I had some pretty bad ones and i tried tons of different polishes and rainx, nothing worked.

I put some coke on a microfiber cloth and wiped in it the window. Finished off with Lusso glass polish and low and behold the combo worked.

Just thought I would share in case anyone else is running into the same problem

 

Thanks for the advice! Im not surprised this worked Coke burns through anything

 

how about hard water spots on doors and stuff? Damn the sprinklers, its practically covers my whole right side.

 

I've heard of this before, the phosphoric acid in it is the reason. Though I don't like the thought of putting coca-cola on my car

I'll stick with my Sonus glass polish

 

coke or coca-cola? wouldnt the sugar be sticky?

 

, i pretty sure he is talking about coca-cola,

it's sticky if you let it dry. don't let it dry.

 

Since it's glass a mild acid should be ok but I wouldn't use it on bodywork. Lemon juice is also a mild acid and should have the same effect.
