Yes, lots of people like to make a paste out of baking soda and clean the inner pot with it. This helps to keep it shiny. To do this, make sure the inner pot is clean first (no grease or food in it). Then, sprinkle baking soda on the bottom of the pot. Use a damp sponge to begin scrubbing with the baking soda. If there isn't enough water in your sponge to create a paste, add about a tablespoon or so of water. Then, rinse it out and dry it.
