Re: sx64 repair / C=Key

As the sole and founding member of the Antipodean Floppy disk reformation and
reclamation association, I've also had some success with removal of
the disk from it's old sleeve, and cleaning radially with some of
those surgical alcohol swabs (in convenient, individual
condom-wrapper-sized packets). Pharmacists sell them very cheaply in
boxes of 100.

A genteel, non-violent method is recommended, or a rust-free, clean
mylar sheet can otherwise result (in the case of flaky media). Soapy
water works better, however, if fungal damage is present.
With care, (and an open 1541) is IS possible to run the disks without
the sleeve - this can reduce media wear when scraping the data quickly
from a dying disk.
