My hubby uses All with no dyes or scents, so that's what I use for the piggy laundry from time to time, but typically I use half a cup of vinegar. I also put vinegar in for the fabric softener spot in my washer. It reduces static, neutralizes odor, and makes the fabric softer than it would without it. I've also snuck it into my hubby's wash and his clothes don't come out so stiff, and he is none the wiser.
