Whole room humidity control better than Dampp Chaser. ( Right?)

[Greg Newell]

Patrick,

I completely agree. My post, however, was dealing with the prevention of
oxidation and/or rust not the promotion of it. A DC unit in a grand won’t do
much to prevent it. One could argue that the string cover will retain some
of the DC unit’s effects but it seems to me that little is afforded here
since the only pass through from the underside of the soundboard to the top
side are through the nose bolt holes. I doubt that the amount of air passing
through these holes in the board are enough to effect much of a change
topside.

Greg,

My (anecdotal) observation is that a standard DC installation on a grand
will not promote oxidation of steel strings and copper windings, while usage
of a room humidifier often will result in rapid accumulation of rust & dull
brown copper windings. If customers are inclined to use a room humidifier I
urge them to keep the lid closed when not in use. Customers sometimes blast
the mist right into the piano -- sigh -- they think they're "doing the right
thing."

 I believe that it's even a bit of a stretch to claim that it helps to
prevent rusty strings in a grand as the pictures would seems to indicate.
