HELP! Lent a cotton shirt to a friend and now the armpit area constantly smells like sweat.
So I lent a pure cotton, good quality, around 1-1.2mm thickness fabric shirt to a friend who said they used it mainly indoors and didnt sweat much. But the armpit and surrounding area now strongly smells of pungent sweat that makes you barf.
I have tried these combos (all separately):
Warm water + salt/baking soda
Cold water + salt/baking soda
Vinegar + warm/cold water
Colour safe bleach in cold water
All of these were followed up with a wash and rinse cycle in the machine with a heavy duty liquid detergent.
Norhing seems to help, but I dont want to throw this away. Also the smell is too strong so I cant even donate in good conscience.
