"clearing" cell culture inserts

[Mike Garbutt]

Dear netters,
I read in a journal (that I'm trying to find again) that polycarbonate 
([Costar] translucent) cell culture inserts could be made transparent by 
addition of some solvent/solution, acetone or chloroform or something like 
that? for the purpose of visualizing cells (that can not be otherwise seen). 
Does anyone know how to make translucent polycarbonate inserts (or PET 
[Falcon] inserts) transparent?

Thanks, Mike.
