cleaning spark plugs

When I was a kid my dad and I always used to usually clean the spark plugs rather than replace them. Used a small wire brush to give them a good scrub, a bit of fine folded sand paper to clean between the contacts and then had a feeler gauge (same tool used to set tappet clearance) to set the gap.

removed my old iridiums as the car was running lean and they were black when removed...they had only covered 5k miles

 

Is there anyway I can clean them to reuse if I need to?

 

Not running lean then. Lean would cause a white/grey colour on the ceramic/tip.

You need a proper grit blast plug cleaner. If you want you can post them to me and I can blast them and return them, won't cost very much, say a tenner, and return insured P&P would be 5.80. DO NOT use a wire brush, the metal from the bristles fets on the ceramic and makes it conductive and you get misfiring. Was OK with old systems, but not high KV modern ones, nor fine electrode plugs!
