This is a polyester shirt from the Uniqlo airism range.
I like the shirt, but recently it got these spots on it? Is this from sweat?
This picture is after washing with lots of detergent.
Is there a way to get it out?
It seems to disappear after a while, but comes back after washing.
The shirt also smells ok, but after wearing it for a short while it starts smelling.


All my other clothes from the same wash are perfectly clean, just these older synthetic shirts have this. I think the drain is ok, pretty new machine too.
