General Spark Plug Question
#1
Does cleaning spark plugs with a wire brush ruin the plugs? Does it cause electrical shorts on the plug? What about the sand blasting bag things that i've seen in mechanic shops? Do they cause electrical shorts too? Discuss

Lets assume the plugs are brand new and got carbon fouled and just need a good cleaning. I agree if the plugs are old its just time to change them.
