Sooo... sandblasting with fine grain garnet or aluminum oxide media has always been used to remove lead fouling from sparkplug ceramic insulators, eh? And... not just with Champion sparkplugs, huh? Well, feature that.

Yes but it won't get the stuff that is built up in the deep in the recess between in the insulator and the outer portion of the plug on an aircraft plug. I would call it more of a finishing touch on the electrode. Hard to see how it would get into the recess on a 13B spark plug.
