Minimum acceptable rinse temperature
Tap cold in my area right now is around 45-50F (7-10C). Is there much to be gained by rinsing at, say, 65F (18C) instead, if I could snap my fingers and make that happen? Of course, my washer only allows cold rinses -- I believe tap cold.
What are the objectively defined differences between rinsing at various temperatures? Would three 45F rinses be as effective as two 65F rinses? What else should I know, also?
Thank you for any thoughts you can spare on this subject.
