Remove the bowls, drip tray and any other components from the steamer and wash them thoroughly in hot, soapy water. Rinse them with water and dry them with a towel.
Cover the basin with a lid and boil on High heat for 10 minutes. After 10 minutes, pour out the hot water and discard the lemons. Using a little soap, wash and rinse the steamer basin well. It is now sparkling and clean.
