If you allow Instant Pot to cool naturally, the lid is normally clean, with condensation water only. You don’t need to unscrew anything to wash, simply wipe dry with a dry cloth.

If you use quick release (letting steam out from steam release handle) or cook sticky foods, you may need to remove the anti-block shield (not the whole steam release assembly) for cleaning. After cleaning, place the anti-block shield back on. You may also want to pull the steam release handle out and the sealing ring for cleaning. Please always inspect the float valve to make sure it can move up and down easily without obstruction. You can remove the float valve by taking out the small silicone rubber ring for cleaning.
