Easy Cleaning for Instant Pot Accessories and Attachments

Overview

Cleaning your instant pot accessories and attachments is just as crucial as washing the main inner pot. I've spent years testing various multi-cookers, and I can tell you that neglected add-ons ruin perfectly good meals. This guide covers the exact methods I use to tackle stubborn odors in silicone sealing rings, baked-on grease on steam racks, and cloudy glass lids. You'll learn how to maintain everything from the anti-block shield to extra ceramic-coated insert pots. Stick around, because I'm sharing my personal 15-minute weekly routine that keeps my kitchen gear spotless and odor-free.

Key Information

Let's talk about the specific gear you're likely hoarding in your lower cabinets. The standard Instant Pot Duo comes with a stainless steel steam rack, a silicone sealing ring, and a plastic condensation collector. If you bought the accessory bundle, you probably also have the tempered glass lid, extra silicone rings, and the silicone egg bite molds. Each material demands a totally different cleaning approach.

Silicone is notoriously porous. I've cooked chili in my 6-quart Instant Pot, then tried to make yogurt the next day using the same ring. That resulted in a gross, cumin-flavored breakfast. That's why I always keep two genuine Instant Pot sealing rings: one red for savory dishes, and one blue for sweet or neutral foods. You can find these official replacements on Amazon for about $12-15 for a two-pack.

Then there's the stainless steel steam rack with handles. It looks indestructible. But if you leave it soaking in hard water, those welded handle joints will develop ugly white calcium deposits. I've tested the OXO Good Grips stainless steel steamer basket as an alternative, and while it folds nicely, the crevices trap tiny rice grains that take forever to scrub out. Stick to the flat rack for easy wiping.

Don't forget the anti-block shield. This little aluminum disc sits under the lid and stops food particles from clogging the steam release valve. Most people forget it even exists. I didn't clean mine for six months until I noticed a weird whistling sound during pressure release. A quick soak in warm soapy water fixed it, but it taught me a valuable lesson about regular maintenance.

Finally, let's address the extra inner pots. The standard stainless steel insert is dishwasher safe. But if you invested in the official ceramic-coated inner pot (usually around $30-40), you need to treat it like a delicate non-stick pan. Abrasive sponges will scratch that coating right off. I use a simple blue Scotch-Brite non-scratch sponge for the ceramic pot, and reserve my heavy-duty stainless steel scrubbers for the bare metal insert.

What about the condensation collector? That tiny plastic cup on the back catches starchy liquid. If you cook a lot of pasta or beans, it fills up fast. I empty mine after every single use. Leaving it attached for a week breeds a slimy, pinkish bacteria that smells like wet dog. A quick rinse under the tap takes ten seconds. Just snap it back on while it's still slightly damp, and it'll seat perfectly.

Let's not forget the silicone egg bite molds and the 7-inch springform pan that come in the official accessory bundle. The egg bite molds are fantastic for meal prep, but they trap greasy residue in the tiny bottom corners. I use a bottle brush with stiff bristles to get into those crevices. The springform pan, on the other hand, is notorious for leaking cheesecake batter into your main insert. I always wrap the outside of my springform pan in a double layer of heavy-duty Reynolds Wrap aluminum foil before pressure cooking. It saves me from scrubbing baked-on sugar off the bottom of the pan later.

Practical Steps or Recommendations

Here is my exact, battle-tested routine for keeping every single attachment pristine. I do this every Sunday afternoon while meal prepping for the week.

1. De-Stinking the Silicone Sealing Rings

Silicone holds onto odors aggressively. If your ring smells like last week's pot roast, don't just throw it in the dishwasher. That rarely works. Instead, I use a baking soda paste. Mix three tablespoons of Arm & Hammer baking soda with one tablespoon of water. Rub this thick paste all over the ring. Let it sit for exactly 20 minutes. Rinse it off with hot water, and the smell will be completely gone. For really stubborn garlic odors, I bake the rings in my oven at 250°F for 30 minutes. The heat opens the silicone pores and bakes the volatile compounds right out.

2. Descaling the Steam Rack and Trivet

Hard water ruins stainless steel finishes. When my steam rack gets cloudy, I fill my kitchen sink with two cups of white Heinz vinegar and warm water. I submerge the rack for 15 minutes. The acetic acid dissolves the mineral buildup instantly. After soaking, I take a stiff-bristled dish brush and scrub the welded joints. Rinse it thoroughly and dry it immediately with a microfiber cloth to prevent new water spots from forming.

