# 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>

# If one isn’t going to put any hot food on the counters on [[Pesach]], it is sufficient to clean the counters very well. If one is going to put hot food on the counters on [[Pesach]], one should clean and cover the counters. Regarding kashering the counters, see the footnote. <Ref> The Tur and S”A 451:20 write that the minhag is to pour hot water on the tables and cabinets used for food during the year because sometimes hot liquid chametz spills onto them. The Magen Avraham 451:38 quotes the Maharil who records the minhag to cover the tables and cabinets after this kashering procedure because perhaps some actual chametz was stuck onto the table or cabinet.

* Kaf HaChaim 451:233 notes that wooden tables which one always eats on with a tablecloth don’t need to be kashered and one should simply remove the actual chametz and wipe down the surface. Rav Mordechai Willig (“Shiur 64 – Pesachim” min 80-82) says that strictly speaking this is also true for countertops on which people don’t put chametz directly. [https://www.dropbox.com/s/tgm9gww30vkgw7s/_Rabbi_Willig_Shailos_03_25_2020_.mp3?dl=0 Rav Willig (min 36)] said that it is best to cover the counter tops. Rav Hershel Schachter [http://www.ou.org/community_services/video/67558 (OU Pre-Pesach Webcast 5769, min 11-13)] adds that one could either kasher the counters or cover them, but if one isn’t going to put any hot food on the counters on [[Pesach]] one could simply clean the counters well.

#According to Sephardim, dentures need only be cleaned well.<ref>Yechave Daat 1:8</ref>
#According to Ashkenazim, some say that dentures should just be cleaned well, while others require hagalah. A compromise view is to avoid eating hot chametz with them within 24 hours before pesach and clean them well without hagalah.<ref>
* Dvar Charif ch. 7 fnt. 101 notes that some of these reasons don't help for if a person eats a dvar charif on pesach and the taste of the chametz comes out of his teeth.
* Reasons that dentures don't need to be kashered for pesach: our dvar charif's today aren't the ones of the gemara (Moadim Uzmanim cited by Dvar Charif p. 120), the dentures are smooth like glass and don't have beliyot (Minchat Shlomo 2:50), the taste of the food is so pagum because of one's breath and saliva that it can't even be reinvigorated by a sharp food to taste good again (Minchat Shlomo 2:50), the teeth aren't as sharp as knives (Orchot Rabbenu v. 2 p. 27-9). The Steipler said that because of the issue he advised not eating hot chametz within 24 hours of the time when chametz will become forbidden. Some of these reasons apply to filings and braces. [https://www.dafhalacha.com/wp-content/uploads/2019/12/DHYB-Monthly-Bulletin-Kislev-5780-English-11-29-19-EMAIL.pdf Dirshu (Kislev 5780)] summarizes some of the poskim on this topic. Rav Shmuel Kamenetsky (Kovetz Halachot Piskei Rav Shmuel Kamenetsky Pesach p. 127) is lenient on dentures, fillings, and braces no to require hagalah as long as one didn't eat hot chametz or dvar charif of chametz within 24 hours of the time of chametz becoming prohibited.</ref> According to Sephardim, dentures need only be cleaned well.<ref>Yechave Daat 1:8</ref>
