rusted piano strings

[Paul McCloud]

Hi, Mark:
	You can use a "polita cake", or other abrasive media to remove the rust. 
Polita looks like a rubber eraser, with abrasive particles embedded in it. 
Rub it on the strings (not bass strings) and it will remove the rust. 
Areas near bridge pins can be cleaned with a brush attachment on a Dremel
tool.  A larger rotary steel brush in an electric drill can clean around
the tuning pins.  I use steel wool on the bass strings.  Be sure to wear a
dust mask and goggles.  Have fun!
