Me? I really don't have much of a need for hair ties, but maybe you do. Guess what? They are probably loaded with bacteria. Are they cleaner that a toilet? That seems like the litmus test, but I won't go there.
Seems like the fabric absorbs sweat and bacteria during the day...makes sense. Think about it if you are working out at the gym or something.
Here's the simple solution. Wash them with soap and water. I know another thing to add to your list of things to do. At some point we have to ask ourselves "am I really going to get sick by keeping my hair out of my eyes?". I'm thinkin' just wash your hands once in a while and you're probably fine, but I'm not a doctor.
