Just apply it to the glass directly instead. Problem solved.

Update from my previous post

I used the yellow Rain-X washer fluid the first time and it messed up my washer fluid level sensor. The warning for low washer fluid would not go away.

I drove around and literally kept spraying my windshield until the tank was empty. I then filled it with the BMW washer fluid (purple one) and the next day, the low washer fluid went away. I was very lucky that I did not have to pay to change the sensor. The sensor sits inside the reservoir and the Rain-X fluid coats the sensor, causing it to think the reservoir is empty, even though it is not.

I am sticking with the BMW washer fluid only from now.

IDK guys, but I go through 40 gallons of Wal Mart Supertech purple and blue stuff each winter and never had issues on E70 and E90.
Ran Rain-X on E90 on a road trip, never had issues.
