Hello Rabbi/Rav, I have a few questions! I very much appreciate you answering! Is it okay to touch a mezuzah with unkosher residue after eating? Does saying "baruch shem kevod malchuto l’olam va’ed" cancel every time I said His name in vain even if I don’t think of every individual instance? Best

ב"ה Shalom I'll start with the second question. Saying "Baruch Shem" only refers to the individual instance said before, as it to rectify saying G-d's name in vain, after the fact, when it was immediately before. In regard to the Mezuza, I'm trying to understand why you ask many questions about non-kosher residue on one's hands, while today everybody has a tissue or a napkin handy, or a wipe or even a sink to wash one's hands, so the residue issue does not have to exist. So I am wondering, perhaps your question is, and please don't get offended if I'm misinterpreting ,is it proper to kiss the Mezuza on the one hand, while a person hasn't overcome yet their urge to eat non-Kosher. Meaning, the question is not a kosher issue. So, if I'm wrong in my understanding, I apologize and please correct me. However, if that is what you meant or somewhat close to it, then I would have to say, that if a person is trying to keep more of the Torah and become closer to G-d, then that the person has to pursue the positive and not let the things which have not yet been overcome be a hindrance. All the Best
