color:#1F497D'>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.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'>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."<o:p></o:p></p>
