# An electric or gas oven should be cleaned from all specks of Chametz and left 24 hours unused.

Chut Shani Pesach 10:2 writes that the minhag isn't to kosher such an oven but after the fact the koshering is effective. | ||
* Rav Ovadia Yosef explains that according to many rishonim chametz is considered something which is permitted that was absorbed in a utensil that only becomes forbidden over time and as such even items which normally would require libun can suffice with hagalah. Even though Shulchan Aruch O.C. 451:4 holds like the rishonim who hold that chametz is considered like a forbdiden taste all year since on Pesach it will be forbidden and as such libun is necessary on utensils used over the fire, nonetheless, for utensils which can't be koshered any other way and it is difficult not to use the oven all of Pesach, one can rely on the lenient opinion. See Rav Ovadia's responsa for his lengthy explanation. | * Rav Ovadia Yosef explains that according to many rishonim chametz is considered something which is permitted that was absorbed in a utensil that only becomes forbidden over time and as such even items which normally would require libun can suffice with hagalah.

* Rabbi Soloveitchik offered another reason to be lenient. Since chametz only got absorbed through a certain temperature, those absorptions can be removed in the same way that they went in, which is certainly less than the maximum temperature that the oven can reach. This seems to be at odds with the Pri Megadim E"A 451:30 who holds that libun needs to be a certain temperature to burn out the forbidden tastes, but it is supported by the Arugot Bosem 119. Igrot Moshe YD 1:60 s.v. aval and Or Letzion 3:10:2 agree with Pri Megadim. | * Rabbi Soloveitchik offered another reason to be lenient.

* 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. 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. | * 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.

# One should kosher one's table by pouring on it boiling water or cover it.<ref>Shulchan Aruch OC 451:20 writes that one should kosher one's tables since often one spills soup on it. Isn't the majority of use of a table for cold? | |||
* Rav Yitzchak Yosef Marechet Hashulchan v. 2 p. 310 answers that really this is a chumra and that's why the language of Shulchan Aruch is that it is something people usually did but not that it is necessary. | |||
* Megilat Sefer Tarovet p. 271-2 writes that the majority use is defined by whatever the utensil is designated for and potentially it could be designated for multiple uses. Regarding tables since the spills happen because you are using the table to hold food that is also part of the use of the table. Binat Tzvi p. 78 and Rav Azriel Auerbach in Bnetivot Hahalacha 342:292 agree that spills are including in the majority use since they come because of the regular use. | |||
* Chut Shani Pesach p. 125-6 based on Gra answers that it is a utensil that is designated to be used for iruy. The fact that is used for cold doesn't relate to the use of spills since when it is used for cold or to hold a plate it doesn't absorb anything. Therefore, its use in terms of absorptions is only for spills and as such its majority of use requires it to have hagalah with iruy. However, he is troubled by Shulchan Aruch 451:25 who says that cups can just be cleaned since they are used for a majority of cold. He simply posits that if they were ever used for hot they couldn't be used without koshering. | |||
* Darkei Chachma 74:3 has another theory. Since spills aren't part of the use of the table they can't be judged as part of the majority or minority use. | |||
