We have solved the problem. At first we tried this and it did not work, but here is what we did. Using Vinegar a little water and baking soda. We mixed very little backing soda in the liquid (mostly vinegar)to create a very light feel to the texture so the baking soda did not scratch the shower. We used a teflon scrubber and applied and scrubbed in a circular motion. After 5 min we rinsed off. Please note, that if you wait to long the mixture will thicken and become too rough to use and will need further dilution with additional vinegar. On the glass we used WD-40, then let it sit for 5 min and scrape off with a razor blade.
From this point on we hope to use a liquid cleaner for maintenance. (Better Life Tub and Tile cleaner....we found on Amazon)
