RAIN-X Wiper Fluid Additive - Testing, Review, and Results! 

Rain-X actually works better than you were able to show. With the Rain-X on the windshield it makes it so the rain rolls up and off the glass from the air pressure caused when actually driving. I use it all the time and I really don't need my wipers at all when driving around 40 mph or higher, the rain just whisks right up off the windshield... Great video. Thanks!

My wipers failed and I used the one where you spray on and buff the windshield. Worked great. I was able to drive in rain. Below 40 mph droplets did not clear. I think this was due to the aerodynamics of the car.

I use turtle wax on my windshield and glass. It lasts longer than the rub-on rainX. The only rainX I use is the orange windshield wash

The more you use it the better it works. Make sure to clean the wipers. Also, the bugs do not stick as bad. I also add a squirt of dish soap to my washer fluid jug, shake it then put it in the washer fluid reservoir, which really helps get a cleaner windshield.

Rain-X works so well, it should be a safety requirement.

So what’s the different between adding water or not water

Is it ok to mix rain-x additive w/rain-x washer fluid??

Oh, that's bad. Very bad. When you use the wipers with the rain x you can see the windscreen completely fogging up briefly. That is absolutely horrible when driving at night, through rain. Not only does the rain make it hard to see, but that fogging up will blind you with the headlights of oncoming traffic. Based on that alone i wouldn't recommend this at all.

placebo

I put the whole bottle in mine lol

Can u use this on the whole car not just the windshield ?

Great video and review

I accidentally put double the dose, I'll be back with an update.
