Meguiar's Perfect Clarity Glass Cleaner - Keep Windows, Windscreens, and Mirrors Gleaming with a Premium Anti-Hazing Formula that Leaves a Superior Streak-Free Finish

This glass sealant really does what it claims. After applying Meguiar’s Perfect Clarity Glass Sealant, rain now beads and slides straight off my windscreen, making driving in bad weather much clearer and safer. It’s easy to apply — just clean the glass, apply evenly, and buff off. The results are noticeable right away, especially at higher speeds where you barely need to use the wipers. The bottle may look small at 118ml, but a little goes a long way. Excellent quality product from Meguiar’s and well worth the money. I’ll definitely be buying again when it runs out.

Recommended for use by a professional car detailer. Smallish bottle but the product goes a long way. For use as final clean on windscreen. Works.

Does what it says on the bottle... Easy to apply, it's a spray bottle with decent misting and even application. So long as you follow the wiping instructions, one side cloth for spread, the other side to clear it, then you're in for great results. I applied it with one cloth, then wiped it off with another cloth. Cleared the saliva marks from the instruments and interior windows easy-peasy and no streaks. Haven't used it on the exterior, so no clue about longevity or protection to the UK Summer.

Cleans car windows without smearing with minimal buffing. Much better thsn household glass cleaner.

I have used a lot of different glass cleaner in my time but this is by far the best I have now purchased another bottle for inside my house

Have used many glass cleaners for the car. All we're OK until it came to the interior windscreen, no matter how well I cleaned it there was always marks left so I decided to try this, cleaned the inside perfectly, no marks left and so easy to use so I did the outside screen as I had problems with wiper squeak and judder, first time out in the rain wipers left the screen smear free plus no squeaks or judders. Can't recommend this product enough I have purchased a spare bottle while on offer from Amazon.

Very good product easy to use cleans for a good shine

This works well as a glass cleaner both for inside and outside the windscreen. However it also mentions it has an anti-fogging effect. This is not the case and I'm having to use the Aircon just as much to deal with that as before. Rain-X also offer an anti-fogging glass cleaner so I am going to try that next.
