Whilst this technically isn’t a glass cleaner, Rain-X Anti Fog does serve an important function during the colder months.Apply with a dry cloth and wipe the Rain-X Rain Repellent in a circular, overlapping motion; once you’ve allowed the product to dry, re-apply again and, once the final coat is dry, remove the final layer with a dry cloth or a sprinkling of water.

I folded up a microfibre cloth several times and applied a small amount of Anti Fog to it, before buffing it into the glass in overlapping circles and then allowed it to dry. Unfortunately, the instructions don’t indicate how much product you need to use. As is always the case with detailing, less is more. a>

For the small amount of fogging on the drivers window, re-directing the fans in the car to the driver facing heater got rid of this in a few seconds. There was no need to wipe away the steam on the window. On the passenger side window, there was no steam build up at all. This was after a 40 minute drive when I had to re-direct the fans to remove the small build up on the passengers side. Durability
