Cool, I said it was a random question. Yeah, I usually do it once a week, like I said. I'm just grossed out by sleeping on dirty sheets, so, I probably should wash them more often. When I did start cleaning my sheets once a week, I noticed that my skin improved, and, it's an easy chore. Rip 'em off, throw 'em in, put 'em back on. It's the only one that I really don't mind, because I hate folding laundry, blech.
