I used to use the CVS sterile cotton. I keep getting some throat irritation and the first 15-20 hits always had a hint of band-aid flavor which I perceive to be a result of whatever it has been "bleached" white with. Just because it is labeled "sterile" doesn't mean chemical free. Just sayin'.
I switched to unbleached organic ("100% cotton that has not been chemically treated, bleached or pigmented. Raised without the use of chemical fertilizer or pesticides to ensure pure, safe quality")cotton several months ago and have not had any issues with throat irritation nor odd flavor from the cotton. I don't feel the need to boil
this cotton. YMMV....ya'll.
That's a really good point. Choice of cotton (yarn, wool balls, qtips, sterile, organic, etc.) REALLY is a YMMV. I don't mind my "whatever this is made from or what's been done to it" standard cotton ball, non-boiled. My brother, however, can only use organic, like you. I KNOW what sterile rolls smell like (that BAND-aid smell, yuck), and know for me, that is not a suitable choice.
However, next cotton ball purchase, I may just grab the organic/unbleached bag, just because it makes better sense for me. I say everyone needs to try out different sources, and decide which tastes best to them. All cotton is not "created" equal, right?
