Well put, Greg. Thanks for the thoughtful and technically knowledgeable
comments from a professional chemist. With replies on this subject all over
the map, I was beginning to feel badly for ever suggesting 1,1,1
Trichloroethane. I use it - but very carefully, and only when nothing else
will work. It's especially handy in the spray can for things such as
degunking right-angle gear assemblies, gear trains, and such in old radios.
It is such a good degreasing agent one must pay attention to relubing right
away for "rustable" metals. I nearly ruined the trigger/sear mechanism of my
favorite blackpowder rifle several years ago by not paying attention to
that! Back to towers...
