Hi Geoff, No, the dc will keep humidity lower and slow down the rust. You might wish to increase the dehumidifying capacity by adding more rods.

The water tank support rails had literally rusted away and the tank had fallen out. Did I say it u was old? Anyway, at the same time I also replaced two broken strings up in the high treble. The entire piano was on the rusty side and my guess is that age along with rust had caused these two strings to break. > >On a return visit last weekend I found another string up in the high treble had broken.

She tends to be cold most of the time so the forced air heating system runs a lot. While the vent in the piano room is blocked, there is a sliding glass door that is infrequently open leading to the outside. All in all not what I would call an environment that would be rust promoting. > >Could the DC system be causing the rust?
