Warming Rice in a Rice Cooker

Before, I get trouble washing the rice cooker pot because of toasted rice sticking stubbornly inside.  I had to submerge the pot in water for longer time to soften it for me to be able to wash it thoroughly. Besides, heating the rice on a pan, you will need to use oil unless you have a stoneware or other nonstick pan - not so healthy and if fried with garlic does not go well with soupy dishes unlike the steamed.
