I know this has been mentioned a few times already, but I tried Bon Ami as a last resort and scrubbed the living heck out of my windshield. That was 2 months ago and I've driven in 3 or 4 rainstorms since then with no issues. Can't say they're butter-smooth as the GLC wiper system appears to be garbage, but Bon Ami seems to be the fix for me.

Hope this helps someone else as this issue is incredibly frustrating (and dangerous as well).

They are available. Bosch AEROTWIN A 843 S.

Good find. I located them on Amazon listed as the Bosch 3397009843. Are these the OEMs? Or a better version?

Don't know, but they fit and don't come with the MB tax.
