The cellophane like elements are plastic film trapped following the
vacuum bagging process. The edge of the film sometimes gets trapped in
the edges of the glass and comes away with the work piece. I had heaps
of it around my mouldings. A sharp craft knife and patience will get rid
of them.
All of the PVA will have been removed if you gave it a good scrub with
water. A liquid alkaline soap followed by a water wash (see
www.polyfibre.com) will do an even better job of cleaning the
mouldings.

Subject: europa-pva release agent
the pva realese agent appears to be clear and therefore difficult to
be sure if it is fully removed.
i have tried scrubbing with an abrasive pad/hot water but some
'cellophane' like elements remain
some builders seem to use vinigar. would it be possible to dye the
pva say billiant vermillion or similar
so that one could be sure that it is fully removed
