Best Glass Cleaner? Staining on windshield

[zipdoa]

Can't get these streaks out of my windshield. Tried a light abrasive scrubber + windex - no go. Almost looks like armorall was sprayed on windshield and left to dry...

Any recommendations for a product that will remove this? was considering this GTECHNIQ G4 Glass polish

I swear by Invisible Glass, but for that you might want to try 99% isopropyl alcohol instead.

I've used the really light steel wool on my windshield to help remove old coatings/shit. Might help. Or you'll need to compound it off somehow.

Easy to fuck that up too though, if you are an ape like me.

000 steel wool with glass cleaner or a soapy mixture and a light touch.

Cleaned a few gross windows doing that.

Gas line antifreeze for any sap or contamination on the surface.

Invisible glass + newspaper

000 Steel wool and invisible glass I use it all the time. Works great for stubborn bugs!
