Hi Jeff,
Thanks for the suggestion, I actually did some
research into the products used by shooters to clean fouling in their
barrels. It appears that the lead left in a gun barrel is metallic lead
(naturally) whereas the lead on the ceramic appears to be a lead nitrate
crystal. I actually started down that path, but when the wife came back
with the lead cleaning product from one of her shopping trips, it turned out to
be the wrong stuff. So, I shouldn't write it off as I have not actually
tried it.
Perhaps that will be experiment #2 - I'll throw the
ultrasound in just for luck. I mean what the heck, this is all about
experimentation, right?

Getting around to see what can be done about the lead
fouling sparkplugs causing the infamous "SAG". 1st experiment
was to place the used spark plugs in a 30% solution of Hydrogen
Peroxide. I did that and place the plugs and solution in an ultrasonic
cleaner, turned it on and left it on for 1 hour.
It appeared to clean everything off the plug - but,
the lead. So far the only chemical my research has indicated would
dissolved metallic lead is Nitric Acid. Nope, not going to try that,
I'll stick with buying new plugs.
But, thought I would let folks know of the
results. I was really hoping the ultrasonic vibration would shake the
lead crystals off the ceramic cone of the plug - but either the idea is
flawed or the small jewelry cleaning size ultrasonic generator is simply not
powerful enough.
