I Raise the pitch...on the pitch raise.

[Dan M. Hallett, Jr.]

Dan,

Liquid Wrench is a petroleum product that dissolves or at least
loosens up rust somewhat...If I come across rusty pins and coils
the drop of Liquid Wrench is probably just a insurance policy.
It calms my nerves anyway.  No not a drop in my mouth but on the
rust.
