Aug 28, 2011· Not purifying. I'm not asking about purifying. I know that only Deacons and Priests may purify the vessels after Mass, and that's how it's done at our parish. My question is about cleaning the vessels after the purification. At our parish, the sacristans may do this. My question is, what kind of soap do people use? We have gold-plated cups, chalices, and ciboria.
