, the pot won't seal.

The Cooker Base

The base contains the heating element and the microprocessor. It is strictly a wipe-down only zone. Never submerge this in water. I've seen people try to rinse out spilled soup under the tap. This instantly fries the internal sensors. A damp microfiber cloth is all you need here.

I'll be honest, keeping track of all these parts feels like a chore at first. But once you build a routine, it takes less than five minutes after dinner. When your landlord inspects next week, or you're just trying to keep your kitchen spotless, these small habits make a massive difference.

Essential Supplies I Keep Under My Sink

Bar Keepers Friend Soft Cleanser ($6-8): Best for removing rainbow heat tints on the inner pot.
Dawn Powerwash ($5-7): Cuts through greasy residue on the exterior lid without scrubbing.
Weiman Stainless Steel Wipes ($8-10): This isn't the cheapest option, but it prevents streaks on the brushed metal base.
Q-tips or a small detailing brush ($3): Crucial for digging gunk out of the lid locking groove.

Practical Steps or Recommendations

Here is my exact routine for maintaining a spotless pressure cooker. I've tested this on my own appliance weekly.

1. The Steam Clean Method (For the Lid and Base)

This is a game-changer for removing hidden grime. Fill the inner pot with 2 cups of water and a sliced lemon. Add one tablespoon of white vinegar. Lock the lid and set the valve to sealing. Run the Steam function for exactly 2 minutes. Let it naturally release for 10 minutes. The hot, acidic vapor loosens gunk trapped under the anti-block shield and around the float valve. Wipe the inside of the lid with a paper towel. You'll be shocked by the yellow residue that comes off.

2. Deodorizing the Sealing Ring

If your ring smells like old roast, don't throw it away yet. I use a two-step process. First, wash it in the top rack of the dishwasher. The high heat opens the silicone pores. Next, place the damp ring in direct sunlight for 3 to 4 hours. UV rays naturally break down the odor-causing compounds. If it's winter and you lack sun, bake it in the oven at 250°F for 20 minutes. I've tested this oven method on my own silicone baking mats too, and it works perfectly.

3. Descaling the Heating Element

Mineral buildup happens if you live in a hard water area. I noticed a chalky white ring on my heating element after about six months. To fix this, unplug the unit and let it cool completely. Dampen a cloth with equal parts water and distilled white vinegar. Wring it out until it's barely damp. Gently scrub the element. Never use steel wool here. It leaves behind tiny metal shards that can cause a short circuit.

4. Polishing the Exterior

The brushed stainless steel exterior shows every fingerprint. I use Weiman Stainless Steel Cleaner and Polish. Spray a tiny amount onto a microfiber cloth, not directly on the pot. Wipe in the direction of the grain. This takes 30 seconds and keeps the display panel looking brand new.

5. The Post-Dinner Party Deglaze

After hosting a dinner party where I made a massive batch of beef bourguignon, the inner pot had a scorched ring of fond around the bottom. Instead of scrubbing for 20 minutes, I poured in an inch of water and a squirt of Dawn dish soap. I hit the Saute button and let it simmer for 5 minutes. The heat lifted the burnt bits right off. I just wiped it clean with a wooden spoon.

Common Mistakes

Even experienced home cooks mess this up. Here are the specific instant pot cleaning mistakes to avoid at all costs.

Mistake	Why It's Bad	The Fix
Using abrasive scrubbers on the inner pot	Steel wool creates micro-scratches where bacteria hide and food sticks.	Use a blue non-scratch Scotch-Brite sponge or a silicone scrubber.
Leaving the sealing ring installed during storage	Traps moisture, leading to black mold growth in the lid groove.	Remove the ring, wash it, and store the lid upside down.
Submerging the base in the sink	Water enters the ventilation holes and destroys the motherboard.	Wipe the base with a damp cloth and mild dish soap.
Ignoring the condensation collector	Stagnant water breeds bacteria and creates a sour smell.	Pop off the small plastic cup on the back and empty it weekly.

The Dishwasher Trap

Many manuals state the lid is top-rack dishwasher safe. I'll be honest, this takes elbow grease to hand wash, so the dishwasher is tempting. But the high-heat drying cycle warps the plastic components over time. I warped the steam release handle on my first Instant Pot Lux this way. It cost me $18 to replace the entire lid assembly. Now, I only put the inner pot and the sealing ring in the dishwasher.

The Baking Soda Paste Error

People love using baking soda and water to scrub the exterior. The problem? The paste gets pushed into the seams around the digital display. Once it dries, it turns into a hard, white crust that is nearly impossible to remove. I spent 45 minutes with a toothpick trying to dig it out of my control panel crevices. Stick to liquid sprays for the outside.

Forgetting the Rim and Groove

When you lift the lid, look at the metal rim of the cooker base. There is a narrow groove where the lid locks in. Soup and grease splatter here during pressure release. If you have kids who track mud everywhere and you're rushing to get dinner on the table, it's easy to skip wiping the rim. But taking 10 seconds to run a wet paper towel around the edge saves you from a ruined meal. I once ignored a piece of dried rice on the rim. The pot failed to seal, the liquid boiled away, and I triggered the burn warning right before my guests arrived.

FAQ

How often should I replace the silicone sealing ring?

Instant Pot officially recommends replacing the sealing ring every 12 to 18 months. However, I replace mine every 10 months because I cook highly spiced foods weekly. If the ring feels stiff, shows visible cracks, or holds odors even after baking, toss it immediately. A failing ring will cause steam leaks and prevent the pot from pressurizing.

Can I use bleach to clean the inner stainless steel pot?

You should never use bleach or chlorine-based cleaners on stainless steel. The chlorine reacts with the chromium in the steel, causing severe pitting and rust. I stick to Bar Keepers Friend for tough stains, which uses oxalic acid instead. It removes rainbow heat tints in about 30 seconds without damaging the metal.

Why is there water pooling under my Instant Pot after cooking?

This usually means your condensation collector is full or missing. It's a small, removable plastic cup located on the back right side of the base. I check this cup every time I cook rice or soups, as they release a lot of steam. Just pull it out, dump the water in the sink, and snap it back into place.

Is it safe to use a magic eraser on the outside of the cooker base?

Magic Erasers are essentially micro-sandpaper, so they will ruin the brushed finish on the stainless steel exterior. I used one on my Duo Evo Plus and left a dull, cloudy patch that catches the light terribly. Use a dedicated stainless steel polish and a soft microfiber cloth to maintain the factory shine.
