How to eliminate that permanent BO scent from sons athletic shorts?

There is a product called Odoban which I used to purchase from WalMart...I don't know if they still carry it or not.

You can buy it online...Here is a link...

But you can also try soaking them in Lysol Odor Sanitizer which you can probably buy at the grocery store.

Soak in vinegar and a bit of baking soda. Even a half hour or so should work. If not do overnight in a tub or bucket, then wash as normal.

Use vinegar in the washer. It takes yellow armpit stains out also.

I use Tide Sport laundry detergent. I have a son that always has BO and this does get the odor out, I also use vinegar in the softener cup, so far so good.

try hanging them on an outside clothes line and letting the sun and the wind do their job on them.

Put teabags in his she’s and put his shoes on the windowsill to air

same with shorts
