Good idea, Scott. Gun bore cleaners/solvents
been suggested before. What I have found out is none of the gun
cleaners are true lead solvents. It takes something like foaming nitric
acid to dent lead - of course that is lead in the metal form - something less
drastic might work on what appears to be a lead crystal form of some sort.
(If view under a magnifying glass you can see glints of light off what appears
to be crystal facets - of course, I guess it could be carbon.
In any case, I would greatly like to find
something that would remove the stuff from the ceramic cone - my belief is that
a large amplitude ultrasonic cleaner might shake/jar the deposits off the
ceramic. But, don't have one of those handy to try out
{:<(.
I did try some ordinary TCP (and some specially
formulate TCP) used to remove/minimize lead deposits in air cooled aircraft
engines. That did not work either, it appears that the for the chemical
reaction to be effective - it needs the higher temperatures encountered with
air-cooled cylinder heads - the relative cooler rotary apparently just doesn't
get the metal and spark plug hot enough, long enough - (at least that's my
theory).

I wonder id SAG effected spark plugs could be
chemically treated to remove deposits on the ceramic?
When I was in to
shooting at Dept of Civial Marksmanship matches, we used some liquid products
to remove lead and or copper fouling from the barrel, some were for scrubbing,
some for soaking.
Perhaps soaking the ends of the old plugs in bore cleaner
or something? bleach? Carb cleaner? tomato juice? Who knows?
Just an
idea.
