Just got all the supplies for doing my own spark plug rotation and cleanings. Being I fly about 150 hours a year, just makes sense to do myself. Bought all the goodies that I didn't already have, the right socket, gaskets, rack, Anti-sieze, gapper guage and tool, etc and the $39.99 vibrating or ultrasonic cleaner from Spruce, but also noticed they sold a blaster unit for cleaning, some of the comments was it was really just a HF one. So I stopped by and grabbed one at HF today and then got reading up on the cleaning process.... Looks like blasting them is not a unversally accepted thing to do... What do you guys n gals do with cleaning them and why? I see the disadvantage of blasting is wear, whats the upside of blasting it instead of just the vibrating cleaner?
