Wiping out the inner pot after dinner handles the obvious mess, but the parts that actually cause a lingering smell, a lid that won't seal properly, or a pressure cooker that won't come up to pressure at all are the ones most people never think to check: the silicone sealing ring, the float valve, and the anti-block shield on the underside of the lid.

This applies to any current electric pressure cooker or multi-cooker, including the Instant Pot Duo and Ninja Foodi — the inner pot cleans the same way on both; the main difference is how the lid's vent and float valve are laid out.

What actually needs cleaning (it's not just the inner pot)

The silicone sealing ring sits in a removable rack on the underside of the lid and is what actually traps odor, since silicone absorbs strong food smells far more than the stainless inner pot does. A sealing ring that still smells like last week's curry after a normal wash is completely normal, not a defect.

The float valve (the small pin that rises to indicate pressure) and the anti-block shield (a small perforated cap over the steam release opening, also on the lid's underside) catch food splatter during cooking and can stop the lid from sealing or venting properly if they're never removed and cleaned.

How often to clean it

Wash the inner pot, lid, and sealing ring after every use — none of this takes more than a few minutes and it stops buildup before it hardens or an odor sets in.

Pull the float valve and anti-block shield for a closer look every few uses, and sooner if you just cooked something that foamed or splattered heavily, like beans, oats, or a dish with a lot of starch.

Step-by-step: inner pot, lid, and sealing ring

1. Unplug the cooker and let it cool. 2. Remove the inner pot and wash with warm soapy water, or run it through the dishwasher if your manual rates it safe (most stainless inner pots are). 3. Pop the sealing ring out of its rack on the lid's underside, and hand-wash or dishwasher-wash it separately — it comes out without tools on nearly every current model. 4. Wipe the lid itself, including the rack the ring sits in, with a damp cloth, then dry everything fully before reassembling, since trapped moisture under the ring is what lets odor build back up.

Step-by-step: the float valve and anti-block shield

1. Check your manual for how your specific model's float valve and anti-block shield detach — most twist or pop off by hand. 2. Rinse both under warm water and use a toothpick or small brush to clear any dried food from the float valve's opening and the shield's perforations, since a blocked vent is a common reason a cooker won't pressurize or won't release pressure properly. 3. Dry both fully and snap them back into place before the next use.

Getting rid of a lingering smell

A sour or musty smell after a normal wash is almost always the sealing ring, not the pot — pull it out and wash it on its own rather than re-washing the parts that are already clean.

Many owners keep a second sealing ring and dedicate one to savory dishes and one to anything sweet, like yogurt or desserts, since a ring that's absorbed garlic and onion can carry that flavor into a dessert otherwise. For a stronger clean, soak the ring in a bowl of warm water with a splash of white vinegar for 15-20 minutes, then rinse and air-dry fully.

Frequently Asked Questions

Why does my Instant Pot smell even after I wash it?
The smell is almost always trapped in the silicone sealing ring, not the stainless inner pot. Pop the ring out of the rack on the lid's underside and wash it separately — a quick soak in warm water with a splash of vinegar helps lift a stubborn smell.
Can I put the sealing ring and inner pot in the dishwasher?
On most current models, yes — check your manual to confirm, since it varies slightly by brand. Either way, pull the sealing ring out of its rack first rather than running it through while still attached to the lid.
Why won't my electric pressure cooker come up to pressure?
A blocked float valve or anti-block shield is one of the most common causes, since dried food in either one can stop the lid from sealing or venting correctly. Remove both and clear any buildup with a toothpick or small brush before assuming there's a bigger mechanical problem.
