> who sometimes do the Yekkishe washing … also sometimes eat milichigs three hours
is this a major kulah? you make Kiddush, you wash, you eat challah, just in a different order. You also make kiddush with clean hands. Just had in the daf, Kohen Godel reads one of the parshiyot by heart instead of a scroll to avoid tircha d;tziburah, surely you can say kiddush with clean hands. I’ve seen people doing it not as a routine but in certain circustances, say in a sukkah where coming in and out takes long time.
