Key takeaways
- Using scented dish soap: Fragrance can become another odor absorbed by silicone. Choose a mild, unscented formula.
- Scrubbing with abrasive tools: Scratches and cuts create weak spots that can leak steam.
- Boiling the ring on the stove: Direct heat can deform silicone. Use a controlled cooker steam cycle instead.
- Stretching the ring during removal: Pulling hard can change its shape and prevent a reliable seal.
- Putting the ring away wet: Trapped moisture and food particles can worsen the odor.
- Mixing cleaners: Never combine vinegar with bleach, ammonia, or commercial cleaning chemicals.
- Using the wrong size: A 6-quart ring will not properly replace an 8-quart ring, even if it looks similar.
- Ignoring leaks: Steam escaping around the lid is a safety and performance issue, not merely an odor problem.
A lingering odor in an Instant Pot pressure cooker sealing ring usually comes from silicone absorbing aromatic oils from foods such as curry, chili, garlic, onions, fish, and spices. The smell is annoying, but the bigger problem is cleaning the ring incorrectly. Harsh chemicals, boiling the ring for too long, or stretching it during removal can damage the silicone, cause an incomplete seal, or leave cleaner residue where it can contact food. In serious cases, a damaged ring may allow steam to escape and prevent the cooker from reaching pressure.
The safest approach is to remove the ring, wash it with mild dish soap, deodorize it with an acidic or alkaline soak, and dry it completely before reinstalling it. This guide explains how to clean an Instant Pot pressure cooker sealing ring smell in 2026, plus when cleaning is no longer enough.

Replacement rings must match your Instant Pot’s size and model. A 6-quart replacement, such as the Silicone Sealing Ring 6qt for Instant Pot listed at $7.99 for a two-pack, is not interchangeable with an 8-quart ring. An 8-quart option, such as the two-pack Premium Silicone Gasket Replacement Seal listed at $6.99, is designed for larger 8-quart cookers. Before buying, check the quart size, model compatibility, and whether the ring is intended for pressure cooking.
Step-by-Step
1. Unplug, cool, and inspect the cooker (5 minutes)
Unplug the Instant Pot and wait until the inner pot and lid are completely cool. Never remove or wash the sealing ring while the cooker is pressurized or hot. Confirm that the float valve has dropped and that no steam remains trapped inside.
Remove the inner cooking pot and inspect the lid, steam-release components, and sealing-ring track. Food debris or grease in the lid can transfer odor back to a freshly cleaned ring. Do not immerse the electric cooker base in water.
2. Remove the sealing ring gently (2 minutes)
Open the lid and locate the silicone ring seated inside the metal sealing-ring rack. Pull it out slowly from one section at a time. Avoid using a knife, fork, screwdriver, or other sharp tool, which can nick the silicone.
As you remove it, look for cracks, cuts, flattened sections, stretching, discoloration, or areas that no longer sit evenly. A ring that feels loose in the track or has become permanently misshapen should be replaced rather than aggressively scrubbed.
3. Wash the ring with mild soap (5 to 10 minutes)
Rinse the ring under warm running water. Add a small amount of mild, unscented dish soap to a soft sponge or nylon brush and clean the entire ring, including the inner and outer edges. Pay special attention to greasy areas, since trapped cooking oil is a common source of persistent odor.
Do not use bleach, ammonia, oven cleaner, abrasive powders, steel wool, or strongly fragranced cleaners. These products can damage silicone or leave residues. Rinse until the water runs clear and the surface no longer feels slippery.
4. Deodorize with a vinegar steam cycle (15 to 20 minutes)
For moderate odors, place the cleaned sealing ring back into the lid temporarily, then add 2 cups of water and 1 cup of white vinegar to the inner pot. Secure the lid and run a short pressure-cooking cycle for 5 minutes. Allow a natural release for at least 10 minutes, then carefully release any remaining pressure according to your cooker’s instructions.
The warm vinegar steam can freshen the lid, steam-release pathway, and sealing ring at the same time. Once the cycle is complete, unplug the cooker, let everything cool, and remove the ring again. Rinse it thoroughly with clean water. Never operate the cooker without the inner pot, and never exceed the cooker’s maximum fill line.
