This type of product would be available at any auto parts and supply store – it’s used to remove grease and wax to prep a car for paint. Since RainX is silicone based, a grease, wax and tar remover should work and that would take off and bugs and other road grime as well. I have found the best way to remove RainX from your windshield at home is actually with soft scrub and a paper towel which won’t damage the car or glass. Then if the film has worn off the windshield in the wiper area and dried out the wipers, the hardened wipers themselves could cause permanent damge to the windshield. The film left behind can affect the clarity of the windshield, as well as build up on the wipers and moldings, especially if you also use the RainX wiper fluid.Īside from leaving a white or orange crust another downside of this RainX film that develops is that it robs the moldings and wipers of their ability to retain their own moisture and stay soft. But eventually it wears down and degrades. RainX and similar products are silicone based materials that make a filmy layer on the windshield causing the water to roll off, similar to the effect of rinsing greasy hands. But they work in completely different ways, with different types of chemicals. There has been lots of comparison between RainX and Aquapel, because they are both made to serve the same purpose – windshield rain repellents.
