RainBrella Review

RainBrella (marketed as “Wipe New RainBrella”) is advertised as an “umbrella” for your car, as it supposedly repels water and mud from your windshield. It is applied by simply wiping it on, then wiping it off.

The package contains two one-time use wipes. The fact that it comes in disposable wipes is probably a feature that will divide consumers regarding the usefulness of RainBrella. The convenient pouches are a great way to store these for when you need them, especially if you’re on the road. They also allow you to easily apply the product without the need to use a towel.

There are those, however, that may feel that the amount of ingredients they get for the price may not seem appropriate. Those are the consumers who may not feel that RainBrella is a good fit for them.

Whether or not two disposable pouches for $7-$15 are a better deal than a $5 bottle of Rain-X is where some consumers will probably split on this product, even if RainBrella were to last longer.

I found the smell when opening the package to be quite harsh, almost reminiscent of a strong tequila odor, only not as pleasant. The instructions do state to apply RainBrella in an area with good ventilation, and I can see why.

There is a pair of blue plastic gloves you are to use when handling Rainbrella, as well as a microfiber cloth used to wipe off the windshield. The instructions state to apply RainBrella to the windshield, wait 5 minutes, wipe off with the cloth, wait 10 minutes, and repeat the process a second time – using the same pad you used for the first coat.

I found that RainBrella does repel water and dirt pretty well, especially at first. I’m not sure it lasts as long as the advertising states, at least in the dry climate of Las Vegas. As you can see in the video below, when a rain storm hit my area 44 days after applying RainBrella, it was difficult to see if there was any benefit. I would have thought that a product advertised to last 100 washes should have worked longer than 44 days. That said, perhaps sitting in the dry warm air of Southern Nevada shortened the amount of time that it works.

While it worked, it worked well.

RainBrella should work as well or better than similar glass treatments, although you will only get two uses out of the box. I don’t know if the difference over the competition is as stark as the advertising seems to imply, but it does work pretty well.

The ingredients of RainBrella include isopropyl alcohol, methyl ethyl ketone, and inorganic acids.

RainBrella is clearly aimed at competing against Rain-X, which is a popular glass treatment product that can be found online and in stores for about $5. The Rain-X Water Repellent Wipes are perhaps the closest I found to RainBrella, and can be found for about $5 each.

    Has anyone used this and had a cloudy windshield when using your wipers? That’s the one thing about rain-x I dislike, it leave a cloudy film when wipers are. Going and defeats the purpose of a clear windshield.

    • Curtis A Baker

      If your windshield got cloudy when using the wipers, you applied the RainX improperly. I have used RainX for 20+ years and only had this happen one time. Tip. After applying the RainX, clean your wiper blade rubber edges with the rainX also.

      • BUY SOLAR!

        As a side note. Every once in a while go ahead and clean the blades off with denatured alcohol … here’s a link. Keep wiping until no more black is coming off onto the rag. ONLY USE “DENATURED”

        Re: IPA on window and wiper blades? No, no, no…

        I have read in a few places that the diluted IPA you buy tends to
        leave a residue. This is what causes the problem, not the IPA itself.
        Stoner’s Glass Cleaner and Windex, both contain IPA, but I doubt it is
        the diluted stuff you and I go and buy at the local store which seems to
        be the problem. I did try 91%, and I still had a problem.

        The other thing I read though, was about someone who worked in a glass
        factory. They used either Sprayway Glass Cleaner, or denatured alcohol
        for the tough stuff. I have seen other sites about automotive glass,
        which recommend denatured alcohol over IPA.

        Denatured alcohol says specifically on the can that it is made to clean
        glass, whereas IPA does not. Denatured alcohol is used in the
        production of rubber (wiper blades). Most windshield cleaners,
        de-icers, glass cleaners and so on use denatured alcohol. It is also
        in Rain-X. Rain-X uses it, supposedly, as a type a surface cleaner
        while you are applying it. Sort of like the mild cleaners in NXT to
        help it bond to the paint better. Everywhere I look though, it’s
        denatured alcohol.

        I have yet to pinpoint the exact cause by looking about, but I have had
        it happen before when I wiped the blades down with IPA. Just to be
        clear, this is on three different cars all on separate occasions. This
        last time just prompted me to find out what was going on. Before, I
        ended up replacing the blades because it drove me nuts, and the problem
        was gone. The only thing I did to those blades was wiping them down
        with IPA.

        I did find this…

        Methanol has 1 carbon atoms, 3 hydrogen atoms, and an -OH (alcohol functionality).

        Ethanol has 2 carbon atoms, 5 hydrogens, and an -OH attached to one of the carbons.

        Iso-Propanol has 3 carbon atoms, 8 hydrogens, and an -OH attached to
        the second carbon in the chain. The -OH is “like” HOH, which is water,
        so it is extremely soluble in water. The carbons are “like” the
        solvents in paints, oils, and grease, and cause the alcohols to be
        soluable in them to varying degrees.

        Methanol is used in windshield washer fluid to cut road film on the
        windshield and to prevent the washer fluid from freezing. Washer fluid
        is water with methanol added.

        Ethanol is derived most often from the fermentation of biomass
        (starches and sugars) and is consumable. Since the government wants to
        tax everything that is enjoyable or sinful, you get to pay taxes on a
        “proof gallon”, which is actually twice an actual gallon. 80 proof
        alcohol is 40% by volume. Denaturing grain alcohol is a way to make
        this useful solvent unfit for consumption and to avoid having to pay
        taxes on it. Even so, it is strictly regulated and inspected by the

        Isopropanol has a larger carbon chain and is different in that the
        alcohol functionality (-OH) is in the middle of the molecule instead of
        on the end. You remember the smell from doctors’ offices where it is
        used to sterilize instruments and your skin before you get poked. It is
        toxic to drink. It reacts differently than both methanol and ethanol
        to various organic compounds (paints, oils, adhesives, plastics).

        I hope this isn’t too much information, but they are significantly different and therefore uniquely versatile.

    I highly doubt this stuff will beat a fresh coat of Rain X, but I bought a package to try it out.

    • Jerrod M Glaski

      So what is your conclusion of the Rust-Oleum compared to the Rain-X

      • expert

        I like the Rain-X much better — much cheaper, seems to be more effective too.

  • JRS

    RainX leaves a cloudy film on the windows of my car. You have to clean it several times before it starts to go away.

  • dene

    MEK is an strong solvent, it will dissolve paint…..

  • Rob Loid

    I have tried most of the other products though I have not tried this one. However, going by the reviewer it seems like it is a little pricey for something that lasts less than 2 months. I use Aquapel on my windshield and while it may take a little effort to get it on (actually wiped off for the second step) I love that it lasts about 6 months, in Canada with harsh winters and lots of road salt. Though I think the $5 to $7 dollars per treatment is a good deal, my favourite part is only having to apply it twice per year.
