Rain-X Washer Fluid - Are the problems real?

Let me start by saying I don't like the Rain-X that you rub onto the windshield. In my experience it causes streaks and sometimes it makes the wiper blades skip across the windshield. The last time I used it was 15+ years ago so maybe it's gotten better.

I love the Rain-X washer fluid because it applies itself every time you spray your windshield. You just keep the tank full and forget about it. It works wonders in heavy rain. In situations where you would have near zero visibility, it allows you to see perfectly. It makes the car much safer to drive.

I've used the orange Rain-X washer fluid religiously on all my cars for many years and never had a problem. This includes 3 years on a leased F36. But now, some people are warning that using this type of washer fluid will ruin the sensor in the reservoir tank, leading to costly repair bills.

Does anybody here have any first or second hand knowledge about this? Like myself, has anybody else used this in their BMW's in the past without having any problems?

Yes, that stuff does not get along with BMW's system. There is a note about it on the owner's manual. If you use it and it damagers the sensors BMW will not cover it under warranty.

So, is OEM BMW fluid like Rain X and provide the same effects? Or, is it like any cheap blue stuff out at the stores?

The OEM fluid is just regular fluid, like the cheap blue stuff at Walmart. It doesn't have any water repelling effects like RAIN-X.

The BMW washer fluid is great if you live in a warmer climate. If colder climate, at $4 a bottle, this stuff gets expensive.

Well, that's disappointing news completely. Rain X vs cheap blue stuff is night and day difference.

I didn't believe it as well until I decided to just try it out on my E90 last winter. Affected the pump and had to replace it. Will stick to the windshield application instead of the actual fluid.

Will streaking occur/damage to wiper blades occur if using the 2in1 RainX window cleaner on external windshield and using normal OEM recommended BMW windshield fluid?

Yes, it ruins our washer sensor. I used Rain-X for years on various vehicles (Lexus/Toyota/Honda/Mazda) and had no issues. So I never thought twice about using it my car.

Now my "Low Washer Fluid" warning remains on, even though the reservoir is full. I will never use Rain-X again. I have only had my car for 7 months. I should have researched before using
