Spark plug cleaner?

My PA50 shop manual features a graphic of a air-blasting spark plug cleaner.

I have read that the standard grit in these cleaners will abrade the ceramic surface of spark plugs and that glass beads should be used instead.

Question: Is it worth the investment of about $15...plus the cost of glass beads...in such a device?

I wonder how often a plug may be reconditioned before the ends of the electrodes are rounded off and the plug must be discarded?

In my area, a moped plug costs no more than two bucks. I haven't run a 'ped long enough to amortize the investment in such a cleaner.

Is anyone out there using such a machine? I would be interested in their comments.

Many years ago we used a sand blaster but they fell out of use because plugs were cheap. Your moped has one plug and when it dies you pedal. Think about it. Jim.

Carb spray works pretty well for me.

for only $1.50, why waste your time cleaning a plug that has a worn or pitted electrode?

Re: Spark plug cleaner?

The concept is to remove carbon deposits and renew the plug <until> such time as the electrodes become pitted or rounded.

It would depend upon how soon such deposits accumulate on a particular bike and how they affect performance.

Emery (Plumber's cloth) abrasive and carb spray seem a good way to go.

I can't imagine why Honda featured that plug blaster in their published shop manual. Perhaps plugs were comparatively expensive thirty years ago.
