I use protek. Corrosion on the strings is not uncommon here, generally the rust will be on the top of string with none or not much on the bottom, I think because of the settling of dust. If the strings are rusty to the point where I think it will have a large effect on rendering or that there could be breakage I use it. I apply it with a 1/2 inch chip-brush on the felt and front bearing points. Of course you want to steer clear of the tuning pins but also take care that it doesn't run through the agraffes to the windings of the bass strings. So I make sure the brush is fairly dry when I apply to that area. I think it helps most where the strings run across the felt. I use it mostly on grands but occasionally on uprights as well when I have reason to fear breakage.
It does help with the rendering. At the same time, all things being equal i.e. good strings and good bearing points, I have found that I don't like the feeling of the lubricated strings, they feel better dry.
But as I say, it helps the rendering with rusty strings, and I believe it provides a little insurance against breakage in such conditions.

Hi folks,
Lately I've come across pianos that have pretty awful rendering while tuning. I'd like to know how some of you handle applying Protek (or some other preferred material) to the string contact points like the agraffes and capo bar.
Thanks,
Happy Tuning!
