Polyethylene glycol and parchment

A valuable book of our collection (manuscript on parchment)
"suffered" a "restoration treatment" thirty years ago, with the help
of polyethylene glycol applied by immersion. Would somebody  to
predict the aging behavior of this material? Is there any possible
treatment to remove this PEG?
