# If a vessel was used even once for Chametz it needs to be cleansed to be used for [[Pesach]]. A bread knife which was once for cutting a Chametz food that was hot such as warm cake, warm breaded-chicken, or used to stir chulent. A teapot needs be cleansed because it probably touched Chametz when it was warm. <Ref> Yalkut Yosef (Isser VeHeter vol 3 pg 470) </ref>

# 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.

# The Ashkenazic minhag is not to kasher glass.<ref>Kitzur Shulchan Aruch 116:13</ref> According to Sephardim, one never needs to kasher glass, as it does not absorb. Rather, one must wash it thoroughly. The same is true for Pyrex and Duralex.<ref>Yechave Daat 1:6</ref>

# You don't need to wait 24 hours since the grates need [[#libun]] to be koshered. For a gas stove put a pot on top of the grate so that the fire spreads out and leave it on for a half hour to an hour. For an electric stove you don't need to put a pot on top of it since it'll get hotter evenly so you only need to turn it on for 10-20 minutes.<ref> https://www.torahanytime.com/#/lectures?v=106099 Rav Shmuel Fuerst (min 14)]. The Mishna Brurah 451:34 writes that really the reason that grates need to be koshered is a chumra of chametz since a pot doesn't absorb from another pot without liquids in between. After the fact if someone used grates without kashering them it isn't an issue.</ref>
