Glass Polish 1.76oz (50g) Cerium Oxide High Grade Glass Polishing Powder - TREO 85% - 3.5 microns - GP90006

They said it couldn’t be done but it can. By using cerium oxide with a little water to make a paste, I was able to use a Dremel tool with buffing wheel to polish scratches out of a wrist watch's mineral crystal. It does take a little time and patience and works well with light scratches. I did have deep scars on one crystal but by the time the scars were polished out the crystal has a slight ripple. It is only noticeable to the wearer but the watch is absolutely readable

The reviews on this product not working for glass scratches and pitting have no clue what this product is actually for. This is a polishing compound, not a cutting compound. It will not sand off layers of glass to smooth out scratches or pits.I had a film all over a new window glass for my back door that no cleaner could remove. Mixed this up and followed the instructions with a vehicle rotary polisher and now the glass looks good as new.

I recently purchased a car with around 90K miles and the windshield has seen better days. As an experiment I decided to polish about 1/3 of my windshield just to see if this is a worthwhile effort and the answer is partially. It did seem to remove the light swirls caused from dirty wipers but didn't do anything for the pits created from rocks and other debris. Overall i do see an improvement and honestly didn't expect it to look like new. Was it worth it? I really need to drive it at dusk for a better perspective but given the mild improvement seen so far i would say yes.Update: After a few attempts it definitely removed the scratches created by the wipers. Definitely a significant improvement overall as visibility is much better. Unfortunately I don’t believe it did anything for the small stone pits.

Had a very superficially scratched bathroom mirror, we used this but it didn’t make a difference for it.

I used this glass polish to try and remove some light scratches on a watch crystal. The scratches are very light but visible enough that they bother me. I already tried other methods to try and remove the scratches: baking soda and toothpaste, which did absolutely nothing.Does this powder work? Sort of. I used a dremel rotary tool at 15,000 rpm with a felt attachment. I worked on the scratches for a total of about 40-45 minutes, stopping every few minutes to rinse the watch and check for improvements. The scratches are marginally better, where they are now slightly less noticeable, but they're still there. I don't think they'll ever be completely gone. The reason for my low rating? (1) The product is very overpriced for a mere 50 grams of powder; (2) it's extremely messy and not user-friendly (plan on covering your work surface completely and having to spend a long time cleaning up everything, including yourself, once you're done); (3) the product ultimately doesn't deliver on its claims; (4) it takes way too long to get results that you can barely call an improvement at all and, ultimately, the scratches are still there.Is it worth it? It wasn't for me, but it really depends on what type of scratches you need to remove and how much time and work you're willing to put into doing this. I'll keep looking for something that's more effective and not as messy.

We had a semi-circular, 1 inch scratch on the windshield due to a defective wiper blade.I tried toothpaste, chrome polish, rubbing compound, several commercial products claiming to remove scratches on glass. Nothing worked.I found this product and decided to give it a try.I added a small amount of water to the compound, then applied it with a wool polishing brush on my drill. I made one pass over the scratched area, then a couple more. The scratches were noticeably better. I repeated the process several times over three days before the scratches were completely gone.I was ready to give up and buy a new windshield until I found this product. The windshield is perfectly clear now. It took some work, but it was well worth it.

Raye mi cámara de acción insta 360, los vídeos se veían mal con el reflejo de luz. Busque por internet como eliminar las rayas y me encontré con este producto, estaba desesperado ya que uso mucho mi cámara, lo compré y lo usé.Tape la cámara con cinta para no hacerle más rayas, dejando al descubierto solo la parte a pulir.Agregué un poco en un envase pequeño le coloqué un poquito de agua haciendo una pasta líquida, no mucha agua no mucho óxido, revolví y moje un isopo y empecé a pulir con un paño de microfibra, mojaba de nuevo colocaba al lente y pulía, el pululado fue hecho a mano, eso si dure aproximadamente una hora y media. Y me impresionó el resultado, quedaron unas rayas mínimas, pero creo que son muy profundas. Estoy muy contento con el resultado. Me ahorro que la cámara viaje a china para garantía…
