Keep your shower, windows and glass doors shining and clean with this incredible Rain-X Rain Repellent product. On the side windows, there were a few small areas on the drivers side that did start to steam up, although it took quite a long time for this to happen. I’m chalking this up to there not being enough of the Anti Fog on the microfibre cloth. For that reason, I would recommend going over with a second layer to ensure that there is even coverage.

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. DurabilityYou can also use Rain-X on Shower Doors, or on any glass doors or windows in your home, for more amazing water-beading magic! 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.

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.The same process was then used on the other windows in the car, as well as the rear view mirror. On the passenger window, I applied two layers of Anti Fog since this will increase the longevity of it. Results I’m always a bit dubious about the claims some products make. One thing that stood out with Anti Fog though is that it doesn’t claim to completely eradicate any steaming up of the windows. For the windscreen, I purposely only treated sections of it as a comparison to the non treated sections, and it worked exceptionally well. In tests conducted by an American University, better visibility improved drivers’ responses up to a full second or more - helping drivers make better decisions on the road. Therefore, it’s imperative for drivers to improve their visibility on the roads - and there’s no better way of doing so than with Rain-X Rain Repellent.
