When a fleece I often wear during outdoor activity would get wet and I couldn’t let it dry sufficiently, it would sometimes develop that putrid odor that results from extreme bacteria build-up. Then it was time for a good washing, of course. But I found this difficult in my building’s a communal laundry, which only has “high efficiency” machines that appear to just spray the clothes with water. I found myself running the fleece through cycles multiple times to effect a sufficient cleaning. High efficiency?
