Cleaning the OUTSIDE of your windshield...

Clean it with Bon Ami or Bar Keepers Friend (NO COMET OR SOFT SCRUB).

I'll second that. I'll also go as far as to say that I don't like RainX, Aquapel, or any type of wax or sealant on my windshield. I have never used that stuff and not had streaking and chatter problems. If the window is good and clean, I don't think you need to put other stuff on it. Personal preference, I know, but even if I am of average intelligence, I am smarter than 50% of the people out there. :)
 
i had that issue and my arm was very very slightly bent,replaced it and it stopped, inspect it well as it doesnt take much to throw them off
