After the repair, just clean that one plug... I've used an old tootbrush and gasoline. After it's sparking again it'll burn off the rest of the residue.

Nissan expressly warns against using cleaned plugs in the FSM, but Heath's method should be fine. No abrasives, stiff metal brushes, nor caustic or acidic cleaners should be used.

True for any Plat/Iridium plug. No sense spending all that money if you end up scraping the coating off.
