And I’m pretty clean each time too so it’s not exactly collecting a ton of dirty. If it’s used for something other than me fresh out of the shower then it goes straight in the wash. Otherwise it gets washed when I do laundry each week.
You’re not clean, though. You’re really, really not. You’re cleaner, but humans are disgusting and a residential shower is in no way getting you anything close to actually ‘clean’. You don’t have to be insane like I am and swap them out every shower, all the literature I can find says 1-3 days is probably fine, but please please get a couple more towels and swap out for a clean one every few days at least, right now you’re just culturing some very nasty bacteria and then rubbing it all over yourself.
