The Instant Pot® sealing ring is made from food grade silicone. Silicone may pick up food odors during cooking. To remove the odor, try the following:

– Steam Clean: add 2 cups of water or white vinegar and cut-up lemon rind, run the Steam program for 2 minutes with the sealing ring in position. Then, allow the sealing ring to air dry. – Place the sealing ring in the dishwasher. High temperature and strong detergent will usually remove the majority of smells. – Soak the sealing ring overnight in white vinegar, lemon juice, tomato juice, or bleach. Then, run it through the dishwasher. – Store the sealing ring in a plastic bag with ground coffee or baking soda.

Or, you may wish to have one sealing ring for savory and another for sweet foods.
