Wash the plate carefully with warm water applied to both sides of the plate to rinse it well. If you have clear ammonia, you can do a mixture of warm water and ammonia (50/50 solution is suggested) and let the plate soak in that for about 10-15 minutes. Gently scrub with a stiff brush if you notice any deposits not coming off with water along. Be careful not to drop the plate or scrub off the silicon. Clean both the metal screen and the ceramic tile. Rinse plate in hot water and DRY COMPLETELY before reinstalling. If available, you may use a hair dryer to dry the plate. Reinstall plate, making sure it is inserted all the way and seated securely in its place. Reassemble, plug the unit into a grounded electrical outlet, turn it on and enjoy.
