[silence] bowed piano question

[Caleb Deupree]

Hello all,

One of Cage's number pieces, Fourteen, used a bowed piano, so I'm  
hoping that some of you may have worked with one of these  
instruments.   After considerable trial and error, I've gotten some  
decent sounds from a bowed piano, but I see rosin on the strings.   
How can I clean the rosin off the strings inside the piano?

Thanks.
