3M Professional P3 Glass Cleaner, Ammonia Free Glass Liquid Spray for Multi-surface, Mirror, Windows & 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 useI 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

Value for money but don’t know how to use😂

Hard water stains are quickly gone

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.

Product is not working it just waste of money not even remove any stain from glass

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
