Friend came round this evening in a pair of sports leggings that absolutely stank - really musty. She admitted that she has a tendency to leave clothes in the washer for 24 hours before getting round to tumble drying, which I would presume is what caused the smell. She sat on my sofa and then the end of my bed whilst she was here, and it's making me want to change the sheets and wash the cushions!
Personally I would always rewash things in that situation, or in general if my clothes still smell after drying - because I assumed that the musty smell was mould and that I therefore needed to from a health perspective (is it?). But is that what everyone else does? My friend is sure she's in the majority in not having time for that!
