Thank you so much for your note with additional information on how to best use your product. I bought the yellow and green Scotchbrite pads, and used them several times in conjunction with your product. I’m very happy to say that after several uses, there is only a small shadow of a ring in both toilets. Later I’ll do a number of additional treatments with the Scotchbrite pad, and may be able to remove even that remaining shadow.
I’m so pleased that the two toilets are 90% better looking, after I’ve struggled to deal with this for years. I really appreciate and thank you for your note, and will leave a positive review on your website. Thank you so much.
