I have used vinegar in the wash as well as 20 Mule Team Borax. They both can get out some pretty raunchy 'My-guy-worked-all-day-in-the-heat' smells. If your washer hasn't been cleaned in some time, you may want to run your washer empty with only hot water and Borax to clean the washer first. That should ensure no added odors are added to the fabrics.
