Auto glass is usually never maintained. Consequently it becomes stained by mineral deposits. These look very bad and impair vision. The Envirosafe product is able to rub it off by hand with paper towels. Or you can use small three inch soft wool pads with a rotary machine. Slow is best.
Have you ever looked at a couch bus? They are huge. Half of the surface area is glass. Further every bus that I have ever seen has hard water stains covering every square foot of glass. This is usually from regular washing and rinsing with ground water that is loaded with minerals. But all of this glass can be polished so it is crystal clear. There are few hard water spot removers that will remove average spots by hand without scratching, and without the use of acids or other unsafe chemicals. You will know that all of the spots have been removed if you fog the glass with your breath. The fog will form an even film of water. Any left over minerals will show up in the fog. Even "invisible" deposits will show up in the fog film. I typically use this method to show silica deposits left by water fed pole window cleaning. The TDS of the cleaning/rinse water might be zero but it could still have silica.
Boats, especially yachts, have bad spots from ocean water. Which can be very difficult to remove. Further subway trains will develop thick organic stains from atmospheric pollution. But the Envirosafe Spot Remover will take this off too. There are many different stains on vehicular glass that should be removed.
The Envirosafe product sells for 15.95 per bottle. But you can check out their website and order direct.
