Once a week for us, too.

Yeah, I like clean sheet day. And, someone told me today that even when you shower, your skin's oils are in the sheets over night. I don't know, though, like I said, I'm not really afraid of germs too much. I know sheets are dirty even when they don't smell, but, I used to not care.
