Hey all hope it's okay to post this but I have been trying to get rid of this streak with no outcome. Tried to clay it , IPA wipe down , and clay towel can't get anything to work. Would anyone have a recommendation. Don't have a DA

Also this area always causes my windshield wipers to chatter on this exact spot and it feels ruff going over it even though it looks clean and clear

90% alcohol or Denatured alcohol should work -- just try not to get it on the paint.

I've used 50% distilled white vinegar and 50% water for streaks. That's a peculiar looking streak. Hope you get it out.

That looks like overspray from ceramic or some chemical? Unfortunately, since you have tried the recommended treatments, the only way to remove this stubborn stain is to one-step with DA. I would ipa wipe down, one step has worked or even better Carpro Ceri Glass with a rayon pad. I would put a sealant of some sort to protect the glass, even rainx works wonders. Good luck.
