[pianotech] WD40 on pinblock

[Dale Erwin]

By the way...there is a guy in San Diego who has given the WD-40 or some form of lubricant treatment to what may be some thousands of piano. Yes, he has been sued and he has lost but still his thinking surely was derange.  I am replacing belly parts in a Mason A that got the treatment on the bridge ,block/tuning pin area, strings.
 Killed the tone in an other wise healthy and  fairly young piano.
Wow!

I had a well-meaning cohort who thought it        would be prudent to clean all the rust off the tuning pin coils        with WD40 and a wire wheel in a Dremel tool.  It looked real        pretty when he was done, but the pinblock was ruined.  Pins that        were already quite loose slipped their bonds and went WAAAYYY        flat.  The piano was untunable.  It had already been doped AND        treated with CA glue.  The WD40 finished if off.  Time for new        block and restringing. 
        Trouble is, it's a no-name mediocre 5-ft. grand.  Barely worth        it.

      Ouch.  What a pity.  The situation will be the same here, if the      pinblock is ruined by the WD40. The piano, though a Bechstein, is      straight strung and 100 years old, and hardly of a value that      would justify a new pinblock and restinging.
      
      Best regards,
      
      David.
