@rich121,yes have seen this myself too on a few earlier releases from Cisco and a few Classic records. Once I found this on one, ditched the inner sleeve on all of the records from that vendor and replaced with new discwasher type sleeves.
Also of note if you have any of the music matters 45 rpm pressings with the light pink inner sleeves, get rid of them and replace with something better. they will leach plasticizer deposits on the vinyl over time,.
if you have any London Decca records with their original sleeve, (the clear plastic pvc type) replace those as well, they will leach plasticizer from the sleeve onto the vinyl.
As far as removing it, pretty tough....have not had much luck with any mild solvents.
If you find something that works, please post....
thanks
