How to clean an Instant Pot: after each use, wash the stainless inner pot in hot soapy water (or the dishwasher), hand-wash the lid and remove its parts — sealing ring, steam release valve, anti-block shield, and float valve — for individual cleaning. Wipe the cooker base with a damp cloth, deodorize the sealing ring with baking soda or vinegar steam, and dry everything before reassembling. The routine takes 10 minutes; the monthly deep clean takes 30.
This guide is research-based, compiled from manufacturer care instructions (Instant Pot/Instant Brands, Ninja Foodi, Breville Fast Slow Pro) and widely published pressure-cooker maintenance guidance. Below: why the sealing ring smells and how to fix it permanently, the complete part-by-part cleaning procedure, lid-component care most owners skip, what never to do, troubleshooting sealing failures, and an FAQ.
Anatomy of an Instant Pot: What Actually Needs Cleaning
An electric pressure cooker has more separate food-contact parts than it appears: the stainless inner pot (the cooking vessel), the lid with its silicone sealing ring (the gasket that makes pressure possible), the steam release valve (the wobbly knob on top), the anti-block shield (the small metal cap under the lid covering the steam pipe), the float valve (the little pin that pops up under pressure), the condensation collector (the small plastic cup on the back), and the cooker base with its heating element. Food residue in any of these causes specific problems — and the sealing ring is the source of 90% of Instant Pot odor complaints.
The sealing ring deserves special attention because silicone absorbs odors. Cook curry, chili, or bone broth, and the ring holds that smell for weeks, transferring a ghost of it to the next thing you cook — yogurt makers know this pain intimately. The ring is also a wear item: stretched, cracked, or deformed rings cause the steam leaks and “won’t come to pressure” failures that frustrate owners. Cleaning it properly and replacing it on schedule solves most Instant Pot problems before they start.
What You’ll Need
- Dish soap and a soft sponge
- An old toothbrush for lid parts and valves
- Baking soda and white vinegar for deodorizing
- A spare silicone sealing ring instant pot sealing ring Check Price on Amazon → (one for savory, one for sweet — the pro move)
- Microfiber cloths for the base
How to Clean an Instant Pot: Step-by-Step
Step 1: Cool, unplug, and disassemble the lid
Let the cooker cool and unplug it. Remove the lid and take out its components: pull the sealing ring out of its wire rack (it lifts out easily — note how it seats for reassembly), pull off the steam release valve (it lifts straight up with a tug), pop off the anti-block shield (push it up from underneath — it’s snug by design), and push the float valve out from the top so it drops out below with its tiny silicone cap. Lay the small parts on a towel — the float valve’s silicone cap is easy to lose.
Step 2: Wash the inner pot
The stainless-steel inner pot is the easy part: hot soapy water and a soft sponge, or the dishwasher. For stuck-on food, soak with hot water and a squirt of dish soap for 20 minutes — stainless releases everything with soaking. For the rainbow heat-tint discoloration stainless develops, a paste of baking soda or a wipe with white vinegar restores the finish.

Dry the pot fully, including its exterior bottom — water on the pot’s outside can damage the base’s sensors over time.
Step 3: Wash the lid and its small parts
Hand-wash the lid in hot soapy water — never put the lid in the dishwasher (Instant Brands advises hand-washing; the harsh environment degrades the sealing components and can warp the lid). Scrub the sealing ring’s groove in the lid with the toothbrush, wash each small part (steam valve, anti-block shield, float valve and its cap) individually, and poke through the steam pipe opening with the toothbrush to clear any food particles. Rinse everything and air-dry. Inspect the anti-block shield and steam pipe for blockages — a clogged steam path is a safety issue, not just a cleaning one.
Step 4: Deodorize the sealing ring
If the ring smells of past meals: Method 1 (bake it out): place the clean, dry ring on a baking sheet and bake at 250°F (120°C) for 30–45 minutes — heat drives the absorbed odor compounds out of the silicone. This is the most effective method and widely recommended by the Instant Pot community. Method 2 (vinegar steam): put 2 cups of water and 1 cup of vinegar in the inner pot, add the ring (draped over the trivet or just placed in), and pressure-cook 5 minutes with a quick release. Method 3 (sunlight): leave the ring in direct sunlight for a day — UV breaks down odor compounds. Method 4 (baking soda soak): soak overnight in water with 2 tablespoons of baking soda. Use Method 1 for stubborn smells; combine methods for the truly haunted ring.
Step 5: Clean the condensation collector and rim
Slide out the condensation collector cup from the back of the cooker, empty it, and wash with hot soapy water — it collects starchy, greasy drips that sour quickly. Wipe the cooker’s outer rim (the channel where the lid seats) with a damp cloth and the toothbrush — dried food in this channel prevents the lid from seating properly and is a common cause of steam leaking around the lid edge.
Step 6: Wipe the base (carefully)
Wipe the cooker base’s interior — the heating element area — with a barely-damp cloth to remove any food that fell in. Never pour water into the base or submerge it. If food is burned onto the heating element, a baking-soda paste and gentle wiping handles it; never use abrasive pads on the element. Wipe the exterior housing with a damp cloth. Let the base air-dry fully.
Step 7: Inspect, reassemble, and store
Before reassembling, inspect the sealing ring: it should be pliable with no cracks, tears, or permanent deformation — press it; if it stays dented instead of springing back, replace it. Seat it evenly in the lid’s rack (an unevenly seated ring is the number one cause of pressure failures). Reinstall the float valve with its silicone cap, the anti-block shield, and the steam release valve. Store the cooker with the lid upside-down on top of the base — this airs out the ring and prevents odor buildup between uses. Never store it sealed.
