# There is a question if it is possible to kasher plastic utensils. <ref>Rav Shimon Eider in Halachos of [[Pesach]] (p. 137) rules that one may not kasher plastic utensils for [[Pesach]] based on Igrot Moshe 2:92 who doesn’t allow kashering synthetic rubber since it is a new material that wasn’t discussed by the Rishonim. See however, Chazon Ovadia (p. 151), Minchat Yitzchak 3:67, Chelkat Yaakov YD 45, Tzitz Eliezer 4:6 who allow kashering plastic.

# Microwave which heat up food like an oven are cleansed like an oven by having it cleaned from all Chametz, left unused for 24 hours, and then heated to it’s highest temperature for an hour. <ref>Yalkut Yosef (Kitzur S”A 451:10) </ref> | # Microwave which heat up food like an oven are cleansed like an oven by having it cleaned from all Chametz, left unused for 24 hours, and then heated to it’s highest temperature for an hour.<ref>Yalkut Yosef (Kitzur S”A 451:10) </ref> | ||
# Microwaves which are used to heat up food by radiation then if the microwave walls are made out of metal, many hold that one can kasher the microwave by cleaning it thoroughly and boiling a cup of water in the microwave until it steams. If the walls are made out of plastic, many say that one can follow the above procedure and then cover the food put in the microwave on [[Pesach]]. <Ref> The Mishna (Avoda Zara 75b) writes that utensils, which absorbed the taste of forbidden food through fire, can be purified through Libun. Tosfot (Chullin 8a s.v. SheLivna) explains that since when chametz is absorbed into the utensils before [[Pesach]] the chametz taste was permitted, utensils that usually required Libun, can be kashered with Hagalah. The Ran (Pesachim 8b s.v. Devarim) explains that the Rif considers chametz taste to be a forbidden taste since it has a status of chametz even before [[Pesach]]. Although S”A and Rama 451:4 rule stringently, the Mishna Brurah 451:32 notes that in some cases we rely on the lenient opinions. | # Microwaves which are used to heat up food by radiation then if the microwave walls are made out of metal, many hold that one can kasher the microwave by cleaning it thoroughly and boiling a cup of water in the microwave until it steams.
