I know basically what one needs is a *very* fine abrasive followed by
polishing - or even just polishing as that is just the next level of
fineness really. But what polishes etc. have I already got which
might work on plastic lenses? Would something like T-Cut be too
fierce?

I have heard that Brasso works. But wait for some other responses
before starting.
Brasso, or jewellers' rouge - which probably isn't all that readily
available. It will affect any coatings on the lens, though.

Thanks, yes I had this vague memory that metal polish was the thing to
try. These aren't coated lenses, or at least if they were the coating
has long gone. They're not photographic or high resolution lenses so
incredible precision isn't an issue.

Many years ago I used Brasso wadding to lightly polish out a scratch in
a perspex looking record deck cover. I can still remember the horror of
watching the small scratch widen into a crack that propagated straight
through the material. I assume the solvent in the wadding was to blame.

I was talking about the stuff that is liquid in a tin. (Never crossed my
mind that there are two sorts of Brasso - which there are - and still
less that someone would use it for this purpose.)