The Two-Ring System (and When to Replace the Ring)
Serious Instant Pot users keep two sealing rings: one for savory foods (curry, chili, broth) and one for sweet/neutral (yogurt, cheesecake, rice). It eliminates flavor transfer completely and each ring lasts longer. Rings are inexpensive ($8–$12 for genuine two-packs) and model-specific — match your exact model and size (3, 6, or 8 quart).
Replace the ring every 12–18 months with regular use, or sooner if you see cracks, permanent stretching (it no longer fits snugly in the rack), or persistent steam leaking around the lid that cleaning doesn’t fix. A worn ring is the cause of most “my Instant Pot won’t come to pressure” complaints — a $10 part, not a broken cooker. Keep a spare on hand; they always fail when you’re mid-recipe.
Sauté-Mode Cleanup: Deglazing the Smart Way
The inner pot’s sauté function browns meat and aromatics before pressure cooking — and leaves fond (browned bits) welded to the bottom. Don’t scrub it: pour in a cup of water or broth while the pot is still hot and scrape with a wooden spoon — the fond dissolves into a flavorful base for the pressure-cook phase. This is deglazing, and it both cleans the pot and improves the dish. Only after deglazing should you wash normally; attacking fond with abrasives is unnecessary work that scratches the stainless.
What Never to Do
1. Never put the lid in the dishwasher. 2. Never immerse the cooker base in water. 3. Never use abrasive pads on the inner pot’s interior — scratches harbor bacteria and impair the finish. 4. Never operate with a damaged or missing sealing ring, float valve cap, or anti-block shield — these are safety components. 5. Never force a lid that won’t open — wait for pressure to release fully; forcing a pressurized lid is extremely dangerous. 6. Never ignore food in the steam pipe or valves — blocked steam paths compromise the pressure regulation the cooker’s safety depends on.
Maintenance Schedule
| Frequency | Task |
|---|---|
| Every use | Wash inner pot; hand-wash lid; wipe rim and base; air-dry |
| Weekly | Remove and wash all lid small parts; clean condensation collector |
| Monthly | Deep-clean: deodorize ring, detail steam pipe and valves, inspect ring for wear |
| 12–18 months | Replace sealing ring (sooner if damaged) |
Troubleshooting: Sealing Failures and Error Codes
Won’t come to pressure / steam leaks around lid: the sealing ring is mis-seated, dirty, or worn — remove, clean, reseat evenly, or replace. Also check food debris in the rim channel. Steam leaks from the float valve area: the valve’s silicone cap is missing or damaged, or food is stuck in the valve — disassemble and clean. Burn notice (OVHT/BURN): usually not a cleaning issue — insufficient thin liquid, or food scorched on the pot bottom; deglaze thoroughly after sautéing and ensure enough liquid. But a pot with baked-on residue from prior use triggers it too — keep the pot’s interior clean. Lid won’t close: the sealing ring isn’t seated in its rack, or the float valve is stuck up — check both. Persistent food smell in everything: the ring needs the bake-out treatment or replacement; consider the two-ring system.
Frequently Asked Questions
How do I get the smell out of my Instant Pot sealing ring?
Bake the clean, dry ring at 250°F (120°C) for 30–45 minutes — heat drives absorbed odors out of the silicone more effectively than any soak. Alternatives: pressure-cook it in vinegar water for 5 minutes, leave it in direct sunlight for a day, or soak overnight in baking-soda water. For permanent odor transfer prevention, use the two-ring system: one ring for savory, one for sweet.
Can I put the Instant Pot lid in the dishwasher?
No — hand-wash only. The manufacturer advises against dishwasher-cleaning the lid because the harsh detergent and heat degrade the sealing components and can warp the lid over time. Disassemble the small parts (ring, valves, shield) and wash everything by hand in hot soapy water — it takes five minutes and preserves the parts that make pressure cooking safe.
How often should I replace the sealing ring?
Every 12–18 months with regular use. Replace sooner if you see cracks, tears, permanent stretching, or if steam leaks around the lid persist after cleaning and reseating. A worn ring is the most common cause of pressure failures — and at $8–$12, it’s the cheapest fix in the appliance. Keep a spare; they fail mid-recipe.
Why won’t my Instant Pot come to pressure?
In order of likelihood: the sealing ring is mis-seated, dirty, or worn; food debris in the lid rim channel; insufficient thin liquid in the pot; the steam release valve isn’t set to Sealing; or the float valve is stuck. Work through that list before assuming a malfunction — genuine pressure-system failures are rare compared to ring and seating issues.
What is the anti-block shield and why does it matter?
It’s the small metal cap under the lid covering the steam pipe opening — it prevents food particles from blocking the steam release path. Pop it off and clean it (and the pipe beneath) regularly; a blocked steam path compromises the pressure regulation the cooker’s safety systems depend on. It’s a safety component, not an accessory — never operate without it.
Can I use my Instant Pot for canning?
Electric pressure cookers including the Instant Pot are not recommended for pressure canning low-acid foods by food-safety authorities — they haven’t been validated to hold the precise pressures and temperatures that safe canning requires, and altitude affects them differently than stovetop canners. They’re fine for water-bath canning high-acid foods (jams, pickles) following tested recipes. Don’t use the pressure-cook function as a canning shortcut.
