The big season clothes switch - how to freshen?

[Alalalalalongalalalalalonglonglilong]

That's it really, what should i do with all my T shirts. They are crinkly and smell a bit musty but only a teeny bit. Should I hang them out to air, then iron, iron only or wash everything? I normally don't wash but maybe the bags were not so good this year. What does everyone else do?

I'd rewash them. That musty smell on stored clothes is caused by bacteria.

If they smell musty, I would definitely wash them.

Thanks, I did not know it was bacteria that caused the smell.

I've just put mine on a quick wash with a tiny amount of detergent
Hopefully I'll get to wear them soon!

A quick rinse with a slosh of vinegar, air dry and iron and you will be as fresh as a daisy.
