[pianotech] Verdigris in Action Centers

[piannaman at aol.com]

 In many verdigris cases it
seems, someone has inherited a family piano, or gotten a "real deal" on
an older Steinway and they don't have the money to perform major
surgery.? Getting the piano to a semi-functional state is all they're
after.? 

I use the overkill method on actions that are basically dead but whose customers can't afford a rebuild:? 

1.? water/alcohol (I use vodka, as it has other uses as well...:-) applied to centers
2.? heat gun to dry it out 
3.? Protek

This method has lasted longer than anything else I've used as an inexpensive "fix."? I had a lady call me shortly after I left her house after using this method.? She was crying, literally.? "I can play my piano again!"?

One method that's been mentioned in the past is use of a heat gun to "melt" the green ooze out of action centers.? That, along with liberal use of CLP, as Patrick suggested, seems to work - for a while.??Like Wim and others have said, it's only temporary, holds up for about a year here in Florida, in my experience.? Keeping the customer informed is key, and sometimes leads them to commit to eventual action parts replacement (or more).

Greetings:


?


I am wondering what the latest recommendations are for severe verdigris on old Steinway Action Centers.? Reaming and repining has never to my mind been a permanent solution; therefore in the past I have tended to replace whippens and shanks.? However, in a very old Steinway when the customer is not willing to spend the money, and repining appears to be only temporary and time consuming, what type of chemical treatment has been found to be the most effective.? 


?


Any suggestions would be greatly appreciated.

Thank you,
