I've been using RainX on both my cars for
about nine monthes. It considerably helps
visibility in the rain and I don't have to use the
windshield wipers a lot.
Does anyone have any home-made recipies to
put on windshields to repel rain like RainX? (I've
read that glycergin works well).
If you have used RainX, what have your
experiences been? How do you apply it, and how


  • Use RainX on a regular basis, about every 6 months I apply it. Works great. At highway speeds even with a steady downpour I don't need to use the wipers. And the wipers make less noise, streak less, when you do use them.

    I apply just like it says on the back of the bottle. Take a rag, pour some Rain-X onto the rag and apply on windows in a circular motion like wax. Once it forms a slight haze wipe off with another dry rag.
  • I'm not a big fan of the RainX products, especially the invisible windshield wiper product. My reason, primarily, is because you have to keep applying it on a regular basis. If you don't, the windshield wipers eventually smear your windshield (which is next to impossible to clean off). For my money, nothing beats a good vinegar, water, lemon solution to clean the windshield combined with a good set of wipers. By the way, since I drive a sedan and don't have a wiper on the back window, I DO use the RainX on it. Rear vision in a rain storm is exemplary.

    After you apply the RainX and let it come to a haze, how long do you wait to wipe it off? I find that when you let the haze sit for 5-10 minutes (longer than the directions, I know), the RainX works better and lasts longer. Just wondering.

    I don't know about lasting longer, but I have found that it's easier to wipe off if I let it sit overnight.
  • dzul,

    I usually let it sit on the window's for about the same time, about 10 minutes. But only in the garage. In the sun you should wipe it off after only 5 minutes or so. It does last longer when you let it sit for 10-15 minutes, that's why I do it too.
  • This morning I tried pulling up the Rain-X home page. Didn't have any luck, ended up with Quaker State Motor Oil. Anyway I did some net serfing and ended up with the BMW page, they (BMW) say stay away from Rain-X.
    Don't get me wrong, I like Rain-X, the only thing I dont like is when you have to use the wipers you get a big smear on the windshield. This can be dangerous at night if your meeting a car head on.
    I like Rain-X on my mirrors helps keep the rain off and you sure can see a lot better.
    I would like to e-mail the people at Rain-X because I have some questions only they can answer, does anyone have their e-mail address?
  • My wipers don't smear the windows with Rain-X applied to them. Are you sure you took all of the Rain-X off of the window??? Maybe you left Rain-X residue on the window.

    I've never had Rain-X smear. I put it on my truck after 120K miles for the first time, and became a true believer. My only complaint is that it doesn't last very long (approx 2 months).

    How long are other people's lasting? Have you tried their Rain-X glass cleaner? It's suppose to make your Rain-X last longer.
  • The repelling power obviously goes away with age but my windows continue to repel some water even after 5 or 6 months.
  • pcheng,

    THe reason your rain-X applications may only be lasting 2 months is because you are putting on a very thin layer. YOu might want to try to apply a thicker layer or apply 2 or 3 layers of rain-X, one after another, every time you apply rain-X..
  • pchengpcheng Posts: 165
    I'll give that a try. Remanants of Floyd is suppose to pass through tomorrow.
  • My windshield wiper moter broke, and because of rain-x I didn't bother to fix it for over a year. (Intermitant peoblem, when I got the truck the wipers didn't work in winter, eventially they went out in summer. I didn't care, with rain-x I never used them anyway.

    Then I got a job in the city, where I had to deal with stop and go traffic. Rain-x is worthless at less then 20 mph, and of questionable worth at less then 45. For the times when it rains and traffic is not bad I like it.

    Just remember that even though you can see better with rain-x in heavy rain then wipers, doesn't mean your can't hydroplane. Keep the speeds reasonable for the condidtions.
  • I have used rain x for about 3 years and I like it real well. When I put it on I let it haze over put on one more coat let sit till cloudy wipe with a dry paper towel then get one wet and go over it real good this keeps it from streaking and it lasts for about 2 months but from my expreance you have to wipe with a wet towel or it will streak and cause all kinds of trouble.
  • I have had no problems with smear using Rain-X , but it is a little work to get it all off when applied. It seems the harder it rains the better it works.
  • i've been using rain-s for several years and i've been applying it straight to the windshield and using paper towels to smooth it around and buff. i don't think that this has any deleterious effect on the product - however, I never wait to take it off and it still lasts me about 2 months on the windshield. for the above post who said it doesn't streak, how do you apply it? the worst is driving in the city with streaking and lots of lights. i'd like to correct that if possible. thanks.

