Thanks for the report, Dale.  You make a good point about degree of adherence.  I am uncertain the mechanism of the lead crystals attaching to the ceramic cone.  But, the wife came back with Hoppe #9 and when I looked at the ingridents on the lable - there was only one - Kerosene!

If that is all it contains then that tells me is a mild cleaner and lubricant but not a solvent of lead

Many mild cleaners that are designed to be used repetively work in two ways.  First, they assist is removing whatever needs to be removed. Second, they lay down a layer that will make it harder for whatever to stick, making it easier to clean the second time.

Would it be possible to coat the plug tips ceramic area such that the lead will have a harder time getting hold in the first place?  I'm thinking that maybe one of the super slick dry lubricants that are backed on might do the trick.
