Precautions re string breakage

Geoff,
There are many different "electronic" applications/products that LPS makes. The Contact cleaner is one of them, (I think that is LPS-12?).
I've been using LPS-1 for over 30 years and have never had any adverse reactions/problems in regards to use in pianos. I ALWAYS use it when doing pitch raises and the many friction points involved. The LPS line is very consistant and readily available, (Most decent hardware stores carry it.)

Joe --

I always considered LPS to be an electrical contact cleaner/lubricant, but I checked their website and it looks like it would be relatively harmless to a piano if used carefully. As long as wicking and over spraying onto other parts can be avoided there is probably little harm that would be done. 

For more info on LPS-1 go to: http://www.lpslabs.com/Products/Lubricants/LPS1.asp

I was taught to paint a little Liquid Wrench onto the pressure bar and 
"V" bar points before attempting a pitch raise but have long since 
abandoned the practice. There are times when lubrication might help, I 
suppose, but the only times I've used it in recent memory was to improve 
the tunability of a string which was rusty and dragging on the 
understring cloth."

I recommend LPS-1 lubricant, rather than Liquid Wrench. The later, stays there, forever, and is a magnet for dust/dirt. Whereas, LPS-1, lubricates and disapates into nothingness after a few hours. Also, I've found the use of an impact tuning lever helps ease the possibility of breakage. On grands, however, the impact thingee is not an aid, IMO. (?)
