This post shows how to clean an Instant Pot with vinegar. See how to deep clean an Instant Pot ring, lid, base, and exterior; even what you can put in the dishwasher.
Once you remove both the steam valve and the rubber sealing ring from the lid, you can pop the condensation collector off and put it in the top rack of your dishwasher as well. Most people don't know what this thing is. The condensation collector is just what it sounds like – a small cup on the back of your Instant Pot that collects any extra moisture during cooking.
This might seem straight-forward – but turn the whole heating element (main) part over and dump any burnt food particles in the trash. This goes a long way to making sure you're only cleaning the stuck-on food.
