alt Hacker NewsI get exactly the same thing. It crept up on me over the past decade of a life where people commented I had to little to no actual distinctive smell, and alas, now I do. What will really make it come out is if I have 2 or more alcoholic drinks the day/night before. The smell reminds me of a friend/coworker from the '90s who didn't bathe regularly and P U.
Daily sweaty cardio is more than enough to control it for me as well. But if you can't, deodorants like Lume cover it up and as others have posted and there are soaps that work better on it than others. I occasionally put all my athletic clothing through a hot wash myself because as someone once said on BlueSky, all clothing is washer-safe if you don't care what happens to it.
Something that made a night and day difference to all my athletic clothing is adding laundry sanitizer to the wash load.
We noticed our running clothes developing this very strong sickly sweet/sweaty smell and it would not go away. Spent time deep cleaning the washer and dryer to no avail.
We now add Lysol laundry sanitizer (just 1 cap, not the recommended 2) to every wash load and the smell completely went away instantly.
I still don't know why all the clothing suddenly developed that smell - I went my whole life without needing to do anything special to my athletic clothes until then.
