Optical Grade Cerium Oxide 8oz Glass Repair Powder | Glass Window and Windshield Repair

SUMMARY:Makes a mess and takes a bit of time, but WORKS VERY WELL to remove light scratches and hard water stains on glass.EXPLANATION:My Tenants never cleaned and never put salt in the water softener. This left me with horrible hard water stains on my glass shower doors. I tried every cleaning product I own in an attempt to remove the stains. I even tried 5000 grit sand paper (which worked, but took a LONG time and left light scratches). A friend recommended a slightly abrasive cleaner (I won't mention the name), which removed the hard water stains, but left VERY visible, but light, scratches on the glass (fortunately, I only used it on a 1ft square area).At this point, my focus was to get rid of the scratches, which looked much worse than the hard water spots. After some research, I found some videos showing people removing scratches using Cerium Oxide. I decided to give it a try since, at this point, I pretty-much ruined my shower doors.Using a cordless drill and a 3" diameter Felt pad attachment, I worked on the scratched area for about 30 minutes. It made a big mess, but IT WORKED, the scratches are GONE! Now that the worst problem was solved, I moved onto the hard water stains. It worked perfectly, in fact it's much easier (takes less time) to buff out the hard water stains. Cleaning up the mess actually takes longer than buffing out the stains.Overall I'm extremely pleased. I had almost given up on fixing my shower doors. If it hadn't been for the scratches left by the previous cleaner, I never would have searched for (and found) Cerium Oxide.In an attempt to show you what it does on the hard water stains, I took a series of photos (attached). Notice the hard water stains below the word "BEFORE". It took less than 5 minutes to buff them out. It's difficult to get good pictures (I had to work quickly, while the sun was hitting that particular area), but I hope you can see that it looks much better now.I wish I had found Cerium Oxide months ago, it would have avoided a lot of frustration and wasted time. I hope you find similar success.

Got this because I used a green scrub sponge on my new hurricane sliding doors, like an idiot 🤦🏼‍♀️. Granted I just used it on a small area but still left some scratch marks. Got this, after looking at reviews and other products. I tried the baking soda and toothpaste method to no avail, but this worked pretty good. I was afraid to use a machine buffer on my new doors so I did it by hand, with the provided buffer sponge. Well after lots of scrubbing and sweating and elbow grease, the scratches are gone!! Needless to say, this product worked perfectly and I have plenty left, just in case I be an idiot again and grab the wrong sponge to clean the sliding doors.

Follow the instructions to the T with no results. All scratches were still very visible on the table. Don't waste your time or money.

In all technicality the product worked. It buffed out my scratches.... andddd my oleophobic coating along with it on my phone screen. now I have a big spot where my phone smudges and looks smeared at certain angles. It is fixable so it's not a big deal and that was also my fault for not researching. SO the product does work, it will buff scratches off glass but do be careful on what you're putting it on. Rating 3 stars because ease of use was a little tough and also doesn't have the warning of what you're buffing on packaging or purchase page

The powder dis a great job of removing some wiper blade scratches.. but the included felt bobbing wheel didn't last 5 minutes before the metal shaft just started spinning inside the felt.However, using this powder with a rupes polisher worked very very well.

Great buff included !

I got very smooth results with this. Although polishing took VERY long. I am a newbie, so I had to do a bunch of trial and error and may not have used it properly. I used it for our shower doors. I was struggling with getting too much dust despite wetting it. So I ended up with lots of cleaning to do after the polishing. Thankfully I was using a professional respirator.

made a huge mess, and didn't do anything to the scratches after 30-45 minutes of running the drill attachment

Product doesn’t work did nothing to the scratch
