I have a document folder;

[Daij]

the one that has polastic polypocket-type pages to store documents, spreadsheets etc.
All the information in there is obsolete now so I emptied it out so that I can use it to store more up to date information and the 'print' from the documents that were in the pockets have become imprinted on the inside of the pockets. I have tried meths to clean this 'print' off and it doesn't work. Anyone have any ideas on a solvent/substance that will clean it so that I can re-use the folder?

Thanks in advance

If it is laser printer pigment or printers ink try white spirit.

Have a go with nail polish remover too

Isopropyl alcohol/water mix, the same as you use to clean LCD screens.

WD40 is also a good cleaner.

Eucalyptus oil or tea tree oil may work - good for removing sticky marks.
