I've been using it for 40 years with no problems.
Must be the newsprint I wipe with.
The newsprint is a good idea. That's all we ever used in the restaurants I worked at. The problem with paper towels is the fact that there is a lot of glue in the paper fibers, which contributes to streaking.
I used Windex for a long time, close to 40 years as well, probably, and I didn't see any problems. Then I got
schooled by a detailer, then did some more research. Using Windex, it's not like the windshield will just fall right out (although aftermarket tint will dry out and peel). But ammonia and alcohol isn't good (especially on paint!) because it dries out rubber and plastic. Windex does have an ammonia-free formula now that's supposed to be pretty good.
Still, auto glass companies, and glass replacement companies like Safelite, car dealers, detailers, they all use glass cleaner made mostly by Sprayway, and Stoners. Mopar Genuine Glass Cleaner? It's Sprayway. Go to any car dealer and buy their expensive can of glass cleaner, and it's rebranded Sprayway. Safelite, same thing. So that's what I use.
But if you're happy with Windex, or vinegar water, or whatever, that's what you should use.
Sprayway makes some awesome stuff.
I usually get my Sprayway fix
here. Wonderful people, great to deal with. They're a Christ-centered business, but I don't hold that against them.
I delivered there once, which is how I know about them. They're in the boonies, a little ways west of Dodge City, Kansas.
