[78-L] Edison Diamond Discs - Need Cleaning Advice

[Malcolm Rockwell]

Alcohol, the purer the better. I use methyl, but isopropyl or Everclear 
(ethyl - the kind you can drink) will do just as well. As long as the 
purtity approaches 100% (200 proof).
Rubbing alcohol and denatured alcohol both contain water which will be 
left after the alcohol has evaporated, and that will never do.
Windex is no good for shellac, period.
