My mother is an Extraordinary Minister of Communion and has to wash the altar linen used during the various Masses. Out of curiosity, and preventing possible sacrilege, what is the best and most respectful way to wash corporals and purificators?
The ideal, classic, way is for the priest to do the first rinsing. That water should go down the sacrarium or poured onto the ground.
There is a good booklet on the care of linens.
