Worked on 50-year-old stain!
This was a baby gown probably from the 1940s or 50s.  It was the baby "spit-up" that was staining this very sweet looking dress.  Regular laundry detergent didn't remove it, so I knew Biz had enzymes in it, and that would probably do the trick, and it did, it removed that over 50 year old stain!
