I sweat; my clothes s.t.i.n.k.
Yes, I wear antiperspirant 😂. Yes, I try to wash my workout clothes the same day I sweat in 'em 😅. But, over time, some of my beloved items have acquired a certain...umm...reek that washing doesn't remove.
The solution: soak them in 1 part white distilled vinegar and 4 parts cold water for 30 minutes before washing 💦. This was just one tip I gleaned from "11 Ways to Get The Sweat Smell Out Of Your Workout Clothes" by Kristin Canning at the Women's Health Magazine website https://www.womenshealthmag.com/fitness/a27059552/how-to-get-sweat-smell-out-of-gym-clothes/
So I tried it. I mixed 2 cups of vinegar and 8 cups of water in a plastic bucket. It wasn't a lot of liquid (I didn't have any more vinegar on hand) so I soaked my clothes in batches. Then I tossed them in the washing machine. I added two-thirds my usual amount of laundry detergent (less is more when it comes to cleaning workout clothes as Kristin mentioned in another tip) and washed them. And woohoo!🤗 - it worked.
