Hey, Sorry to hear you didn't see much of a difference. I thought I would help with a few notes on how to use our oxygen bleach to get the best results. The main ingredient is Sodium Percarbonate, it's best activated with some heat. So for best results, soak it in tap hot water for about 12 hours (it works better with time). And a similar tip for in the wash, you get best results from 40 degrees and up. It will work on cold washes too, but maybe not as dramatic. I hope this helps you get better results.
