Glass PolishPRO 250g Cerium Oxide, High-Grade Glass Polishing Powder, Enhanced Formula, TREO 85%, 3.5 Microns, Brown – GP90008

I purchased a used car with significant wiper scratches on the windscreen. I was advised that the scratches were too deep to polish out and to have a new windscreen fitted, but I decided to give this product a try first. I used the product with a powerful rotary polisher and was amazed to see the majority of the scratches disappear! The polishing process was incredibly slow and although some of the deepest scratches are still there, they are much less visible. I can't say whether it will be as effective for you as it depends on the level of damage to the glass, and I would advise extreme caution as incorrect use of the product with an electric polisher could cause greater damage to the glass. Be prepared to put a few hours in, start on a slower speed and DO NOT allow the glass to dry out as heat from the rotary may cause it to shatter!

Absolutely great Stuff Works brilliant very easy to use simply mix into a slightly thick soup like paste apply to buffing pad to affected areas and while using apply slight water with to screen with spray bottle definite value for money compared to buying new windscreen Fully recommend👍

Quality product. Good value. Rapid dispatch.

It seems like it didn't get rid of the swirls off the windshield, but it got rid of the discoloration and hazy areas. I have mixed it with water in correct ratio, and applied by polisher with 1200-1500 RPMS for almost 3 hours.

Has the job done but on fourth time.

Easy to use & the results are amazing. Tried everything to get water marks off the car windscreen without success & this brought them off in seconds. Used a DA polisher on the windscreen, then shower screens, glass hob etc... highly recommend.

Tried to remove surface scratches from a glass dining table top. Useless!!

I bought this to remove limescale from a shower screen. Nothing else I have tried worked. It DOES work but it is not instantaneous. You have to put in a lot of work with a buffing tool with a flat felt pad and work on a small area at a time. Making the powder into a paste and keeping it warm in a water bath does also help. We were going to replace the shower screen but now it is very presentable, not completely clear so I will probably give it another go… making it the fourth time but it has been worth the effort!! Cheaper than replacement too!!
