G4 Nanotech Glass Polish

G4 is formulated with nano abrasives and citric acid, giving it the ability to remove hard water spots, road film, and mineral deposits that standard glass cleaner leaves behind. It's a polish, not just a cleaner, which means it actually restores your glass surface rather than just wiping away loose dirt.

G4 is a cleaning solution designed for automotive glass, we do not recommend use on home windows.

Apply G4 with a hand polish pad and work in circular motions until the product breaks down. Use a damp clean microfiber towel to remove residue, then finish with G6 Perfect Glass. Avoid paper towels and stay out of direct sunlight during application.

G4 is safe for factory-tinted glass. However, we don't recommend using it on aftermarket window film or coated glass surfaces. When in doubt, test on a small area first.

For optimal results, use G4 Nanotech Glass Polish whenever you notice buildup on your car's glass surfaces, such as water spots or road grime. Regular use will maintain the clarity and cleanliness of your windows, ensuring a crystal-clear view every time you drive.

G4's mild abrasives can address light surface marks and medium scratches caused by wiper wear or debris. For deep scratches that catch your fingernail, you'll likely need professional glass polishing or replacement.

No. G4 is specifically engineered to remove contaminants without scratching. The nano abrasives are fine enough to polish away water spots and road film while keeping your glass surface smooth and clear.

After polishing, apply G1 ClearVision Smart Glass or G5 Water Repellent Coating for lasting protection. G4 fits naturally into your prep work alongside paint correction and ceramic coating application, while clean glass completes the look of a properly protected vehicle.
