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.

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. Wim 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.
