I wouldn't worry about the corrector coatings too much, they're not fragile. Apart from DEET, ammonia and strong acids there aren't many household chemicals that will destroy them. The commercially available lens cleaners are certainly not among them.

The worst that can happen is that the cleaning fluid deposits a film on the glass, or removes grease incompletely, leaving streaks. Those can be fixed by using a better agent and/or a better technique.

There are other considerations, of course, for example: what happens if the cleaning fluid gets past the edge of the glass and into the cell/tube, will it start dissolving any rubber gaskets or spacers there?

I think the most dangerous thing to optical surfaces are particles that are being rubbed across the surface during cleaning attempts. Always use a blower first, or a soft carbon fibre brush like the ones we used to use for cleaning slides ("chromes").

Cheers
Steffen.
