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 Pesah.
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 Pesah, or putting them through a dishwasher. One opinion is that it must be kashered. After a thorough cleansing, there should be water boiled in them which will overflow the rim. The other opinion is that only a thorough cleansing is required.
