Used glass restoration stain removed on my shower door. Followed directions exactly. After leaving the solution on the glass for 10 mins I scrubbed it and scrubbed it. I sweat my butt scrubbing it! Then I rinsed it off and wiped it while rinsing… it STIIL has water stains on my shower door. The product did work, and got my shower door much cleaner than it was, however, for the amount of scrubbing I did, I was expecting it to be crystal clear…
