[pianotech] blackening rusty tuning pins

[tnrwim at aol.com]

For more rust control-see attached photo of Zerust.
n many cases, I also put a Zerust capsule in the piano that is
uaranteed by the company to arrest further rust for two years in a
losed space of 30 cubic feet.. You should get some of these where you
ive.  It releases an odorless gas from a foam
lock in a plastic housing.The capsules are pretty cheap insurance(
nder $10 from Amazon). Ihave put quite a few in pianos for clients
ho are living on or very
ear the water where the salt air really penetrates into the house. I
an say that I
ave not had any further string breakages in those pianos.
owever, the numbers are still a bit small to be statistically significant.

Cleaning rust off the strings is fine, for cosmetic purposes. But the
ain problem with rust on the strings is at the pressure points and
he strings, like at the agraffs, the capo bars, the tuning pins,
ridge pins, etc. That is where the string breaks. So cleaning the
ins and strings is nice, but it won't prevent the string from
reaking.

learly, I can't do much about rusty strings when I find them except
o try to stop the rust from continuing. In most cases, I have caught
t before strings begin to break. The best I can do then is to arrest
he rust so it does not progress to the point of breakage, or at least
ot as quickly.
Besides the obvious cosmetic effect, stopping the rust from
rogressing is beneficial.  Converting the rust to iron tannin and
leaning the strings with a rust inhibiting oil pretty much stops the
rogression of the rust. So I think it is worth it.  It makes the
uning pins look nice too.
