Question: How to clean a pot after cooking rice?
Option 0: Perfectly cooked rice still leaves a little residue stuck rice on the pot bottom or sides. And  there may be a film left behind as well. Put a little baking soda and a drop or two of dish soap and hot water, and brush the bottom and sides of the pot to remove the film and to ensure all the stuck particles come away completely. Rinse well with hot water.
Option 1: After perfectly cooking rice, there will usually be rice stuck to the bottom and the sides of the pot and also a filmy residue. Shake some uncooked rice into the pot with a little dish soap and hot water. Scrub till the filmy residue and stuck particles come away.  If there is a lot of rice to remove, you might want to store it for next time. Rinse well with hot water.
