Hi Don-Yes indeedy the main enzymes digest starches, but there are also
enzymes for digesting protein and fat in saliva. You also may not have
much starch on your disk either, or fat. The point I make is that a weak
enzymatic cleaner may not be effective on things found on a disk. The
average human, at least in the United States, needs something other than
saliva for cleaning their teeth. Colgate, Crest and Oral B did not invent
plaque and calculus; their products were a response to a need. I could
just as easily have included salt and bicarbonate of soda mixed half and
half. It is quite possible that someone will do research and find that
sterile saliva is the absolutely perfect record and painting cleaner. It
is also possible that there are products or formulations available already
that are as effective or more effective than saliva. More study needs to be
done, perhaps, although who would pay for it, I can't imagine. The major
point I want to make is that saliva is in effect a bio-hazard when placed
on a disk or a painting.
