Removing varnish from sheets

Hi all,

I have two sheets which were stored with a can of varnish on them (accidentally of course). The varnish leaked so now there are patches of hardened varnish on the sheets in various places (as they were coiled).

I can peel away a lot of it by hand but obviously it's soaked into the polyester sheath. I'm hesitant to use any solvent on them as I'm worried it damages the lines. The sheets are relatively new so I am prepared to put some work in to save them. Are they salvageable? What is the best way to remove this?
