My son recently started working at a meat processing plant, turning pigs into bacon, balognia, ribs, hams, etc. The smell he brings home is overbearing, not only does it stay in his laundry, it lingers in the washer and invades all the laundry. I now run the washer with on gallon of vinegar and no laundry to clean the washer each time his laudry is done to keep the rest of the laundry odorless, but there's got to be a better way. I've tried all kinds of over the counter soaks, sprays, and additives, but the odors persist in his laundry. We're talking odor from the remains of the pig that cannot be processed! Any suggestions?
