I got this because my dry cleaner somehow got bleach on my jean jacket (although they claim it was already like that when i dropped it off....) If you are going to spot treat denim, which is what I did, don't dilute it. wet the denim, shake well, dip a q-tip in the bottle, and dab on the small area. let it set 20 minutes and rinse with a little mild soap. then do it again right away, if the bleached spot is still noticeable. I sort of blended the edges out, too, so there wouldn't be an obvious line. two times did it for me. going to do the other two spots tonight. im very happy with how the first spot looks!
