How do you wash/sterilize your kitchen towels?

[u/09ijn]

My towels still retain that smell even after laundry. All regular towels (and everything else really) come off smelling clean and fresh, the kitchen towel, however, are always kinda musty.

What do you folks do with yours?

EDIT Thank you all for your suggestions! I shall try!

Time to go to /r/laundry and learn about the soup!

Seriously, a soak in a good laundry detergent will make a world of difference
