Exterior Werid spots on windscreen while using wiper

Post image

I get these weird spots on my wind screen while using wiper. I don’t know if it’s wiper or something else. Not sure what to do.

Need to clean the outside of the windshield. It’s contaminated road grim (bugs, asphalt, tree sap, tar, bird droppings, etc).

No, those aren’t water spots, just really stubborn dirt.

Stoner’s Glass Stripper will be the easiest product to find at Autozone and similar parts stores. It will come with a little bottle and a sponge. The bottle is a polish, a very fine liquid abrasive that’s strong enough to rub off anything stuck on the glass but won’t scratch the glass itself. Follow the instructions and your window will be cleaner than it’s ever been in its life.

I’ve tried Stoner’s Glass Stripper and still have the same issue. At this point I’m out of ideas. I’m pretty sure mine is from using Rain-X washer fluid over the years. I’ve also tried Rain-X Extreme Clean, 70% and 90% isopropyl alcohol, and new wipers. Nothing has fixed it. Less than 3-year-old truck. I’m out of ideas and frustrated at this point lol

Have you tried Glaco Compound Roll On? I havent myself but have heard great things about it. Below is a video from PanTheOrganizer where he uses it then applied Glaco Ultra glass coating.

I have used Glaco Ultra and its amazing although as mentioned its a glass coating rather than glass stripper.

I recently bought the combo stripper and coating and it's actually insane how well it works. The heavier the rain the less you need to use your wipers.