    In addition to hand-appling the Rain-X, buy the
    windshield washer Rain-X Additive.
    The combination seems to provide better protection and hold up much longer.
  • After reading all this great stuff about Rain-x, I put some on the windshield. I wiped and wiped for a long time to get it off and it looked clean from outside the car. When I am inside the car, though, there seems to still be a slight haze on the windshield. If I use the washer fluid and wipers, it smears really badly, but then dries. Is there anything I can do now that will help or do I have to live with it? Is there any way to remove this stuff?

    Try cleaning the windows with windex. That usally works for me. The rain x will still work afterwards too.
  • I tried Rain-x for a year and ended up hating the stuff because of the extreme streaking in city traffic. I stopped using it all together.

    Instead, a friend who drove a Seattle Transit System bus told me that they use ordinary "Cream of Tartar" on their windshields, it's an ordinary kitchen spice - I believe.

    I place the powdery stuff in a shallow soup bowl, add tap water to make a paste and apply to the windshield with a wet sponge in a vigorous circle pattern. Then, rinse off with a garden hose or, with a clear wet sponge until the glass is clear. I mean to tell you that the paste cleans every molecule off of the windshield - almost like a miracle. If you want to really clean a windshield - try it once or twice to see the results.

    hmmm... interesting method....
    how think of a paste do you make?
  • Take big kosher hot dogs and slip them over your wiper blades. Then, turn your defroster on high and wipe away! The dogs and the cream of tartar sauce make a great snack! :)
  • The cream of tarter paste consistency is about the same as a pancake batter mix - maybe a little more body.

    Are the hot dogs beef, pork, pork and beef, deer sausage or Italian sausage?

    With your comment, I take it that you think the process with cream of tarter is a farce?? I say to you --- try it -you'll like it.
  • Rain-X Weenies...hmmm...*munch* *munch* *mun-* *FAINT*

    about the cream of tartar, sounds interesting, you use it on the inside as well, and wipe it off with the sponge? I have a 6 month old car with leather seats, and the off-gassing on the windows is intense, do you know if it gets that off well?
  • So far, I have used the cream of tartar only on the outside glass surfaces. Never occured to me to use inside - though I see no reason why it won't work. Try it, but be careful not to get the mixture on leather or fabric. I seriously doubt that it would hurt anything - but - it would have to be scrubbed off - a pain.

    After using tartar mixture inside, dry the surface and finish the job with Windex and a rag or paper towel. It will really be clean then.

    Some in this chat room poke fun at the process - but, it works well. they probably are insecure??
  • pat455pat455 Posts: 603
    Y'know, washing inside windows is such a pain anyway! (My car has pretty severe slopes in the front and back.) You hadn't mentioned the windex, you do that on the outside to finish up?

    And to get back to the topic, you said you had used RainX - does this cream of tartar method provide similar effects in the rain as RainX does?
  • No, using cream of tartar does NOT provide the same effect as does RainX. The single purpose of using cream of tartar is to CLEAN the window surface.

    Then, if you are a believer in RainX, you can apply RainX to the clean window surface.
    Using this process gives you very clean windows and RainX of course, puts a coating on that lets the rain water run right off - straight away.My objection to RainX is that after a while, the glass surface streaks badly. I will not use RainX again for that reason - even though I have a couple of large bottles that were given to me.

    Finally, yes I use Windex on the outside glass to finish up.

    Gotcha, thanks, I may just try it out some weekend.

    I love Rain-X and similar products like Aqua-pel etc.

    When it rains I hardly have to use my winsdshield wipers. I love the way water just flies of the windshield.

    I have friends who used to use car wax on their window. Surprising this does work, but it just makes the water bead on the glass. It doesn't run of quickly like Rain-X.
  • ccotenjccotenj Posts: 610
    that's because wax is "wax" and rain-x is "polish" (i believe, anyway)... two different things...
