The instructions say to leave this product on for 15-20 minutes. I never leave it on that long normally. I was impatient when I started using it years ago, and rinsed it after 10 minutes. I found it had done most of it's work, and only had to spot remove patches of bluing.
So now I check it about 10 minutes in, and if I wipe some off and if it's not done I simply cover the spot I wiped clean, and let it continue.
I have no idea why this worked so well, but I'm certainly glad it did.
