Carpro Ceriglass Glass Polish is a product I highly recommend everyone have in their detailing toolbag. Whether applying by hand or machine, it has provided more efficient and overall better results deep cleaning and removing mild defects from glass surfaces.
This bird dropping had etched this glass. This is a picture of what remained on the glass after washing and using detailing clay to clean and remove grime.
I made a circle with the product on a Carpro Gloss pad. At a speed of 3 on a Rupes Duetto I worked the product with 4 to 6 section passes to achieve my desired results. I used distilled water and microfiber towel to remove the majority of the polish residue. With a separate microfiber towel I performed a secondary wipe using Gyeon Prep.
Polishing the entire back window, I divided the area into four parts.
This product has been beneficial to me in removing a variety of chemical stains on glass as well. I have been able to accomplish this even without a machine (rubbing product in by hand with a foam pad). For aggressive polishing, where severe water spotting or even some mild scratches are an issue Carpro Rayon Glass pads paired with Ceriglass make a great combination.
Important reminder: If polishing at a speed higher than 3 on any polisher or using Rayon Glass pads expect this product to dust (powder residue) and leave a mess. Taping certain areas may be of importance before using this product in this case.
