I’m looking forward for using this product for a scratched tempered glass but I’m also worried it will leave it worse than it is now.

Works for its intended purpose. Cerium oxide will remove minor surface scratches from glass. Must use felt polishing pad with some kind of rotary tool or polisher. Expecting it to remove very deep scratches or chips form glass is unrealistic. Any scratch or chip that deep would require insanely long hours of buffing and result in a large depression and possible dangerous weakening of glass. I used mine on a fish tank. Removed three 2.5 inch long scratches in 45 minutes. Used dremmel with felt polishing wheel. Mixed 1 part cerium oxide with 2 parts water. Don't allow to dry while using and keep moving to prevent over heating working area. Also it does tend to splatter. Depending on where you are working, may want to use drop cloths. Cleans up fairly easily nonetheless. Didn't stain cotton tee I got it on and wiped of wall with just water. Google search videos (remove scratches from aquarium glass) for instructional videos on using with glass.

It works great, but using it with a drill attachment will fling this stuff all over the place.The solution is to make a shroud that encloses the drill attachment. Take an empty plastic peanut butter jar (or something similar that is wider than your buffing pad), and drill a hole in the bottom that is a little wider than the shank of the drill attachment. Stick the shank through the hole so that the buffing pad is inside the jar, then carefully cut the jar so that it touches the glass and encloses the pad when you apply normal pressure.Also, use lots of water and go slow. Pay attention to the temperature because this generates a lot of friction heat and can easily crack the glass if you go too fast.

I had bad scratches on my windshield from a faulty ice scraper. I used this cerium oxide with a power buffer and the results are amazing. It won’t get rid of deep scratches you can feel with your fingernail tho. It takes a lot of time and work but after many hours I saved myself hundreds by doing it myself. Be prepared for a lot of elbow grease work!! Would Definately use again. Would be great if u could buy already premixed and just shake.

After a typhoon rolled through my area, my car was left with multiple fine scratches across the windshield from some roofing shingles that hit it. They were right in my line of sight, but rather than replace the windshield, I thought I'd try to buff them out. So I purchased this product and mixed a paste with a little water. It doesn't take much! I used a Porter-Cable DA buffer and Griots Garage glass polishing pads, also purchased on Amazon. It was my first time using all of these products and the process was very easy. Medium to high speed on the buffer and frequent squirts of water with a spray bottle. Took about a hour of slow and steady buffing, but windshield looks great. No haze or swirl marks from the polish. I can still faintly see the scratches in the sunlight, but I suspect a little more time with the buffer would eventually work the, out. At this point, I'm satisfied. Sure cleaned the glass well too.

I mixed the slurry as instructed with water > 80 degrees. Used a felt pad for my drill also bought on here. Worked on the scratch for several hours. Absolutely did nothing for scratch except my cooktop now has a cloudy spot at one end of the scratch, but scratch is not affected at all. Waste of money. Felt pad got so hot it started to turn brown. Cooktop got extremely hot as well, but scratch still remained.

With some elbow grease, this works. You will need a foam bit and drill. I had hard water spots on my very old windows and used an abrasive shower cleaner with drill sponge head to scrub the spots off. This was a big mistake on my part and it left scratches all over my window. I taped the window so I could work in sections and as you can see from the pictures, this stuff was able to buff out the scratches in my glass. The section I've done so far took about 45 minutes, so be prepared to put in time, but its better than permanently dirty windows or replacing the glass.
