Humm, pressure washing???? Just popped into my
head - I wonder??
Naturally, I would like a simply, straight forward,
non-hazardous, inexpensive and effective method - oh, yes, and one that does
not involved a lot of work {:>)

Years ago, you could take your plugs to any filling station, and use the
official Champion plug cleaner. A blue/grey box with a rubber cover that had a
hole in it to insert the plug.
You pushed a button and wiggled the plug around a bit, and the plug came
out like new.
I don't know if it was done with glass beads, or walnut hulls, or
sand.
Along side this box, was another that had a glass window in so when you
screwed the cleaned plug in the box, you could see the end of it through the
window.
You connected the high voltage lead and opened a valve to increase air
pressure in the box.
The plug would keep arcing right up to full line pressure, where a dirty
plug would not.
No longer available because "A" few people know what a spark plug is, and
"B" Lawyers.
