# If a person cooked parve food in a meat pot and then dairy food was cooked in that pot within 24 hours of the meat the dairy food is considered non-kosher and the pot needs to be koshered.<ref> The Rashba (Torat Habayit 38a) writes that if someone cooks vegetables in a meat pot we can treat that cooking like a mini-koshering of the pot and it can be used for dairy afterwards. His proof is Rava in Gemara Avoda Zara 76a who says that cooking korbanot in a pot koshers it from its previous absorptions. The Rashba explains that cooking is only a mini-koshering if the absorption was permitted such as milk or meat or korbanot. However, it isn’t a sufficient koshering for a forbidden absorption. Raah Bedek Habayit 38a agrees with the Rashba and Orchot Chaim Isurei Machalot s.v. hachamishi, Rabbenu Yerucham 15:28 138b, and Tur 93:1 codify it.

Darkei Moshe 93:2 cites this dispute and in Rama 93:1 he rules like the Isur Veheter. Shach 93:6 holds like the Hagahot Shaarei Dura arguing that the lid is itself a kli rishon so the drop retains its status of iruy. Pri Chadash partially agrees with the Shach but only seems to forbid the pot and not the lid. Badei Hashulchan 93:1 s.v. vim hakisuy explains that the Pri Chadash holds that a drop doesn't have the ability to absorb taste and then transfer it. This is in line with the Chavot Daat 92:20 and 105:13 unlike the Yad Yehuda 92 (cited by Badei Hashulchan 92:8 s.v. ashtey kederot). Chavot Daat thinks that a small amount of moisture can absorb taste but not impart it because liquids also absorb tastes like foods and as such a food can't impart flavor to something else without a liquid or fat (S"A YD 105:7).</ref> Poskim are strict unless there is financial loss involved.<ref>Chachmat Adam 46:5, Badei Hashulchan 93:31, Laws of Kashrut p. 270</ref>

Rabbi Akiva Eiger 93:1 sides with the Taz. Darkei Teshuva 93:21 cites the Minchat Yitchak 16b who makes a compromise. If the lid was placed on the pot before it started to steam up one should be strict, however, if the pot was already boiling when the lid was placed on then one could follow the Taz.</ref>

However, one should be careful to make sure not to leave something that could spill or leak such as a milk carton over a meat food.<ref>Laws of Kashrut ch. 13 p. 350. Yalkut Yosef Isur Vheter v. 3 88:3 adds that one can leave the meat and milk next to eat other in the refrigerator as long as they don't spill upon each other but one should be careful about this initially. See however, the Badei Hashulchan 95:101 who writes that a person should designate areas or shelves in their refrigerator for meat and milk and not switch them. This is based on the Rama 95:6. Zar Hashulchan 95:73 agrees with the Badei Hashulchan.</ref>

# Parve food cooked in a meat pot is considered meat-equipment and according to Ashkenazim it shouldn't be eaten together with dairy but after the fact if it was cooked with dairy it would be permitted to be eaten. According to Sephardim it is permitted even initially to eat the parve food made with meat equipment with dairy.<ref>Shulchan Aruch and Rama YD 95:1. Gemara Chullin 111b cites a dispute between Rav and Shmuel whether a fish cooked in a meat pot can be eaten with dairy. The dispute depends on whether a taste imparted from a food into a utensil and back into a food is considered a significant taste. The conclusion of the gemara is that it is permitted.

===Dairy or Meat Spoon Used in Parve Pot===
# If a person used a dairy spoon to mix parve food in a parve pot then we should treat that pot like it is dairy. The same is true if a person used a meat spoon to mix parve food in a parve pot.<ref>Shulchan Aruch Y.D. 94:5, Shach 94:15, Taz (Daf Acharon 94:5), Chachmat Adam 48:3, Aruch Hashulchan 94:19, and Badei Hashulchan 94:53. The Shach and Taz both explain that the reason a person should use the parve pot that was used with a dairy spoon only for dairy is because once a person is going to establish it as dairy or meat anyway he should make it dairy since it accepted taste of dairy. However, in terms of principles of transferring taste, there is no concern of dairy taste in the pot since it is only nat bar nat that was infused into it.</ref>

* Hagahot Smak (213 n. 1*) writes that if a person used a dairy spoon and then a meat spoon with a parve pot that was cooking water the Smak held that the pot can't be used again, while the Rabbenu Peretz argues that the pot isn't affected since the transfer of taste from the spoons to the pot is only nat bar nat. In fact, there are three steps of transfer of taste making it three nat's (dairy to spoon, spoon to water, water to pot). The Kol Bo 106 s.v. maseh ba, Orchot Chaim (Hilchot Isurei Machalot s.v. maseh ba), Isur Vheter Haaruch 35:10, Hagahot Shaarei Dura 85:15 (Bar Ilan version 85:18), and Maharshal (Isur Vheter 85:2) record this dispute as well. The Taz (Daf Acharon 94:5) writes that the Rabbenu Peretz was only lenient when he was discussing a case that the meat spoon was used after 24 hours of the dairy spoon being used with the pot. If it was a case where they were both within 24 hours he would agree that the pot is forbidden. That justifies the Shulchan Aruch 94:5 and Rama.

