What stinks?!!!

Here's the story. I have a few towels that every time they get wet they stink to drive you outta the house....kind of a sour smell. What is that ? Moldy almost. None of my other towels or clothes, sheets, etc. smell like that, so what is it ? Yeah, they are very old and have been used a million times.

I am going to try soaking them in hot vinegar water this weekend to see what happens. This occurs even after I wash them, right out of the dryer. Heeeeeelp !

If the vinegar trick doesn't work, they'll go to that great towel rack in the sky.

Suggestions ?
