I've been using Rain-X Pink/Orange fluid almost exclusivley since the factory fill ran dry. We've been below 20F this entire week and not a problem with the fluid freezing.
Owner reviews for washer fluid
green prestonee w/w fluid w/ antifreeze ,dont know if it harms the paint,havnt noticed it on my two passats that i use it in, anyway w/the underhhod heat generated it wont stay rozen long
I used Mercedes Benz concentrate, its the only fluid ths works with my wife's silly single wiper system. My problem has been solved!!
might as well get rid of the VW washer fluid. It contains the Rain-X stuff also. I personally always have good experience with Rain-X.
Confirmed: Orange RainX is the problem I called Rainex and after negotiating the maze that is their company phone system, I spoke to someone who seemed to know all about the problem. She said they were reformulating the product to avoid this going forwards. According to them, the sensor is not damaged by the orange Rainx but rather the sensor is "blocked" by the orange deposit.
A few weeks ago I was running out of washer fluid and decided to refill with rainx de-icer since it was on sale, it's been very cold and I wasn't planning on bringing my car in for service for a while. Last week the wash fluid light came on again.
