Mystery stains on glass....How do you clean these ??

[AR67GTX]

FYI - This may have already been mentioned. I noticed Groits listed some special 3” & 6” pads for orbitals for polishing glass for removal of water spots. They also have a special polish to use with them. I haven’t had a chance to use it yet. The polish appears to be cerium oxide but is pretty creamy. Not advertised for anything but light scuffs and water spots.

That’s a good idea ,just round off the ends on the blade , it’s helps prevent scratching the glass.
