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All the information in there is obsolete now so I emptied it out so that I can use it to store more up to date information and the 'print' from the documents that were in the pockets have become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?
