I have rarely had the problem of strings breaking, rusty or not when I tune with care. I frequently read on this venue of those who "pulled it to pitch with a quick pass" , I don't do that even on new pianos. Some of you may remember me writing of a 179c pitch raise, using my Cybertuner, I pulled that piano to pitch first sitting, with no string breakage. It had some string rust & I did use Protek on the V-Bar via a Q-tip however I also took my time pulling it to pitch, it took about 80 minutes. Strings frequently break at the pin where they begin the turn around the pin, a stress point, pulling wire through that point rapidly during a major pitch correction, is IMHO a recipe for breaking strings. I probably do at least 6 to 8 1/2 tone or more, pitch raises a month. I do the disclaimer at each one that it's possible that strings will break, they rarely do with the exception of the cheap pianos where one expects it. I have used Protek perhaps one or 2 other times as I did on that 179c PR. I bought a 4oz. spray bottle & an 8oz. refill & still have both 8 years later. I did tune a piano for a while that had the tuning pins "cleaned" with WD-40. Initially the pins were nice & tight, with in 2 years they wouldn't hold anymore as the WD-40 had migrated fully into the block.
