Spark Plug Cleaners

[michael.konor]

Anyone using a pneumatic spark plug cleaner? If so, results and recommendations?

My main concern with the cheap models causing some of silica compound to embed between the electrode and metal, dislodging, and then scoring a cylinder.

Saw one for the first time last night, Will Not Use!
As you said, the silica can get lodged and fall out later.
