Shalom, It’s ok to use milui v’irui for koshering glasses (used with not kosher wine) from not kosher to kosher? leitraot, Many thanks.
Shalom, Glasses that had non-Jewish wine in them need only to be washed well three times. They do not need any other form of koshering. (See Shulchan Aruch Yoreh Da'ah, 135,1, and Kitzur Shulchan Aruch, 47,16) Blessings, D. Sperling.
