Fast Glass, Car Window Cleaning Spray, 500ml | Streak-Free Car Glass Cleaner for Windscreens, Windows & Mirrors – Crystal-Clear Finish

You may think that Autoglym products are expensive but cost is always related to quality and when viewed in this way then Autoglym products represent excellent value. Cleaning car windows (exterior and interior) can be a real pain. Fast Glass takes all the pain away from cleaning car windows. It really is fast, effective and leaves the windows absolutely streak free. The fragrance is fresh and pleasant so it can be used on the interior windows of the car. Great product.

Definitely one of the best glass cleaners on the market. Works quickly and well with little effort.

I bought Autoglym Fast Glass after reading several positive reviews, and I must say it has exceeded my expectations. As a driving instructor, keeping the car’s glass spotless is very important to me. The cleaner delivers a streak-free finish, making the windows look crystal clear. It’s quick to use and very effective, which is perfect for clean up before a lesson.

I have found that this is best product for our Motorhome as it is suitable for both glass and acrylic windows, which we have both. Acrylic comes up lovely and easily both inside and out with no smearing and little effort. Glass again comes up well but more effort. Bugs come away easily as well. My go to window spray currently. Four stars as if you have not just washed the van I need to do the windows a couple of times to get them smear free.

I've been really impressed with Autoglym Fast Glass, 500ml—it's truly an easy-to-use product that makes cleaning my car windscreen a breeze. The spray-on, wipe-off formula means there's no fuss; just a quick application with a microfibre cloth and any dirt, dust, or smudges vanish in seconds. It even tackles stubborn road grime, tree sap, and insect remains with hardly any effort required. What stands out most is the gorgeous, crystal-clear finish it leaves behind. After cleaning, my windscreen is streak-free, with superb clarity for an unobstructed view—ideal for safe driving, especially in changeable UK weather. There’s no residue, smearing, or annoying haze left on the glass, just a professional shine every time. The finish is so good, it almost feels like there’s no glass there at all! If you value both simplicity and results, this is a fantastic glass cleaner that consistently delivers spotless, clear viewing through the windscreen, making every drive feel safer and looking smarter.

Expensive, but way better than ordinary window cleaner. Removes road mess with virtually no streaking. Recommended.

Amazing product just works the class looks better than when new.

Bought this before and was very pleased with it. Does a great job on the windscreen and headlights

Excellent produit

This is the best window cleaner that I have ever used.very little streaking if any. Use micro fibre towels. And polish the window with a clean micro fibre towels Canadian Tire used to sell it but for some reason they quit selling it.
