Damp chaser for loose pins

[Frank Cahill]

In Randy Potter's course, he says that Damp Chaser systems will cure
loose tuning  pins.  Bear in mind that Randy lives in the center of
Oregon where humidity can drop to 10% in the winter.  So it's possible
that what he says will indeed work where he lives. Randy's a straight
shooter so I have no reason to doubt him.

Here in VA, humidity hits 90% or more for weeks at a time in the summer.
Even with Air Conditioning, humidty will be 60-70% inside. Therefore,
the piano surely gets humid. In the winter, humidity is about 30-35% in
most homes. So I feel that damp chasers, which maintain 45% humidity,
won't do a thing for loose pins here in VA.

Anyone have any observations on this?

P.S. I'm not knocking Randy, he's a heck of nice guy and has taught me
alot. This is just something I've been curious about for a number of
years.
