Cleaning marks usually mean a lot of fine scratches. If
there are enough they can act just like a diffuser over the
lens. The effect can be subtle and, perhaps, not noticable
until the lens is compared with another without the
scratches. John van Stelten does this work. Its not cheap.
The cost will depend on which lens it is, he can probably
give you some clue as the the price via e-mail although I am
sure he will want to examine it to be sure. Also keep in
mind that getting the front cell out of a Rolleiflex
requires some disassembly of the camera.
