No!  No!  No!  Whatever you do, never use less than 99%!  Anything less
has significant water content to cause long-term oxidation of the metal
components in the mechanism (i.e. heads, capistan(s)) and thus wouldn't
be a terribly good idea.  Anyway, every drug store has the stuff and at
just over $1 for 16 fl. oz., it really isn't out of the price range for
most audiophiles.  I've heard of people using liquid freon, but can't
see any distinct advantages to this...

NO!  All discwasher fluid is is DI water.  As stated earlier, water will
oxidize.  BAD NEWS!
