Sometimes if I'm really sweaty or if I haven't showered in a couple days, I'll notice that the soap suds smell different when I'm lathering up. Like, it smells bad. It doesn't affect the whole bar, it's just while I'm washing up. I buy different kinds of soaps with nice scents but is there something about body chemistry that is making this change happen? Is there a way to fix it? This has stumped me for all of the pandemic and I need to know the answer. Halp me, oh Metafilter!
