Don,
I had a pH test a few years ago, which required wearing a recording device overnight connected to a sensor which stayed at the bottom of my aesophagus, just above the stomach. The stomach acid that reached it through my hiatus hernia (since repaired in a 20 minute endoscopic plication) had a pH of about 2.
Since you're an engineer, I'm sure you know that every pH number change represents a factor of ten; i.e., stomach acid is very strong, which accounts for the heartburn (and damage to the aesophagus).
David Blumberg,
In case you haven't seen this.... I recall seeing something on Naylor's web site about saliva damaging a clarinet bore, but I believe it was an unusual or rare case. If it's that corrosive it would seem reasonable to expect it to damage cane as well, but most of us probably don't need to worry about it.
