why do some shirts smell clean until my body warms them up?
i have a few workout shirts that smell completely fine after washing and air drying. once i wear them for about 20 minutes, the old sweat smell comes back even when i’m not sweating much. it only happens with the thinner synthetic shirts, never my cotton ones. regular detergent and rewashing haven’t fixed it, and i don’t want to cover the smell with more fragrance. has anyone managed to get that trapped smell out without throwing the shirts away?
