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

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

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.

The best glass cleaner I've used , better than leading other fast glass cleaners,dries fast and cuts dirt and grease amazing

Excellent product,cleans glass superbly no smears

This is top quality 👌 Works really well.

Amazing! Tried so many products and ways to clean my glass properly and this is exactly what I’ve been looking for. Noticed the shine as soon as I started using it, no streaks or residue and it even smells nice

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.
