Wiper "chatter" what gives >>

[Jeff02GAGT]

I just installed some new BOSCH windshield Wiper Blades.... I got the top of the line ones that have the teflon coating on them.. I paid like $25 for the two blades. I goto use them today (first rainfall since putting them on a couple of weeks ago) and MAJOR chatter across the windshield. BOTH OF them are doing this. When I got home, I took some rubbing alcohol on a cloth and tried to wipe them down. Lots of dirt came off, but they're still chattering across the windshield. This is REALLY driving me crazy.. What causes this, and HOW can I get this to stop???

You could

Oil them with Mobil 1.

I use Rain X and good wipers (I have the Bosche too). No chatter here.

Crud that buils up on the windshield can cause chatter. Completely clean the glass and give it a coat of rain-x, you'll be fine.
