We also tested it’s dust repellencey and we’re pleased to say that it does help to minimise dust build up on the glass work. Gtechniq do recommend that you use their own dedicated microfibre towels, and we would agree with this approach. On both forms of glass, it left a flawless finish. We also tried it on glass that had and hadn’t been treated with G1 to see if there would be any difference in terms of cleaning ability.

Unlike cheaper glass cleaners, this didn’t leave any streaks during our tests which is a pleasant surprise. It’s really easy to use, just a spray on and buff off application. G6 and G1 were developed at the same time to ensure that they complement each other well. G6 Perfect Glass is the perfect companion for glass that has been treated with Gtechniq G1.

However, you still need to keep on top of this and ensure that the dirt is kept at bay. We’ve previously covered Gtechniqs G1 glass coating which creates a water repellent barrier on the glass as well as repelling dirt.

By the time I’ve washed the rest of the car, I then apply one more squirt of Fast Glass to the glass and buff over with a microfibre cloth. In the winter months where there is a lot of grime stuck to the windows, I like to pre-treat the window first by applying a few extra squirts onto the window, before rinsing it off with the hose. That is nothing short of exceptional, and for that reason, it’s our number one pick on this list. I’m able to clean all of the exterior glass on the car in under five minutes. Two sprays is more than enough to clean the windscreen on my Clio, so it’ll last a long time.

A little goes a long way when it comes to Fast Glass. Fast Glass removes these with ease and doesn’t require any heavy buffing or reapplication.Īs an added bonus, this can also be used on infotainment screens of various types in your car in order to clean them. One of the hardest things to remove from glass is sticky hand prints. However, it should be noted that Autoglym recommend that you do not do this. I’ve personally used this with the sun beating down on it, and it was still easy to buff off of the glass and leave it looking so clean that you’d think the glass wasn’t there. Fast Glass has consistently beaten the competition with respect to its price and also its cleaning power. We’ve been a fan of Fast Glass from Autoglym for a long time, and you can read our full review of it here.
