Windshield Wiper Chatter

I use something of a little of all the above. I apply old fashioned rain-x to all the glass regularly. Use rain-x windshield washer fluid in the tank. And I keep a spray bottle of rain-x WW fluid in the tool box of the truck. I like to start each day out with a clean windshield, so I use the spray bottle and a old terry towel to clean the windshield before hitting the road for the day.
Been using rain-x since the 70's.
