PURIFICATIONS

237. Whenever a particle of the eucharistic bread adheres to his fingers, especially after the breaking of the bread or the communion of the people, the priest cleanses his fingers over the paten or, if necessary, washes them. He also gathers any particles that may fall outside the paten.

238. The vessels are purified by the priest or else by the deacon or acolyte after the communion or after Mass, if possible at a side table. Wine and water or water alone are used for the purification of the chalice, then drunk by the one who purifies it. The paten is usually to be wiped with the purificator.

239. If the eucharistic bread or any particle of it should fall, it is to be picked up reverently. If any of the precious blood spills, the area should be washed and the water poured into the sacrarium.
