Up until recently the only window product I've used is Stoner's Invisible Glass. I don't think it's the source of my problem since I've never had a problem with it in the past. I bought a new can of the spray after to keep in the new truck, so I have no idea if the Stoner's product has changed or if it's just a coincidence.
I've posted some pictures below. These windows are on a new Tacoma with less than 1500 miles on it.
I tried switching to Windex Auto to see if it would cut whatever it is that's on them and it made no difference.
It was recommended that I try using vinegar and it also made no difference.
I've included some photos. The residue you see is on the outside of the window. These windows are freshly cleaned. They feel gritty to the touch.
This last photo is after I wiped down the inside of the windows. There's an oily film on the inside that streaks horribly and makes it near impossible to see if the windows fog. The streaks you see are in a different pattern from how I wiped the window. I haven't been able to remove this film. I'm not sure if it's related to the problems on the outside of the window.
