My wife has a strong sense of smell. Perfume or other odors make her ill. So it is a sad side effect of bringing home numerous stacks of thrift store treasures, that she often complains of the stink.
It’s a bit of a problem. Often it is mold. Records that have been sitting around uncared for, for who knows how many years. Some, like my wife, find them rank. “Ewww, what’s that smell??!” she yells. Oh, I got some new records today, sorry.
I call them record farts. It doesn’t seem to be the vinyl, but the cardboard that does it. Next time you see an oldie, open up the outer sleeve and take a whiff. Whew! It’s weird. And kinda stinky.
