Just an observation...If you are taking polaroid pictures,
or the person before you has, and has left them face down
on the transilluminator for a while....
....then you can sometimes see the crusty areas showing
blue fluorescence.....or so I believe..I haven't tested
this exhaustively :)...I take it this is a product of the
corrosive developer gunk (or its reaction to whatever
other nasties end up on the face of the trans/r...)
Cleaning the tr/r with water or ethanol works well :)
