I found a small bottle of 1,1,1 TCE at the dump today ("Typewriter*
Cleaning Fluid"). I've heard that a previous version of Tap Magic used
it and that the TCE made it far superior to the current stuff. Not used
anymore 'cause of the EPA.

Anyhow, I thought that I'd mix up my own tapping fluid with it, but
can't find a formula. Suggestions?

It isn't critical. Mix with some oil, about 10% or 20% oil in the TCE,
using whatever oil would work with the metal in question.
