my tramontina pressure cooker's sealing ring smells weird after making chili, can i just throw it in the dishwasher?

Diagnosis

The odor is caused by chili's oils and spices, like cumin and chili powder, permeating the silicone sealing ring. This is a normal occurrence in all pressure cookers, as the ring is designed to absorb minor flexing during pressurization, which also allows it to trap food particles and volatile oils.

How to Fix It

Hand-washing is the recommended and most effective method. Do not put the sealing ring in the dishwasher, as the intense heat and harsh detergents can degrade the silicone over time, causing it to crack or lose its elasticity and sealing ability.

1. Remove the ring from the lid.
2. Wash it thoroughly in hot, soapy water, using a mild dish detergent.
3. For persistent smells, create a paste of baking soda and water, rub it into the ring, let it sit for 30 minutes, then rinse.
4. Alternatively, soak the ring for 15 minutes in a 50/50 solution of white vinegar and water, then wash with soap.
5. Always let the ring air dry completely before reinstalling it in the lid.

If That Didn't Work

If the smell persists after cleaning, you can try "steaming it out." Place the clean, dry ring back in the lid. Add 1-2 cups of water to the pot, lock the lid without the pressure regulator (or on the venting setting), and bring it to a simmer for 10-15 minutes. The steam will help release trapped odors. As a last resort, the ring is a consumable part and should be replaced every 12-18 months with a genuine Tramontina replacement ring for optimal safety and performance.

Heads Up

Never store the pressure cooker with the lid locked on the pot, especially with a damp sealing ring inside. This creates a sealed, moist environment perfect for mold and mildew growth, which will cause worse odors and can damage the ring. Store the lid separately or upside-down on the pot.
