on close inspection it seems the front coating has somehow degraded into this , so should polishing off the coating improve image performance?? _________________ Cameras-Point and shoot- Powershot A590IS Mirroless-SONY NEX-3

You probably have nothing to lose in polishing the coating off, maybe that is the problem. _________________ LENSES & CAMERAS FOR SALE.....

Sometimes.
Depends on the nature of the haze.
Easiest is condensed lubricant. This can usually be cleaned if you use the right solvent.
In order, I would use -
Alcohol
Naptha (lighter fluid)
Acetone
If these don't work then you may try harsher measures, such as a glass polisher.
Some people have used ordinary toothpaste for this, I suppose the white kind not the gel kind. That has a fine abrasive in it.
Some have used cigarette ash.
I have even used metal polish.
The Komura TC isn't valuable so its a good one to try this sort of thing.
To remove coating + haze, this stuff has often worked for me.

It looks quite similar to my Kaleinar 5B. One of the elements looked like it had a secondary, mat like coating on it. It did clean up a bit, but I was not able to remove it completely. My guess was that the coating was not applied properly in the factory, which, in time, led to it`s separation from the lens. I think this because my Kaleinar came in the original box, unused, from the person who bought it. I do not think you`d be doing too much damage by removing the coating completely. Before you do that, you can also try using hand/cold cream. It does wonders when it comes to fungus. _________________ I have many great Russian cameras and lenses for sale on my ebay account, please check it out: http://www.ebay.com/sch/piksius/m.html?_nkw=&_armrs=1&_from=&_ipg=25&_trksid=p3686
