Hello there and God Bless!
I guess the title mostly says it all. I work as a lay server in the University I’m at, and in our chapel, there’s only one sink, the sacrarium. I’ve noticed that the sacrarium is used both to rinse the chalice and the paten, but also, though less frequently, to clean these vessels with soap and sponge. When we clean the vessels, the soap residue goes down the sacrarium. So my question is, is such a practice alright? Or should the sacrarium be reserved to just rinsing the vessels? Thank you, I appreciate any feedback :).
