Most of towels currently smell like dirty foot... IDK why! I always hang them up after use so they dry properly, and they are frequently washed and hung straight on the line. I never put them in a drier; I prefer the sun to 'bleach' them so they get a really good dry.
Nevertheless, they smell and I want to change that. Will adding white vinegar to the wash help?
Is so, how much? And do I still add in washing powder?
