I thought I’d try writing back an image but got a lot of CRC errors. Closer inspection of the disk itself shows this - http://www.binarydinosaurs.co.uk/8inchFloppyImaging-7.jpg <http://www.binarydinosaurs.co.uk/8inchFloppyImaging-7.jpg> - which looks like damp.>

If it was me I certainly would attempt cleaning, after all it was unreadable anyway. Perhaps try cleaning a test area with a cotton bud (Q-tip)
and isopropyl alcohol. If the stuff comes off without oxide removal then I'd slice the top edge off the jacket to remove (with clean disposable
gloves on a lint-free surface) and clean the whole disc and finally put into a clean jacket.
