Reply To: Can't Eat By In-Laws Who Eat Gebrochts on Pesach

Both are Minhagim. Shalom Bayis probably trumps (relatively) late Minhagim. And even if it doesn’t (and I understand completely why it doesn’t), it would seem too much of a stretch to extend it to Blios in the Keilim (especially when it’s explicit in Poskim that we’re not Choshesh for Blios of Kitniyos).
