washer fluid
It seems ever since I've been using the rain-x de-icer windshield washer fluid I frequently get a "washer fluid low" warning no matter how much fluid is in the reservoir. Anybody have a similar issue?

Supposedly the de-ionized water in the RainX washer fluid can cause this issue. I also use this fluid in the winter but have not had this issue. MB says not to use deionized (distilled) water, as it affects the sensor for the fluid level.
