Greg,<div>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."</div>
