Ed,

Lye is sodium hydroxide and the closest place to buy it is your hardware or grocery store: Drano.

Boy, that might do the job, Ok.  I remember mother used to make Lye soap with Hog fat - that would take paint off cars, skin off people, etc.  Just might do the job.  Use to be able to get it a plumbing stores - but, doubt they carry it anymore - too corrosive.

Ed,
I've been trying to remember what my dad told me they used to use to
clean their spark plugs.  Finally, I remembered... it was lye.  I never
tried it myself, but it could be worth a try.  Don't know where to go to
buy it though.

Hey Ed,

I like the Coke idea!!
There is a list out there with "1001 uses for Coke!", the last is " You
also
can trink it!!" :))

Googling around on "Acetone lead remover", I found this:

_______________________________________________________________

Lead Removal

For really stubborn lead removal try a 50/50 mix of  3% Hydrogen
Peroxide
(the common drug store variety) and white vinegar.  Plug the bore, fill
it
up using a dropper or syringe and let it stand for 5-10 minutes.  (Do
not
let it stand for too long.) You may get some foaming so protect the
barrel's
external finish as this solution is not kind to bluing--so take
appropriate
precautions. Drain and wipe out the black muck that used to be lead and
then
immediately clean well with bore cleaner.

Thanks to Joe Sledge for this recipe.

Pure turpentine has reportedly also been used as a lead remover.

Also, as Acetone is the prime solvent in lots of paint
removers/cleaners/etc. you might want to experiment with Acetone.

I think someone in our hangar mentioned a mix of Acetone and Hydrogen
Peroxide, but I am not sure wether this possible/makes any sense/is
hear-say/or what - don't blow up your new hangar trying
plug-cleaner-witchcraft!!

I have no idea about the cleaners vs solvents (how does it clean it if
it doesn't dissolve it?), but I've been thinking.  The electrodes

should

be made of a fairly corrosive resistent material.  Couldn't they
withstand a short bath in a mild acid...maybe a little vinegar or a

warm

Coke?  The burnt lead should react quickly.
