**An EMCH wipes the rim of a cup with a dry cloth. This spreads any germs around that rim.**
If the Extraordinary Minister puts the cloth, unfoled between their forefinger and middle finger, and pulls down a new place to wipe the rim of the cup, germs are not spread. I have even asked people to wait, while I turned the cloth over and started on the back side of it. I also inspect the inside of the cup and sometimes (Usually always) wipe it too, becuase some older people have some backwash. It’s a race sometimes to get to the backwash before it gets to the wine, though! LOL! My purificators are always all used up and usually as wine-stained as the priest’s!
I forgot one step in the giving of the cup. I always turn it a quarter of a turn. It bugs me when EMHC use the same spot to wipe the cup. Maybe I’m extra vigilant, but I used to work with young children!
