Window spots only where wipers wipe?

Strange...

Sorcery. Let us know what does work, clay bar or otherwise.

Is there any chance that the type of washer fluid you are using is causing it. I just started noticing it too after I added rain-x fluid to my washer fluid. Wondering if it’s a residual of rain-x on mine??

I had a very similar situation.
I thought clay would help, but as you noted, it did not.
What did the trick was glass polishing compound on a mini DA with a cutting pad.
I first tried it by hand, but that did not work.
Gotta use the machine.
