I get the same thing on my jeep. I'm Seattle area also. I usually will take a dry rag to a wet blade and pinch the blade real hard well I slide it down.. It helps a bit. Combined with rain x. I don't know what it is though, I can wash the rig and scrub the glass clean and clean water comes off fine no haze but rain water seems to make it worse on mine..