5. Use a baking soda soak for stubborn smells (30 minutes to overnight)
If the odor remains, dissolve 2 tablespoons of baking soda in 4 cups of warm water. Submerge the ring in the solution for at least 30 minutes. For a particularly strong smell, leave it for several hours or overnight in a clean container.
Rinse the ring thoroughly afterward. Do not combine baking soda and vinegar in the same container expecting a stronger cleaner; they largely neutralize each other. Use them as separate treatments, rinsing between steps.
6. Air-dry completely (several hours)
Pat the ring with a clean towel, then place it on a drying rack or clean towel in a well-ventilated area. Let it air-dry completely, ideally for several hours. Do not store it damp inside the lid, where moisture and food residue can encourage mildew-like odors.
Silicone can retain smells temporarily, so a faint scent immediately after washing does not always mean the cleaning failed. Sunlight and fresh air may help, but avoid prolonged exposure to intense heat, which can accelerate silicone aging.
7. Reinstall and test the seal (5 minutes)
Press the dry ring evenly into the sealing-ring rack. Run a finger around the entire circumference to confirm that it is seated flat, without twists or gaps. Check that the ring is not folded under itself.
Add at least 2 cups of water to the inner pot and run a brief pressure cycle. Watch for unusual steam escaping around the lid. If the cooker cannot seal, the ring may be incorrectly installed, incompatible, damaged, or too stretched to work properly. Do not continue pressure cooking until the issue is corrected.

How Often
Wash the sealing ring after every use, especially after cooking oily, spicy, sweet, or strongly flavored foods. Run a vinegar steam cycle about once a month if you use the cooker frequently, or whenever the lid develops a noticeable odor. Keep separate rings for savory foods and desserts if you often make yogurt, cheesecake, oatmeal, or other foods that easily absorb savory smells.
After washing, store the lid upside down or leave it loosely placed on the cooker so air can circulate. If you own an extra ring, store it clean and dry in a ventilated location rather than sealed in a damp plastic bag.
When to Call a Pro or Replace
Most sealing-ring problems do not require a repair technician. Replace the ring if it has visible cracks, cuts, tears, permanent flattening, hard or brittle areas, unusual swelling, or an odor that remains after multiple thorough cleanings. Replacement is also sensible if the cooker repeatedly fails to seal with the ring installed correctly.
Stop using the cooker and contact the manufacturer or a qualified appliance service professional if the lid, sealing-ring rack, float valve, steam-release handle, or electrical base is damaged. Do not attempt to repair a pressure-lid mechanism with household glue or unapproved parts. Replacement rings are relatively inexpensive—commonly about $7 to $15 for a two-pack, depending on size and brand—so replacing a questionable gasket is safer than forcing it to work.
FAQ
Can I put an Instant Pot sealing ring in the dishwasher?
Many Instant Pot silicone rings are dishwasher-safe, but confirm this in your model’s manual. Place the ring on the top rack if permitted, and avoid washing it with heavily scented detergent. Hand washing is gentler and makes it easier to inspect the ring for damage.
Why does my sealing ring still smell after cleaning?
Silicone naturally absorbs oils and aromatic compounds. Strong foods may leave an odor even after the surface is clean. Repeat the baking soda soak, let the ring air out for several hours, or use a separate ring for savory recipes. Replace it if the smell is persistent and unpleasant after repeated cleaning.
Can I cook with a smelly sealing ring?
A smell alone does not necessarily mean the ring is unsafe, provided it is intact, clean, and made for your cooker. However, a ring that is cracked, stretched, sticky, brittle, or unable to seal should not be used. When in doubt, install a compatible replacement.
How do I prevent odors in a new sealing ring?
Wash the ring before its first use, dry it fully, and rinse the lid after cooking strongly flavored foods. Leaving the lid slightly ajar between uses improves ventilation. Keeping separate rings for savory and sweet foods is the most reliable way to prevent flavor transfer.
