I thought that it was not polished out, because I could see very small glittery flecks on checking with a laser light. That is the reflection on top of the glass. After each session of half an hour, I hose down the glass with town water, wash down with distilled water in a squeeze spray bottle and then with 70% alcohol from the spray bottle. I let this dry in the air and put it down flat. I use lens clean from my eye glasses supply and wipe it down with a very soft cloth, like velvet. I could see not difference in the polish after the last time. I tried shining the laser on the glass and wing it with a lens tissue and found that the flecks can be shifted with the tissue, they move when wiped. So I have lint after all the things I did.
Could you tell me how to get rid of the lint to see if the glass is indeed polished out. What do you use to wipe down the glass?

Did you make yourself a custom interferometer? Do you use a sodium light or diffuse the light from a laser?