* The Shach 94:15 (also in Kuntres Acharon 94:5) accepts that such was the case of Rabbenu Peretz however he would be lenient in either case. This is also the contention of the Isur Vheter Haaruch 35:11. Ultimately, as long as there are three nat's even those who are strict on nat bar nat would agree to be lenient and certainly after the fact. Therefore, the pot which had the dairy and meat spoon used with it sequentially is permitted. The Taz disagrees and explains that even though it is an example of nat bar nat, nonetheless one can't cause nat bar nat. If a pot is established as meat then it isn't make forbidden because of nat bar nat. On the other hand, since it was only made forbidden because of nat bar nat to begin with, it is established as ''lechatchila dairy'' and when the meat spoon is used afterwards it is ''lechatchila meat'' and that is a contradiction. Therefore, the pot can't be used for meat or dairy.

# Some permit using a steam jacket kettle even if that steam was previously used for non-Kosher.<ref>Rav Schachter in OU document K-36 is lenient on using a steam jacket with steam that was used for forbidden foods because steam isn't the same as vapor. Steam is a gas and water vapor are droplets in the air ([https://www.quora.com/What-is-the-difference-between-steam-and-vapour Quora.com]). Since steam isn't a liquid it can't absorb taste. He adds that since the metal pots don't let beliyot through the pot perhaps that can be used as a factor to be lenient.</ref>

## After the fact, if the meat dish had a piece of meat on it or even just grease and the dairy dish was clean, and they were washed together in the sink, both dishes are considered non-kosher. In a case of a large loss some say that the meat dish would be considered kosher, while the dairy would be considered non-kosher. The same is true of the opposite case.<ref>Shach 95:20 isn't certain whether we assume that an iruy cooks so much to infuse the taste of the meat into the dairy dish and then extract the non-kosher taste from the dairy dish and infuse it back into the meat dish. He concludes that we should be strict unless there's a large loss. Rabbi Akiva Eiger on the Shach 95:20 is strict even if there's a large loss if there was more than one pouring.</ref>

# If one is cleaning meat dishes in the same sink in which one cleaned milk dishes, if there's still some dairy remnant in the sink, it's forbidden to pour hot water there because at the time one pours the water the meat and milk are halachically cooked together even though one has no intention of using those remnants. <ref>Sefer [[Kashrut]] HaShulchan (Baser BeChalav 6:3) quoting Sh"t Yabia Omer 5:3 </ref>

* Rav Moshe Feinstein (Igrot Moshe OC 1:104, OC 3:58, YD 1:28-29, and YD 3:10-11) is lenient to use a dishwasher for meat and milk dishes consecutively with different racks. His reasoning is that the only concern of taste from the dirty dishes is Nat Bar Nat and therefore doesn't render the dishwasher meat or milk. He explains that it is permitted even initially and isn't considered like creating Nat Bar Nat. Also, he says that there is probably sixty times the beeyn in the actual pieces of leftovers on the plate. Yet, he says that a person should use different racks for meat and milk out of a concern that a piece of meat or milk got stuck onto the rack and taste directly got absorbed into the racks.</ref> Sephardim only allow using one dishwasher for meat and milk if they are used in different shifts and the dishes are first rinsed to remove the large pieces.<ref>Yalkut Yosef (Otzar Dinim L'isha p. 618), Yalkut Yosef (Isur Vheter v. 3 p. 485) only allows consecutive cycles. Yabia Omer YD 10:4 allows meat and milk dishes together. Rav Ovadia himself in the new edition of Yabia Omer 10:4 fnt. 6 added that it is better not to follow his teshuva to do it at the same time. Rabbi Assayag and Rabbi Wiesenfeld in Kashrut in the Kitchen Q&A p. 91 rule like Yalkut Yosef.

* Shaarei Shalom on Piskei Ben Ish Chai Basar Bchalav p. 143-5 is strict for all dishwashers even one after another. If the first cycle is with soap he is concerned for the fact that noten taam lifgam is only after the fact. He quotes Tzemech Tzedek 61, Minchat Yakov 57:26, and Shulchan Gavoha 95:7 who only allow the case of using ashes to clean dishes (S"A 95:4) after the fact. Also, if the first cycle is without soap there is an issue because if the dishes are dirty everything becomes forbidden and if they're clean we don't rely on S"A 95:3 initially as Shach points out.
