Its not worth cleaning an old MODERN plug as its insulator is porous, an old OLD plug is something different as it has a glazed insulator which is non porous and will clean. Find some really old plugs and put them in a safe place ,you may need them someday.

After years of difficult starting using NGK plugs I read a piece on the Green Plug company's web site that stated that the modern insulaters are porous and don't like to be flooded with petrol.
I sent off for some pink Lodge plugs ( apparently race plugs) and the bikes now start remarkably easily.
