I’ve had a container of this for years, but saving a white cardigan made me write this review. There was a huge laundry OOPS and a white, knit cardigan ended up in the machine with new, dark denim jeans. We all know how badly dark denim runs, so no surprise to see the sweater was a horrible, splotchy mess. We caught it before going into the dryer, & mom told me to immediately grab oxiclean powder, dissolve it in a bucket of cool water, soak the sweater for a while, squish the water out, then make a fresh bath of oxiclean & cool water, & put the sweater back in overnight. I was amazed when I couldn’t find a single trace of blue, after a thorough rinsing.
