3D SiO2 Ceramic Glass Cleaner, GLW Series | Water & Rain Repellent | All-Weather Protective Ceramic Glass Cleaner | Safe for Tinted, Non-Tinted Windows & Mirrors | DIY Car Detailing | 16 oz

This product goes on easily and did not streak when applied as instructed. Wipes off easily and left my windows spotless. Water beads up nicely. I’ve started using this on our shower glass and exterior house windows and it works great for that too.

Strong product, completely removes dirt combined with a good watermark remover

This stuff cleans nicely with out any smudging but it’s not as hydrophobic as I’d hoped. I live in the Seattle area so it’s rain rain rain and the beading on the windshield was disappointing.

I bought this no for the protection (non-existent) that it claims but bc many have talked about its ease of use and streak-free nature. I have to use a 2nd dry waffle weave towel after cleaning to get a good finish. Undrdog "Window Warsh" will continue being my go to glass cleaner.

I don’t think I’ve ever been able to clean my windows and not leave streaks behind that are revealed by oncoming headlights at night. The most difficult part of cleaning windows is cleaning the inside of the windshield. This window cleaner made that task easy. This will remain in my car cleaning arsenal.

The product is working great. Don’t spray too much product it will be hard to spread out. Always remember to shake it or any other product before use.

I've used griots version of water repellent for windshields. That is much more of a pain than this- clean windshield, polish, apply two coats in crisscross pattern. It lasts a couple months after one application. I've driven without wipers on when going 45 and 60+ in pretty heavy rain. The beads were large enough that I could easily see everything.I own several other 3d products and love the company, so I wanted to try out a "ceramic" version of rain repellent. We made a trip from Maryland to Ohio and as luck would have it, we went through several rain storms which put this through its paces. It does cause beads and rolling like griots. The problem is it leaves more residual water behind that obscures your view. There's no way to safely go through a rain storm without using you wipers. That was the case from a light sprinkle to a pretty severe downpour.I followed the application instructions as recommended, so that's not the reason. Maybe I'd apply more next time around, but it does cause a decent haze on the windshield (similar to griots), so you'll need to clear that away to safely see, especially at dark. It works a little bit, but not enough.

This is a very good products. Cleans good it does not leave streak but sometimes smudges easy to remove.
