Film on interior of windshield

I see this more on the Prius than I have on other cars. I do not know if it is just the design of the sloping windshield or what. I have to clean the inside of the windshield more often. The best I have found is a damp microfiber towel to clean it and then go back over it with a dry towel.

 

Windex, paper towels, and elbow grease seem to be the solution. I don't know the cause, some have speculated that it may be gassing from the interior plastic. It seemed to be worse when the car was new.

I haven't been a smoker for decades but if I remember correctly cigarette smoke used to cause something similar but much worse.

 

I've been using 409 glass & surface cleaner to remove the film. I stopped using Windex when I tried the 409 cleaner.

 

I really like the Invisable Glass (aerosol) for the inside window surfaces. It works extremely well. On the outside, I use rain-x.

Another vote for Stoner Invisible Glass. I use it on all my cars and household windows / mirrors. (With a dog, I do some windows weekly.)

 

So I'm not the only one with this problem! I use shop towels (microfiber) and Napa Glass Cleaner with Ammonia. I think the problem arises when I have the windows open, but I am not sure why. In addition, I have become careful to turn on the air conditioner when it is raining substantially; the insides of the windows seem to mist up very readily.

 

Advance Auto just put Stoner Invisible Glass on sale so I stopped yesterday and picked up a couple of cans. I will give it a try this weekend.
