I just used Tilex Soap Scum, now I have a horrible film on my shower door glass. How can I get rid of it?

I just sprayed Tilex Soap Scum remover on my clear, glass shower door, left it sit for 5 or 10min, then used lots of hot water to rinse off the door.
The stuff left beind a spotty residue over the whole door and I cant seem to get it off.
I tried just hot water on a washcloth, and then windex and it still doesnt come off.

How do I get rid of this stuff?
