How to Clean Instant Pot Sealing Ring

Why the Instant Pot Sealing Ring Is the Trickiest Part to Clean

The silicone sealing ring is the large rubber gasket that fits inside the Instant Pot lid and creates the airtight seal needed for pressure cooking. It's also the component that absorbs food odors most aggressively — silicone is porous at a microscopic level and traps volatile odor compounds from everything you cook. Curry, garlic, fish, and other strong-smelling foods can make the ring smell intensely even after washing. Keeping the ring clean and managing odors is one of the most common Instant Pot challenges.

What You'll Need

Dish soap and warm water
White vinegar
Baking soda
Replacement sealing rings (for dedicated sweet/savory use)

White vinegar is the most effective natural deodorizer for silicone sealing rings — it neutralizes odor compounds without damaging the silicone. Baking soda provides additional odor absorption. The most practical long-term solution is having two Instant Pot sealing rings — one dedicated to savory dishes and one for sweet dishes — so odors never cross-contaminate.

Step-by-Step: How to Clean the Instant Pot Sealing Ring

Step 1: Remove the Sealing Ring After Every Use

After the Instant Pot has depressurized and cooled, remove the lid and take out the sealing ring. It sits in a groove around the inside of the lid — pull it out by hand, working around the circumference. Removing it after every use allows it to dry properly and prevents mold growth in the groove.

Step 2: Wash with Dish Soap

Wash the sealing ring in warm soapy water, scrubbing all surfaces with a soft sponge. Pay attention to the inner and outer edges and the groove-contact surface. Rinse thoroughly.

Step 3: Dishwasher Option

The Instant Pot sealing ring is dishwasher-safe — place on the top rack. The dishwasher's hot water and detergent clean the ring effectively and help reduce odors. This is the easiest routine cleaning method.

Step 4: Vinegar Soak for Odor Removal

For rings that smell strongly after washing, soak in undiluted white vinegar for 30 minutes to 1 hour. The acetic acid neutralizes the odor compounds absorbed into the silicone. After soaking, rinse thoroughly and allow to air dry completely.

Step 5: Baking Soda Paste for Stubborn Odors

For very persistent odors, apply a paste of baking soda and water to the ring. Let sit for 15–20 minutes, then scrub with a soft brush and rinse. Follow with a vinegar soak for maximum odor elimination.

Step 6: Steam Clean in the Instant Pot

One of the most effective methods for deodorizing the sealing ring is using the Instant Pot itself:

Place the sealing ring back in the lid.
Add 2 cups of water and 1 cup of white vinegar to the inner pot.
Add lemon peels or a few drops of lemon juice for extra freshness.
Run a steam cycle for 2 minutes.
Allow to cool, remove the ring, and air dry.

The vinegar steam penetrates the silicone and neutralizes absorbed odor compounds from the inside out.

Step 7: Sunlight Treatment

After washing, place the sealing ring in direct sunlight for 1–2 hours. UV light is a natural deodorizer and disinfectant that's particularly effective on silicone. This is one of the best methods for eliminating stubborn food odors from the ring.

Step 8: Clean the Lid Groove

While the ring is removed, clean the groove in the lid where the ring sits. Use a toothbrush to scrub the groove — food residue and moisture accumulate here and can cause mold. Wipe clean with a damp cloth and dry thoroughly before replacing the ring.

The Two-Ring System: Best Long-Term Solution

The most practical solution to sealing ring odor transfer is maintaining two rings:

Ring 1 (savory): Used for curries, stews, soups, garlic dishes, and anything with strong savory odors.
Ring 2 (sweet): Used for desserts, yogurt, rice pudding, and anything where you don't want savory odors.

Label each ring with a permanent marker or use different colored rings. Replace rings every 12–18 months or sooner if they show cracks, deformation, or persistent odors that cleaning can't eliminate.

When to Replace the Sealing Ring

Visible cracks or tears in the silicone
The ring has stretched and no longer fits snugly in the groove
Persistent odors that no cleaning method eliminates
The Instant Pot fails to come to pressure (may indicate a compromised seal)
After 12–18 months of regular use as preventive replacement

Final Thoughts

The Instant Pot sealing ring requires more attention than most appliance components because of silicone's odor-absorbing nature. A combination of dish soap washing, vinegar soaking, and sunlight treatment handles most odor issues. The two-ring system is the most practical long-term solution for households that cook a wide variety of dishes.
