Then, oven and range should be heated as hot as possible for a half hour. If there is a broil setting, use it. Continuous cleaning ovens must be kashered in the same manner as regular ovens. Then the oven should be turned on until the water disappears. A microwave oven that has a browning element cannot be kashered for Pesach.
Authorities disagree as to the method for kashering drinking utensils.
One opinion requires soaking in water for three days, changing the water every 24 hours. The other opinion requires only a thorough scrubbing before Pesach, or putting them through a dishwasher. If the parts are not removable, the appliance cannot be kashered. If used with hametz, they should be thoroughly cleaned and covered, and then they may be used. A metal sink can be kashered by thoroughly cleaning and then pouring boiling water over it.