3. Deep Cleaning the Anti-Block Shield

Pop the aluminum shield off the underside of the lid. It just pulls straight down. Drop it into a bowl of hot water mixed with a few drops of Dawn Ultra dish soap. Let it soak for 10 minutes. I use an old, soft-bristled toothbrush to gently clean the tiny perforations. Never use steel wool on this part. Aluminum scratches easily, and deep grooves will just trap more grease next time you cook.

4. Washing the Tempered Glass Lid

The glass lid is fantastic for slow cooking. But starchy splatters bake onto the glass if you aren't careful, creating a cloudy mess. I spray the inside generously with Method Heavy Duty Degreaser to break down those stubborn spots. Let it sit for five minutes. Wipe it clean with a damp paper towel. The silicone rim around the glass edge can trap grime, so I run a damp Q-tip around that inner groove to pull out any hidden residue.

5. Maintaining the Ceramic-Coated Inner Pot

This isn't the cheapest option, but the ceramic pot is amazing for making risotto without sticking. To clean it, I only use warm water, a drop of Palmolive, and a soft cellulose sponge. If rice gets burned onto the bottom, I fill it with an inch of water and a squirt of soap. I put it back in the Instant Pot and run the 'Sauté' function for 5 minutes. The simmering water lifts the burnt bits right off without any scrubbing required.

6. Sanitizing the Condensation Collector

That little plastic cup on the back of the unit catches a surprising amount of gross, starchy liquid. I pop it off after every single use. I wash it in the top rack of my dishwasher, but if I'm hand washing, I use a drop of bleach-free sanitizing spray. If you let starchy bean water sit in that cup for a week, it will ferment and smell absolutely vile. Keep a dedicated small brush near your sink just for this tiny part.

Common Mistakes

I'll be honest, I ruined my first silicone sealing ring by making a very stupid error. I left it soaking in a bowl of bleach water overnight. The bleach degraded the silicone, making it brittle and prone to tearing under pressure. Never use harsh chemicals like bleach or ammonia on your instant pot accessories and attachments. Stick to food-safe cleaners like vinegar, baking soda, and mild dish detergents.

Another massive mistake is ignoring the float valve silicone cap. This tiny blue or red rubber piece sits on the underside of the lid, right on the metal float pin. It catches a lot of starchy foam when you cook beans or oats. If you don't pull it off and wash it weekly, it will fuse to the metal pin. I had to use a pair of tweezers to scrape a melted, crusty mess off mine once. Just pinch it, pull it off, and rinse it under the tap.

People also toss the entire main lid into the dishwasher without removing the sealing ring first. The high heat and harsh dishwasher detergents can warp the ring if it's trapped in the tight groove during a heavy wash cycle. Always pry the ring out before washing the lid. It takes two seconds. Use a butter knife or your thumb to lift the edge, and pull it free.

Finally, storing the lid upside down on the pot is a terrible idea if the ring is still damp. Trapping moisture inside the sealed pot creates a breeding ground for black mold. I always store my lid upside down, but I leave the sealing ring off, resting it loosely on top of the glass or metal lid so air can circulate. If you have kids who track mud everywhere and you keep your Instant Pot in a low cabinet, this airflow prevents that musty basement smell from developing inside your cooker.

FAQ

How often should I replace the silicone sealing ring?

I recommend replacing your instant pot accessories and attachments like the sealing ring every 12 to 18 months. Even with perfect cleaning, the silicone eventually stretches out and loses its airtight seal. If you notice steam leaking from the sides of the lid during the preheating phase, it's definitely time to buy a new one.

Can I put the extra ceramic-coated pot in the dishwasher?

You really shouldn't put the ceramic-coated inner pot in the dishwasher. The abrasive detergents and high heat will dull the non-stick finish and cause it to chip over time. Hand washing with a soft sponge takes less than three minutes and will keep that expensive pot looking brand new for years.

Why is my stainless steel inner pot showing rainbow stains?

Those rainbow stains are just harmless mineral deposits from hard water or starchy foods reacting with the steel. I easily remove them by wiping the inside of the pot with a paper towel soaked in white vinegar. The acid breaks down the oxidation instantly, leaving the steel perfectly shiny again.

Is it safe to use steel wool on the steam rack?

I strongly advise against using steel wool on the stainless steel steam rack. While it won't ruin the structural integrity, it will leave behind tiny micro-scratches that trap food particles and cause rust spots. A stiff nylon brush combined with a vinegar soak is much safer and highly effective.
