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.=20

I recommend LPS-1 lubricant, rather than Liquid Wrench. The later, stays

however, the impact thingee is not an aid, IMO. (?)
