We polished piano strings at Broadwoods with a carborundum ink eraser.    I'll show my age, that was 65 years ago!!    You will of course try 0000wire wool Martin.    Regarding your storage, I have never had problems with my paper stored strings in my tuning bag and would say there is damp and humidity around in you home or shop.
