TL;DR
Silicone absorbs odor molecules into the material itself, so a ring that smells like last week's curry is not dirty on the surface, it is saturated. A hot soapy wash followed by a baking soda soak and a full air dry removes most of it, and a steam cycle with water and vinegar removes more. Rings are consumable parts, so replace one every twelve to eighteen months, and keep a second ring for strongly flavored cooking.
Why silicone holds smells
Silicone is slightly porous and oil loving at the molecular level. Aromatic compounds from garlic, spices, and fats migrate into the material during high pressure cooking, when heat and pressure drive them deeper than they would ever go in an open pot.
That is why scrubbing the surface does not help much. The odor is inside the ring, not on it, and getting it out means giving it time and the right conditions to migrate back out.
The routine after every use
Do this and the problem mostly never starts.
- Let the lid cool, then pull the sealing ring out of its rack by working around the circumference with your fingers. Never pry it with a knife or a screwdriver.
- Wash the ring in hot soapy water, or run it on the top rack of the dishwasher if the manual allows.
- Wash the lid itself, and pay attention to the underside, where splatter dries in the recesses.
- Remove and rinse the anti block shield if your model has one, since food gets trapped underneath it.
- Check the float valve moves freely and wipe around its seat.
- Empty and wash the condensation collector cup on the back of the unit.
- Air dry everything completely, then store the lid upside down or resting loose rather than locked on, so air moves through.
That last habit prevents more odor than any cleaning method.
How do you get the smell out of a sealing ring?
Soak it. Submerge the ring in a bowl of warm water with a few tablespoons of baking soda for a few hours or overnight, then rinse and air dry it fully, ideally outdoors in fresh air or near a sunny window. Sunlight and moving air do a lot of the work.
If odor remains, run a steam cycle. Put the ring back in the lid, add two cups of water and a cup of white vinegar to the inner pot, and run a short steam or pressure cycle. Release the pressure, remove the ring, rinse it, and air dry it again.
Repeat rather than escalate. There is no product that pulls odor out of silicone faster than time and airflow.
What never touches a sealing ring
| Avoid | Why |
|---|---|
| Chlorine bleach | Degrades silicone and leaves its own smell |
| Oven cleaner or strong caustics | Attacks the material |
| Abrasive pads or scouring powder | Micro tears that trap more odor |
| Knives or metal tools for removal | Nicks that break the seal |
| Cooking oil rubbed on to mask smell | Feeds the problem |
| A stretched or cracked ring | It will not hold pressure |
Damage matters more than smell. A nicked, cracked, hardened, or stretched ring is a safety issue, because a pressure cooker that cannot seal properly either fails to come to pressure or vents unpredictably.

When to replace instead of clean
Manufacturers generally recommend replacing the sealing ring every twelve to eighteen months with regular use, sooner with heavy use. Replace immediately if the ring is stretched so it no longer sits snugly in the rack, if it has cracks or nicks, if it has gone hard and lost its flexibility, or if the cooker keeps failing to reach pressure.
Rings are inexpensive relative to the appliance and widely available from the manufacturer or a compatible maker. Buying two and dedicating one to savory cooking and one to sweet or plain cooking is the single best fix for flavor transfer.
Putting the ring back correctly
Seat the ring inside the metal rack on the underside of the lid, working it under the tabs all the way around, then run a finger around the full circumference to confirm it sits flat with no bulges or twists.
Test before you cook. Lock the lid on with a cup of water in the pot, set a short cycle, and confirm it comes to pressure normally. A ring that is seated wrong usually announces itself as steam escaping around the rim.
Gaskets are a recurring theme in kitchens. The same trapped food and moisture problem drives cleaning a refrigerator door gasket and why a dishwasher starts to smell, and the absorption problem is identical to clearing odors from food storage containers. Broader appliance care sits in the small appliance cleaning guide and the wider kitchen cleaning guide.
FAQ
Can a pressure cooker sealing ring go in the dishwasher?
For most models yes, on the top rack, and the manual will confirm it. Dishwasher washing removes surface residue well but does little for odor absorbed into the silicone, so follow it with a baking soda soak and a long air dry if smell is the issue.
How do I get curry smell out of a silicone sealing ring?
Soak the ring overnight in warm water with a few tablespoons of baking soda, rinse, and air dry it fully in open air or sunlight. If the smell persists, run a steam cycle with two cups of water and a cup of white vinegar, then air dry again.
How often should the sealing ring be replaced?
Every twelve to eighteen months with regular use, and immediately if it is stretched, cracked, nicked, or hardened. A ring that no longer sits snugly in its rack cannot hold pressure reliably, which makes replacement a safety matter rather than a preference.
Why does my pressure cooker not come to pressure anymore?
The most common cause is a sealing ring that is seated incorrectly, stretched, or damaged. Check that the ring sits flat under every tab, that the float valve moves freely, and that the anti block shield is clean and correctly installed.
Should I use two sealing rings?
It is a practical habit if you cook a wide range of foods. Dedicate one ring to strongly flavored savory dishes and another to plain or sweet cooking, and label them. This prevents the flavor transfer that no amount of cleaning fully eliminates.
Can I use bleach to deodorize a sealing ring?
No. Chlorine bleach degrades silicone over time and leaves its own residual smell in the material. Warm water with baking soda, a vinegar steam cycle, and thorough air drying are the effective and safe approaches for silicone gaskets.
