Spark Plug Cleaning

[cobra428]

Hi Guys,
The spark plug for my H&M has gotten quite carbonized from my ign problems and playing around. So I put it in the parts washer for a little while then hit it with a light bead blast. Beautifully clean! But I noticed (under magnification) pitting from the beads. I am using fine glass beads. Now that my ign and carb problems are straighted out the plug has that nice whitish brown but will still need cleaning in the future.

Does anybody have a "magic" solution? $20 a plug....it could get expensive

Thanks
Tony

Hi Tony
I recently read in an old Popular Science Magazine that soaking spark plugs in household ammonia will remove carbon etc buildup. I suspect it would loosen carbon then it could be washed out.

Throttle body cleaner. The best throttle body cleaner I ever used was Valvoline Synpower. Unfortunately, I don't think it is available anymore. Another idea would be to soak it in a fuel system cleaner like Chevron Techtron. Either way, both are designed to remove carbon deposits.
