Good point. How many bugs can survive the dryer? Probably none. Anyone who ever got sick from their clothes please raise your hand. Nobody? Well alrighty then.
Gotta Say, We have a new energy effecient washer and dryer. Didnt think much about it at the time but many things smell dingy/sour as soon as they get damp when worn. Only bleach seems to help but it has to be diluted and added in occasional measured amoints. Bottom Line: “Energy effecient” usually means “Doesn’t Work”
