It is not necessary to remove the sealing ring after each use. One should remove and clean the sealing ring following every 5-6 uses, or if any food that splatters was prepared.

The sealing ring is made from food grade silicone and is extremely durable. Under normal conditions it should be fine for 18 – 24 months. If you notice cracks, leaking or deformation in the sealing ring, it should be replaced. However, the sealing ring is porous and may absorb odors and become discolored over time. To avoid discoloration and odors, one may wish to change the sealing ring every 6 – 12 months.
