GLASS POLISH PRO Cerium Oxide Glass Polishing Powder – 50g High-Grade 85% Pure Suspension-Treated Formula, 3.5 Micron for Glass Scratch Removal, Windscreen Polishing and Restoration

Worked really well, removed several heavy scratches from a a car windscreen.

This stuff is the professional glass polish, but you have to follow the instructions (mix it up moderately thick is the best way) and be prepared to sit polishing for two hours. It took some nasty scratches out of my Casio watch glass so certainly works. Probably best to use a leather polishing wheel in a rotary tool and protect surrounding surfaces because the dust goes a long way.

I took a punt on this stuff with low expectations as I've no power tools to apply it with and a lot of people were saying they were required to get any results, but a few people were claiming success with applying it by hand and I'm writing this review to confirm it does work on very light scratches even on tempered glass, although it's hard work. I bought a car which had an area a few inches square on the driver's side window with dozens of fine scratches going all directions. A few could be felt with a fingernail, most couldn't. They were a distraction when looking to that side, especially if the sun was hitting them, as they were just above the part of the window you look through to see in the side mirror, and I was considering getting the window replaced so I figured it was worth trying the DIY option first. I've attached a photo showing before and after probably an hour or so in total of vigorous scrubbing with the paste I made up, which I applied using a combination of microfibre cloth, and a rayon glass polishing pad attached to a velcro backing pad with hand strap (both found on Amazon.) As you can see most of the really fine hairline scratches are no longer visible even with direct sunlight hitting the window, and many of the deeper ones are noticeably lighter. At the angle I'm viewing the window from during normal driving they're even less visible than in the pic, and getting rid of the overall haze of fine lines has stopped the remaining scratches catching my eye, so well worth the effort. I actually had trouble getting the camera to see the scratches for the "after" pic, had to keep my finger near them for it to focus on as otherwise they weren't showing up at all, whereas before it was auto-focusing on them every time. For the price I'd say it's worth a go using this stuff by hand - even if it doesn't remove the scratches you should be able to get a noticeable improvement in the overall appearance.

Very hard work Took me 5 hours I had three long scratches ..it make a message off everything I mean everything get covered up even your drill cover it this stuff gets inside your drill I bought two pots of this stuff and 4 pads with adapter for the drill cost £31.00...

FOR LING SCRATCHES I WOULD NIT USE THIS PRODUCT AGAIN .IT TO MUCH HARD WORK AND VERY VERY MESSY ..

I bought this because of the excellent review from Andy H (see other review). I had a light scratch in my windscreen caused by a little bit of grit being caught under the ice-scraper (like him). It was too small to feel with a fingernail, but it 'lit up' when driving into the sunshine. The worst thing was that it was directly at my eye height so was very distracting and even 'lit up' at night when car headlights caught it. Very annoying. I tried a few things to remove it, including Brasso that someone suggested. The mark was less 'harsh' but not removed. I was pricing up replacement windscreens and had nothing to loose, so I tried this. I removed some of the powder into a separate glass jar and added drops of water using a teaspoon, mixing until it was a consistency of ketchup. I didn't use a drill or polisher machine. Just a clean microfibre cloth and some elbow grease. Used tape on the inside of the windscreen to stay on the scratch and polished by hand. After the first 5 mins I could see a distinct improvement in the scratch. A few more goes and it was gone. It takes time, but you need to keep going and checking that the defect is removed. Tested in full sunlight and at night too and the screen looks great now. Very happy with the result. This is a very fine polishing compound, not a miracle cure you wipe on and wipe off. I suspect that those who are disappointed ion the results are not using the right amount or elbow grease or method. But, now I have a 'glass polish' I can use the remove defects. light scratches and windscreen wiper marks from glass without worrying about damaging stuff. You just need to take your time and it works well...

Sorry it didn’t work for me I used to work in a car body shop for over 10 years and we couldn’t get scratches off the windshield but I thought I’d give this ago but didn’t work and didn’t think the marks was to bad I even tried my work shop buffer but still no joy Maybe to deep

Windscreen on my daughter's car had very bad scratches where it looked like the wipers had been switched on with no blades attached. 2 big arc shaped scratches Used this along with a DA (dual action) polisher and a 3" glass polishing pad. Spent 40 mins and the scratches are 90% gone. Only the very deep bits remain but they are far less noticeable now.

still testing tried small spot seams ok but stil testing

Perfect

Werkt goed om welo opaal te polijsten, een nadeel is dat de deksel niet goed gesloten was bij aankomst hierdoor vliegt een hoop poeder eruit bij de eerste keer openen vandaar raad ik iedereen aan dit buiten te doen je wilt dit namelijk echt niet inademen! , verse prima voor opaal & glas

Marche très bien pour retirer les rayure superficiel sur les vitrocéramique, c’est légèrement éclaboussant mais facile à nettoyer

Usado 1 unica vez, y con resultados satisfactorios. Usare una 2° con un poco mas de seguridad y fuerza pero de primeras, contento con el producto

Use foam disk from head light restoration kit and polished my stove top. It was badly scratched took about an hour but looks great.
