About two weeks ago, I had my car in the dealer svc dept for some wty work and maintenance items. Because I was on the road, and didn't feel like bothering, I gritted my teeth, and had them install new wiper blades (sidenote: I was amazed at the non-rape I experienced; only $11 for two blades, installed, at an Infiniti dealer, no less!). Anyway, they worked fine and smoothly on my Rain-X coated windshield until a few days ago. BTW, I don't use them much, as the RX coating works well enough by itself 90% of the time. Then, on a recent road trip, I ran out of wash fluid, and refilled with Prestone bug removing windshield wash. It's great at removing the remains of swarms of love bugs, but shortly after starting to use it, my blades started sticking to the glass so badly, I can hardly use them. They buck and chatter so bad, I'm afraid I'm going to harm the system. I've washed and washed the blades and the glass, and even scrubbed the glass down with acetone, but the darned blades still stick and chatter. Anyone got any brilliant ideas before I pony up for another set of new blades??? Thanks for any assistance. Of course, I've purged out all the Prestone crap, and will never try that stuff again.
