Quick answer

Clean your Kuhn Rikon pressure cooker seal after every use by hand-washing with mild soap and warm water. For stubborn stains or odors, use a baking soda paste. Always dry the seal completely before storing to prevent mold and maintain elasticity.

Why seal care matters for your pressure cooker

The rubber seal (also called a gasket) is the most critical part of your pressure cooker — it creates the airtight barrier needed for pressure to build. Over time, food residue, grease, and odors can degrade the rubber, leading to leaks or failed pressurization. Regular cleaning prevents these issues and extends the seal's lifespan.

When to clean vs. replace the seal

Clean the seal after every use. Replace it if you notice cracks, brittleness, a permanent stretched shape, or if the seal no longer forms a tight fit even after cleaning. Kuhn Rikon recommends replacing the seal every 1–2 years depending on use frequency.

Step-by-step: How to clean your Kuhn Rikon pressure cooker seal

  1. Remove the seal: Take the rubber seal out of the lid groove. Most Kuhn Rikon models let you pop it out easily with your fingers. Check the groove for trapped food bits. Common mistake: Leaving the seal in the lid while cleaning can miss hidden residue in the groove.
  2. Wash with mild soap and warm water: Hand-wash the seal using a soft sponge or cloth and a few drops of dish soap. Avoid abrasive scrubbers that can damage the rubber surface. Rinse thoroughly. Checkpoint: If the seal still feels greasy after washing, repeat with a drop of degreasing dish soap.
  3. Remove stains or odors with baking soda: Make a paste of 3 parts baking soda and 1 part water. Apply it to the seal and let it sit for 10 minutes. Rinse completely. This works well for lingering food smells. Common mistake: Do not use bleach or chlorine bleach, which can harden the rubber.
  4. Dry completely before storing: Pat the seal with a soft cloth and let it air dry for a few hours. Store it in a cool, dry place away from heat sources. A bent or folded seal over the lid loosely. Checkpoint: A stored seal can cause mold growth and permanent deformation.
