Not tried myself, but may be worth a crack.

Seem to recall it sometimes said marks can be permanent, ie actually etched "into" glass, rather than a mark "on" the surface, in some cases.

Worked really well on my Jap Import car which had water spots all over the windows which just would not come off! Got it from Mitre 10.
