3M Professional P3 Glass Cleaner, Ammonia Free Liquid Spray for Multi-surface, Mirror, Windows and Commercial Use, Just Spray & Wipe, Remove Tough Stains with Streak-free Shine (5L, Pack of 1)

This is a concentrated liquid so it need to be mixed water hence can be used for longe period if for personal use I got it primarily to clean car glass and it does the job perfectly I use it to clean when glass is stained and not as windscreen wiper fluid though I think this would work great for that also

Good

It's basically commercial Colin much beer than the Colin we find in the market, last long and cleans much better and you need to dilute is with water ,must buy .

This is just strong enough to take way the traffic films on the glass. Do follow the instructions and dilute the product accordingly. I use isopropyl alcohol for the dilution as that work very good for me on my cars window, wide shield cleaning. After use do thoroughly rinse the paint work as if there is a coating it may affect. This has Butyl glycol in good measure so does the job appreciably well. I did try with di ionized water but the strength got reduced. Personally it is cost effective and does the job well for the purpose of Auto Detailing and Glass Cleaning. Cheers B Visual - Auto Detailing Consultant

gud product

It takes time to get ride of the water mark and after a few days they are back but the sent is really nice it is good value for money

Excellent glass cleaner. Removes stubborn stains when used as concentrate. In every other case it is very effective when used with good microfiber cloths. I use this to clean my home windows as well as car windshield. This is relatively streak free.
