Thank you for the comprehensive write-up. I do suspect the substance
on the windows is some sort of smoke or pollution residue.

I've heard/read somewhere that slices of apples work well for this
cleaning as well. Rub the apple against the window and wipe clean.
Just don't eat the apples afterward... :-) I guess there's something
about the acid in the fruits that makes this work.

I think I'll try your "Key West Method". It could potential leave the
car smelling lemon fresh...
