WD40

[Farrell]

A very well respected tech in my area puts a very light coat of WD40 on the
strings of a freshly strung piano to discourage rust. My recollection is
that he puts a little bit on a rag and gently wipes the strings. I find it
hard to imagine that such a little bit is going to find its way to the
pinblock and cause problems. I don't do it - I just figure its best to
simply keep the humidity down.

Although I do remember when I was taking the Potter course and just starting
to learn tuning, I was out shopping for an old beater piano for practice. I
found an old upright a tech (or was it hack?) was selling. We opened it up
and when I played it many of the hammers did not return to their resting
position. Well, a half-can of WD40 later sprayed liberally in the general
direction of the piano action and keys, and all was back in good working
order! Even at that stage of my budding career, my gut told me to avoid
doing business with this bozo.
