Did Rain-X make my windshield fog up?

**Springthing** · 06-20-2009, 10:23 PM

I'd squirted the windshield with Rain-X recently, the spray on and wipe type. Well, it worked fine, as it should when we hit some rain. Water beaded up and all.

On the way home, it was 2am and we hit a patch of humid air on one of our country roads. Those that have hit those will know exactly what I mean - your windshield starts to fog up on the outside something bad all of a sudden. It's like fog sticking.

Well, I tried the defroster, I tried doing the windows down, and with the wipers on it was all I could do to keep up with the fogginess. After meeting another car head-on it was actually difficult to see out the front window.

I pulled over and grabbed some napkins we had and 'cleaned' both sides and was able to keep it clear for the rest of the way home.

What are the chances this is due to the Rain-X? Has this ever happened to anyone else? If so, do you recall if you've ever used a windshield product like Rain-X?

Now that I look at the glass in the light it's all smeared with where I wiped it up with the napkins.

What's the best way to clean the glass inside and out? I picked up a spray bottle of automotive windex that I'm going to take to all the windows soon - wanted to check with everyone here first.

Thanks!

use some window cleaner and some good shop towels. I always use rain-x and I've never had any adverse effects. Might just have been a freak accident...

are you sure that the fog was on the outsite? 99% of the time I get a fogged windshield it's on the inside bacause the cab is colder that outside. Otherwise, when it sticks, I wipe this windoshield and the wipers only smear it around.

Please excuse my bad typing this evening, my fingers aren't working with me tonigt I'm so tired.

Positive that it's the outside. Like I said I wiped it up with some napkins as much as I could. The wipers just kind of stopped working in cleaning it up and when a car came in the other direction I was practically blind.

i use rain x all the time personal and work truck. it's great cause u can drive 75 in the rain without using your wipers. you may have not buffed it off completely when you applied it. i usually apply the wipe on wipe off wax type, then for my washer fluid use the rain x brand washer fluid. sometimes if you leave a tiny streak water will stop on it.

I'll try to do the applying and then 'removing'... maybe that was the problem - too much rain-x goop on the windshield.

x2 on the application, I've found that you should buff the rain-x quite firmly for the best results.

I'm not quite sure, to tell you the truth. I'll have to clean the windshield well, reapply the rain-x and see what happens in the future.

Rain-X is a bad deal out here in ND when it's not summer. As soon as the temp changes people get all kinds of bad fog ups where they put the rain-x. I forget what a lot of people use around here but most everybody one base here stopped using rain-x because of the problems they had with it in the winter. Probably the same time of issue with the temp/humidity change in the fog. I'm glad to hear that it turned out ok though and that you all are safe.
