I was wondering about using contact lens saline. I'm currently using
tap water run through a new PUR water filter.

One other question... I noticed my probe takes about 30 minutes to
provide a stable reading. My first reading with the probe showed the
must to be about 3.4 after three minutes or so. I left the probe in
the must for a good half hour and the reading VERY slowly dropped to
3.15 before stabilizing.

Is this normal??? Is the 3.15 reading reliable? I didn't know it
takes so long to register a reading using a PH meter.

Watch out for growths as Tom already mentioned, fungi other than
Saccharomyces are everywhere although this high conc of salt generally
will not grow much.

The reason I recommended heating the KCl solution is that there _was_
something growing in mine.

BTW, to rejuvenate pH probes, someone here recommended contact lens enzyme
cleaner. Sounds reasonable to me, but I haven't tried it yet. Worth a try
if the probe is otherwise junk, I'd say.
