Limey..........? We're Brassed Off....

[glatt]

When trying to loosen the stuck tuning slide of my daughter's trombone, I just held it under scalding running water. That loosened it up enough to wiggle it off, and I saw that there was lots of green corrosion that had been locking it solid. I used a scotch brite pad to clean off that corrosion, and then applied the special grease.

Anyway, the point is that hot water did wonders.
