Vinegar can be very effective--soak like colors over night in a bucket with two cups of white vinegar. Drain and wash as usual with hottest water cycle and a cup of vinegar with the detergent. BTW, when I use this to remove eau de German Shepherd Dog after my son and his dogs visit (washing machine, only) my laundry does NOT smell like pickles--just clean and fresh. Dry the fabric outside if you can. Sunshine is a germicide and mildew killer.
