Whatever I happen to have on hand. Using Persil now I think since I ran out of Tide. Bibs & Jersey's go in with whatever else is getting washed. Just did a load today in with the sheets. If I wore high dollar gear I probably wouldn't do this but with the inexpensive stuff I wear I don't really care and have never had a problem anyway. Only rules are to zip up all zippers and made sure not to let any of my wool socks inadvertently go into the drier.
