So while it might free up a loose flange, it will also attract dirt over a period of time that will cause the centert to freeze up again later.

I know some technicians who use it. What is the main downside of it. Another lubricant I've seen other techs use is LPS-1. An old mentor of mine used it for a lot of piano related lubricating so I used it for a while when i was starting out. However, I noticed that most high level technicians were not using it so I stopped. Anyone have thought on LPS-1?
