Everybody, how do you clean your Spark Plugs ?

[cbRider]

I have a collection of plugs laying on my work bench that are not worn, just fowled.
I wonder how everybody is cleaning their plus.

( I have edited the heading to get more input)

I just use a wire brush, dremel style and clean it up, then spray with carb cleaner. Could use wd-40 too or electronic contact cleaner for the spray.
