The lid is the culprit of most of the icky Instant Pot smells. In particular, the silicone ring though an excellent material for sealing the appliance, is prone to absorbing strong odors.
To clean the Instant Pot lid, begin by taking off the removable parts, including the:
- Silicone sealing ring
- Steam release valve
- Anti-block shield
With all of the pieces separated, clean each component with dish soap and water. Set aside to dry.
If the silicone sealing ring is particularly odorous, soak it in white vinegar anywhere from a few minutes to overnight to eliminate the smell. You can also run it in the dishwasher cycle after use to help prevent odor from building up.
(And if you need to, you can always replace the silicone sealing ring. They aren't expensive.)
After cleaning the Instant Pot base and lid, if you are still noticing an odor, run a steam cycle to rid the kitchen tool of any lingering smells.
Fill the Instant Pot insert with two cups of white vinegar. (You can also use two cups of water and a chopped lemon.) Seal the lid and run the appliance on the “steam” setting for two minutes. Remove the ring from the lid and let it air dry completely.
