What are the steps for windshield polishing?

Glass surface cleaning and preparation before glass polishing. Use P120#, P240#, P400#, P600# glass sandpaper to remove glass scratches. Switch to polishing solution and use a dedicated polishing wheel to restore glass clarity.
I recently polished my car's windshield myself and the results were quite satisfying. The first step was to thoroughly clean the glass surface using soapy water or a professional cleaner to remove grease and dust, ensuring no water spots remained. Then, I chose a reliable glass polishing compound and evenly applied it to the polishing pad. I used a cordless drill with a foam pad set to medium speed. During the process, I gently rubbed in circular motions with consistent pressure, avoiding staying in one spot too long to prevent the glass from overheating and cracking. After polishing a small section, I stopped to check if the scratches had diminished. Once done, I rinsed off any residue and applied a protective coating to enhance water repellency. The entire process took about half an hour, and remember to wear gloves and safety goggles for protection. After polishing, visibility improved significantly, especially during rainy nights when water droplets no longer lingered, making driving safer. For deep scratches, I recommend testing on the edges first to avoid damaging the entire windshield. Regular maintenance like this can save you from costly repairs, making it a worthwhile investment.
When polishing the windshield, I prefer to start with cleaning, meticulously wiping it down with a microfiber cloth. Apply a professional polishing compound evenly, using an electric tool like a variable-speed drill set to medium-low speed, moving horizontally instead of in circles to minimize heat stress. Pause every two minutes during the process to check progress and ensure the temperature doesn’t get too high. After completion, clean off any residue and test for clarity, performing the entire process indoors to avoid direct sunlight. These small tricks help quickly remove minor scratches and enhance nighttime driving safety. Regular DIY maintenance can also prevent major issues—I recommend using high-quality products combined with manual practice. Beginners should practice on older car glass first to gain experience before working on their primary vehicle.
