Did Rain-x ruin my windshield or is it normal (how to make it better)?

From: Slacker on 6 Oct 2007 13:45 My windshield is fine except in the morning when the dew and sunshine combine to make it impossible to see due to this naughty spotty on/off film that I just can't windshield wipe off. Even the mirrors are spotty in the morning. The rear and side windows are fine. When I was driving the neighbor's fifteen year old to school yesterday morning, he said it was the nasty rainx. What rainx? I bought the car used about six months ago and I never used anything with rain x on the windshield. Is rain-x the culprit? If so, how do I save the windshield? Is there a way to remove this rain x stuff so I can see again?
From: hls on 6 Oct 2007 14:52 I used RainX once and didnt really care for it. It is, I believe, a silicone compound that adsorbs upon your windshield glass and makes it shed water quickly. As mine deteriorated, I had some issues with patchy spots, and decided if I ever got it clean I would never use the stuff again. You spots may be from oil from the engine or highway, dirty wipers, paint or chemicals which have drifted onto your car or maybe even more possibilities. You may have to clean the glass with a good glass cleaner and replace your wiper blades to get relief. (I have some windows that are so badly filmed with "something" I have never been able to get them clean.)
From: Steve Kraus on 6 Oct 2007 15:35 You might even want to wipe your windshield down with a solvent like paint thinner (don't get it on anything else!) to remove any sort of films ordinary cleaning won't and then wash it thoroughly with detergent to make sure that in turn is removed.

I tried the inside anti- fog stuff and didn't like it at all (smeary). I do not believe it has ANY silicone in it...it is more like a solvent. It allows you to see while driving in the rain without wipers...that is a great safety factor. (I own no interest or stocks in this product) ; )

At any rate, I dont like it for my windshield. Quaternary amines have long been used inside the windows to break the surface tension and allow droplets to flow together in a clear film rather than a fog. The composition cited earlier looks like an ester quat. Just from the formulation, I would not have suspected it would be persistent enough to last on the exterior of a windshield. Live and learn. I have thought about trying it in my bathroom on the shower tiles. Maybe it would help them shed water, etc. |
