Clean the inner pot and lid after every use

The inner pot and lid are the parts that touch food, so they need attention after each meal. Remove the inner pot from the heating base and let it cool for a few minutes. Wash it by hand with warm soapy water and a soft sponge — the pot is stainless steel and won't be damaged by normal scrubbing, but avoid steel wool or abrasive pads that can scratch the surface.

The lid comes apart into three pieces: the main lid, the anti-block shield (a small metal or silicone piece underneath), and the sealing ring. Remove each piece and wash them separately with warm soapy water. The sealing ring absorbs odors and stains easily, so soak it for 15 minutes in hot water with a bit of baking soda if it looks discolored or smells like your last meal.

Dry everything with a clean cloth before reassembling. Do not put the inner pot in the dishwasher unless your model's manual says it is safe — most manufacturers recommend hand washing to preserve the pot's finish.

Key Takeaways

  • Wash the inner pot, lid, anti-block shield, and sealing ring by hand with warm soapy water after every use.
  • Soak the sealing ring in baking soda and hot water for 15 minutes if it holds stains or odors.
  • Wipe down the heating base and exterior with a damp cloth, never submerging them in water.
  • Run the steam release valve under hot water to clear any food particles that block steam flow.
  • Deep clean the inner pot with vinegar and water once a month to remove mineral buildup from cooking liquid.

Clean the heating base and exterior without water

The heating base and the exterior of the lid contain electrical components, so they cannot go in water. Wipe the outside of the base with a damp cloth to remove splatters and dust. Pay attention to the rim where the inner pot sits — food particles and condensation collect there and can affect the seal on your next use.

For stubborn spots on the stainless steel exterior, use a cloth dampened with a small amount of white vinegar. Wipe in the direction of the grain if your model has a brushed finish. Dry when ready with a clean cloth to prevent water spots.

Clear the steam release valve regularly

The steam release valve is a small opening on top of the lid where steam escapes during cooking. Food particles and mineral deposits can lodge inside and prevent the valve from opening fully, which affects cooking performance and safety. After washing the lid, hold it under running hot water and use your finger or a small brush to gently clear the opening from both sides.

If the valve feels stuck or clogged, soak the entire lid in hot water for 10 minutes, then try again. Never force it or use sharp objects that could damage the valve mechanism.

Remove mineral buildup with a vinegar rinse

If you cook with tap water regularly, minerals accumulate on the inner pot and heating element. Once a month, fill the inner pot halfway with equal parts white vinegar and water. Place the pot in the base, close the lid, and run the pressure cooking function on high for two minutes. Let the pressure release naturally for 10 minutes, then manually release any remaining pressure.

Pour out the vinegar mixture and rinse the pot thoroughly with clean water. This process dissolves mineral deposits and keeps the heating element working efficiently. If your tap water is very hard, do this every two weeks instead.

Clean the sealing ring if it retains odors

The silicone sealing ring absorbs flavors from strong foods like fish, curry, or garlic. If your pot smells like last week's dinner, the ring is the culprit. Soak it in a bowl of hot water mixed with two tablespoons of baking soda for 15 to 30 minutes. Scrub gently with a soft cloth and rinse well.

For stubborn odors, place the ring in a bowl of white vinegar and let it sit overnight. Rinse thoroughly before reassembling the lid. Some owners keep two sealing rings — one for savory dishes and one for sweet or mild foods — to prevent flavor transfer.

Inspect the pot for damage before each use

Before you cook, check the inner pot for dents, scratches, or discoloration that might indicate corrosion. Small scratches are normal and safe, but deep dents can affect how evenly heat distributes. Look at the sealing ring for cracks, tears, or permanent deformation — a damaged ring won't seal properly and the pot won't build pressure.

Check the heating base for any signs of water damage or corrosion around the electrical contacts. If you notice rust spots, pitting, or a ring won't seal, contact the manufacturer about replacement parts. Most sealing rings and inner pots are sold separately and cost between $15 and $40.

Store the pot with the lid off to prevent odors

After the pot is clean and dry, store it with the lid off and placed upside down on top of the base. This allows air to circulate inside and prevents the sealing ring from absorbing stale odors while the pot sits unused. If you must store it with the lid on, leave the sealing ring out and store it separately in a sealed container with a piece of baking soda.

Keep the pot in a cool, dry place away from direct sunlight. Avoid stacking heavy items on top of the lid, as this can warp the seal.

Frequently Asked Questions

Can I put the inner pot in the dishwasher?

Most when ready Pot manuals recommend hand washing the inner pot to protect the stainless steel finish. Check your specific model's instructions — some newer pots have dishwasher-safe inner pots, but the lid, sealing ring, and anti-block shield should always be washed by hand.

Why does my pot smell like old food even after washing?

The sealing ring absorbs odors and flavors from cooking. Soak it in hot water with baking soda for 15 to 30 minutes, or in white vinegar overnight. If the smell persists, the ring may need to be replaced — they typically cost $10 to $20.

What should I do if the sealing ring is cracked?

A cracked or torn sealing ring will not seal properly and the pot won't build pressure. You must replace it before using the pot again. Replacement rings are sold by when ready Pot and third-party manufacturers and fit most standard models.

How often should I deep clean the heating element?

Run the vinegar and water cycle once a month if you use tap water regularly. If your water is very hard or you cook daily, do it every two weeks. If you use filtered or distilled water, once every two to three months is usually enough.

Is it safe to submerge the heating base in water?

No. The heating base contains electrical components and should never be submerged. Wipe it with a damp cloth only, and dry it when ready. If water gets inside, unplug the pot and let it dry completely before using it again.
