pre-pitch raise rust treatment

[Clair Dunn]

I mostly deal with 75-100 year old pianos in an out of the shop.
I use LPS #1, a rust breaker. I spray a bit into a small
container and then using q-tips, touch each string at the top
termination point. Additionally, in really bad cases, I make my
first turn with the hammer a downturn. Often I can hear the rust
bond breaking. Then I begin to go up. Strings very rarely break.

The blurb on the can says "The fine lubricant that penetrates,
dries fast and won't attract dust or dirt." Manuf. by LPS
Laboratories in Tucker, GA 1-800-241-8334.

And, before you ask, it does not contain CFCs, chlorinated
solvents or silicones.

I believe that should have been CPL for Center Pin Lube. Yes it
will ease the rusty bearing points but I would try to keep it
away from the tuning pins.
