I usually use Armor All Glass Cleaner , spoke with a couple tint guys they said to give Stoner Invisible Premium Glass Cleaner in the aerosol can a try. I tried it this morning it's the best one I've ever used. Spray on & wipe off no streaks just clean windows, it comes out as a white foam so you can see where you've sprayed it. Going to try it on an old eisenglass window to see how it works a canvas shop told me it's fine to use. It's only $4.00 a can at Freddy's.
