I can't find it either after recently trying everything even the high pressure cleaner to remove tanin stains from outside tiles. I had one last shot and I used ajax powder with a scrubbing brush and it came off easily! And I also found the best thing like you to clean the bottom of pans and everything stainless steel was ajax and scotch-brite pads. I think everyone buys that toxic spray now that is mostly useless because they like the fumes from it I guess as water and dish washing liquid cleans better.
