Here in "The South", rusty strings and pins are the norm. I've hitherto simply cleaned the strings by rubbing with a gray or red ScotchBrite(TM) pad, and then wiping with paper towels dampened with naptha, but am wondering if something could be aded to the process that: A) Helps get the rust off B) Leaves a thin film that is rust-inhibitive without killing the tone C) Doesn't leave a weird odor in the piano And as far as the pins go: I was going to order a "Travis Tuning Pin and Coil Cleaner" kit from Schaff, but was told that a new manufacturer would be supplying them " in a couple of weeks". So I'm intending to try chucking a gun-cleaning brush in a cheap drill, and going at them with that. Comments appreciated! Thumpe Sent from Yahoo! Mail for iPad |

Why would anyone want to clean a rusty tuning pin? Seriously! I never have understood that.
Thanks, Oleg! Of course we've all heard pianos with VERY rusty strings that sound terrible (and obviously on account of it) so why would anyone suggest that pianos with moderately rusty strings wouldn't sound moderately bad? (Some people just like to be disagreeable, apparently.) Thumpe P.S. The "obviously" above is also proven, because when a string breaks on such a piano, and is replaced with a new one, the new one sounds markedly better! |

Hello I do not have some brand or name but I asked that question at the IRCAM when I was working for them, and they provided me an extra thin product that dried and did not leave a messy stuff (catching dust) as does WD40. However they affirmed me it was the same kind of moisture barrier product. The strings could be lightly oile (I know some will cry !) knowing that dust will be glued on them then (even if "traces" of oil are used.Also what I have been told is that all oils degrade in time to a product that is really sticky.I do not agree that the corrosion have no effect on tone. The main problem is that it cannot be cleaned above and under, then if rusted strings are cleaned, only on the apparent part and only on the top, they sound even less good after that. Unfortunately , I suppose that once there is really rust, the metal surface is not polished anymore.We also have a very unfortunate situation due to the steel used today.Old strings produced with cast steel did not oxyde and corrode as the ones of today.sight...

I noticed how resistive to corrosion some older wire qualities where, before recycling times so not so far from now. An East German upright from the 80's refuse to rust while being 50 meters from the Atlantic in an unheated house in Normandy, other samples with old pianos, A 220 grand Seiler 15 years old looked as if it had 60 years, strings wise, horrible harsh tone on a very recent piano due o rust.
I have read that the purity of the steel would go along with corrosion resistance, that some "electrical" effect between metal particules could be in cause. Not knowing enough about steel to sy more I would appreciate any comment.
The wire could be also potected by adding a coat. My be simply the lead baths used in the process was adding something, (I doubt lead is yet used today) but the polioshing may tear it off...
Sometime I wonder if changing the plain strings is so much advantagous when the piano is in humid climate, then...
Roslau propose a corrosion treated quality, but no one seem to use or sell it anymore (if i am not wrong)
Sorry for the typos, cell phones, no typing correction that would not change the meaning, in my case (Android)
AHA! FINALLY, a concise, informative, intelligent-sounding and "Snark-Free" answer. THAT's what this forum is supposed to be for! (Thank you, Blaine!) |

Which brings up another question: the mill oil that is on the music wire as we get it. Would it inhibit corrosion (being an oil) or encourage it (being an acid)? Maybe we should soak our coils of music wire in paint cans full of lacquer thinner prior to use? I don't do that now, but do wipe the black stuff off it when I'm stringing, with a nearby roll of paper towels. |

Great! Thanks Ron! I actually HAVE bought the IG wire, and just have not used it, yet. (So wasn't sure of its slime factor.) Thumpe P.S. It is my understanding that most "mill grease" is in fact lard. (Blechhh!) As a 40 year spiritual vegetarian, something additionally gross, to me! (I "Purple Power" any structural metal I buy.) |

About brass parts I lacquer them with a specific lacquer sold by Rennet. Excellent flow, invisible once dry, and resist friction (pedals) there are solvents but not Nitro type.
The old "Zapon lack" was used on metal, simply cellulose in solvent (nitro style). It was known that brass tarnished under it many colleagues stopped lacquering brass because of that. But that Renner recipe is just perfect.
Your tip about strings will be tested ;)
