Do you have stinky pants? It might be your washer if Smelly Washer is to be believed. Apparently, detergents and fabric softeners can build up in the washer and create a foul odor. I didn't believe it until I asked around the office and a co-worker reported that it happened to him. Smelly Washer is a liquid washing machine cleaner. Simply add the mixture to your washer with your next load of laundry, and the smell is gone! Smelly Washer can be ordered on the manufacturer's web site.
