Interesting. I have something that looks similar on my rear window. I suspect it might be from autoglym glass polish that I failed to fully remove when i cleaned by car the other weekend. Have you used a glass paste product?

I'm going to see if more of the same stuff can take it off--invisible glass already failed.

Interested to hear if you have any success. I'd try clay before steel wool, assuming you don't have tints.
