I have a transparent 660 (promo for photoshops to show customers how the mechanism works) from which the plastic turned yellow from aging and sunlight. Is there a way to get it crystal clear again?

I think: no... :-(

I read once a trick for bleaching computer cases (typically : amiga).
They used dihydrogen peroxyde, IIRC.

But computer cases aren't transparent : their yellowing is on the surface only.
On a transparent case, the yellowing can be inside the plastic, too.

It's the problem of PMMA or PC with the sunlight or UV... It's the same thing for the front vehicle projector... Bad plastic without UV protector...

And it's no reversible problem...
