I buy new clothes and wear them for 2-3 months. I wash them several times during this period. The clothes don't smell fresh anymore, even after washing.
The smell is like sweat or ammonia or something else. The most unpleasant smell comes from polyester clothes which I use for running, which is why I think the smell is due to sweat.
I noticed that if I dry them quickly after washing the smell is not as bad, but if the clothes stay wet for a longer time they smell much worse.
I have tried changing the detergent but the smell only changes and does not go away.
Any ideas to remove the smell?
