Puzzler: instant rust

Listers,

I had a tuning today on a brand new Kawai RX-3 6 foot 2 grand.  The piano has 
been in the house for maybe 3 months.  It was closed up tight, but when I 
opened it, I saw that rust was already starting to form on the strings and on 
some of the pins.  I was shocked, and was at a loss to figure out how this could 
happen, especially in a house with radiant heating(that's another issue).  

It is on caster cups on a painted cement slab floor, and there are no plants 
in the room.

I had a few ideas, and I'm pretty sure I figured out the reason for this 
early oxidation, especially after talking to the rather freaked-out owner tonight.

So what, in your esteemed opinions, might this be caused by?
