You could try cleaning it with 0000 steel wool and aerosol window
cleaner (I prefer Stoner's Invisible Glass) that is my regimen for hard
to clean windows. If it is still spotty you might want to follow up
with some kind of polish.
replace "roosters" with "cox" to reply.
To find what is inside Rain-X, I first tried calling Sopus Products in
Houston at 800-416-1600 but they are only open 8am to 5pm Central time.
Their web page says Rain-X is composed of methanol
Looking deeper, I then tried calling Kafko International, Ltd. 800-528-0334
Interestingly, they say Rain-X is isopropanol and sulfuric acid!
I look again at Shell Oil's Rain-X only to find it's made out of
"unspecified surfactants" and water!
Back at Pennzoil-Quaker State, we find Rain-X composed of clay, alcohol,
Clays = 1-10%
Ethanol/SD Alcohol 40 = 70-95%
Isopropanol = 1-10%
Thickening agent(s) = 1-5%
Moving to Scottsdale Arizona, calling Unelko Corp at 800-528-3149, I find
it's got a whole recipe of "anes", "ols", "acids", and "ones"...
Ethanol/SD Alcohol 40 = 86%
Isopropanol = 4%
Ethyl sulfate = 1%
Polydimethylsiloxanes Silicon oil = <9%
Silicic acid (H4SiO4), tetraethyl ester, hydrolysis products with
chlorotrimethylsilane = <9%
Siloxanes and Silicones, di-Me, hydroxy-terminated = <9%
What's with the ingredients of Rain-X?
Is it basically snake oil and placebo or does it actually have a consistent
It's proprietary formula so not surprising to not find precise
formulation. I posted the constituents from the MSDS earlier in the
thread. It's a water/methanol carrier w/ a small amount of another
organic as the water shedding agent...
In general, to find out stuff like this about proprietary formulations,
look for the MSDS -- it's required to list ingredients and general range
of amounts although not exact formulation as noted above.
Yes sir. Trade secret stuff.
Did you say once? Bring in the Black Hawks or words to that affect?
The MSDS I recall mentioned protected formulas. Secret stuff. Never
clear to the consumer.
"I don't have anything against work. I just figure, why deprive somebody who
really loves it."
Actually, you are quite wrong. It is NOT required to list ingredients and
range. It is only required to list HAZARDOUS ingredients. You can
avoid registering inert compounds, if you wish.
WTF are you talking about? You've checked 3 different Rain-X branded
products (washer fluid, original, and "windshield wax") plus one
completely un-related product that isn't even Rain-X! Of COURSE the
formulations are different! Sheesh.
Sell the car. You're too stupid to own one.
1) you couldn't handle instructions written for somebody with a 4th grade
education and successfully followed by a hundred thousand people. You used
too fucking much.
2) you couldn't figure out how to open a web browser, point it to a search
site like google, and then come up with a clever search string like "how
does an idiot like me remove rain-x?"
Or perhaps just the last two words; first match:
It's water soluble. Use water and a cotton cloth.
I doubt Rain-X is the culprit. If applied properly, Rain-X is VERY good at
what it is designed to do -- let rainwater blow off the windshield in the
airstream without using wipers. "Spotty" film could be the result of tree
sap, pollen, bugs, tar or a combination.
Instead of trying to use the wipers to clean the windshield, clean it by
hand thoroughly, then get new wiper blades. You may have to use an ammonia
cleaner or other "heavy duty" cleaner along with a nylon scrubber pad.
Once the windshield is clean, you can try Rain-X if you want. However, do
NOT apply Rain-X to a dirty windshield! It won't "fix" ANYthing!

Funny thing, today it was damp enough for fog to be on the inside and I
noticed even the inside had the spotty film. It's BOTH on the inside and on
the outside. Jeeeezus.
I tried the brake cleaner for about 20 minutes and I hope that works. I
rubbed with a white towel and applied the brake cleaner from a spray can.
The stuff dries pretty quickly so I had to keep applying it. You can get
high in my car now, just sitting there, so I left the windows open. We'll
see if it works to get rid of whatever it is that is smeared on both the
inside and the outside of the windshield.
I have found that Rain-X is best used by someone who spends a lot of time
on the highway - not piddling around town.
It works best at speeds OVER 35 m.p.h., but, as you are experiencing, tends
to create a "haze" when using the wipers.
But, you wouldn't believe how well it works on the highway - especially
when passing a tractor-trailer and driving through the "rooster tail" with
the wipers turned OFF!
When I traveled heavily, I used it. Now that I don't travel that much, I
don't use it any more.
I would think that Rain-X shouldn't be sold much in coastal California
since it almost never rains here. Yes, the song is wrong. When it does
rain, it just drizzles all day. So Rain-X is all bad and never gets to be
I grew up in Florida so I certainly know what real rain is. Out here in
California, it won't rain a drop for ten months, and then for two months,
there's wet air for weeks. But not really rain. I've been here five years
now and haven't seen a real rain yet.
Point is, I want to get that horrid rain-x off my windshield!
I sure hope the brake cleaner, recommended by Kraagen, works. Time will
I used a glass cleaning product from the FLAPS that has some clay dispersed
in a solvent system. The clay is not abrasive to glass, but provides a
area which helps compete for the surface active materials in RainX and the
No magic bullet...just elbow grease.
For all those who like RainX, good on ya'. I dont. I applied it properly,
and just dont like the effect.
