Lube for plastic flanges?

[RustRazor@AOL.COM]

I once tried Protek on a piano with plastic action centers, but it didn't 
happen to work.  The lubricant is supposed to interact with the pin and 
bushing, so I don't necessarily believe that plastic vs. wood has that much 
to do with it.  If Protek won't work, you can try an alcohol/water solution 
(50/50) and leave it overnight.  If THAT doesn't work it means repinning, in 
which case you may want to replace the flanges all together, whether they are 
breaking right now or not.

I, personally, will not work on a piano with breaking plastic flanges because 
when you fix one thing another breaks, and sometimes the flanges are so shot 
that they break under normal playing conditions.  GOOD LUCK!!!
