Oddly enough, I just cleaned my not-so-expensive plugs in my hot rod this morning. I used what Harbor Freight calls their "abrasive eraser." It's a small sandblast gun that shoots a very fine abrasive. With that and soaking them in lacquer thinner, they looked new. Harbor Freight also sells a small spark plug cleaner that is along the lines of those used at garages 50 years ago. I don't have one of those, so I don't know how well it works. But the porcelain is bright and white again.
I've had a spark plugs cleaner for some 30 years. After 25 years I finally had to buy new set of plugs.. simple tool as other wrote here. It's a plug blaster.. very inexpensive these days used with a household air compressor. Basically, sand blaster..
Personally I prefer soaking the plugs in vinegar for a day or two. Its amazing how it softens up the carbon. I use a wire brush working the bristles down the barrel. Then I burn the remainder off with a torch. It still leaves the insulator dark in colour. I have to wonder how much this affects performance. Just like new? Maybe not but it does extend the life in my experience.
The goal of my channel is not only to save money, but also to reduce our carbon footprint. I dislike the fact that we are helping the potential enemy build their war machine with our discards.

Dont want to buy one. I have a Burnzo matic on hand, cost- zero. And , no risk of introducing Abrasives to the engine.

Good tip, some of those old plugs are definitely expensive to replace.
Clean rust off metal
You buy yourself a sparkplug cleaner, it's a mini sandblaster, works great, end of story.
Burning off the carbon is fine on non resistor plugs but plugs with resistors might melt or damage the resistor.
Great tip thanks
thank you
I used a spark plug sand blaster
Put new ones in

Use sand paper
Cant get sandpaper around the electrode.
Never liked Boshe spark plugs
I usually w eighteen champions. Or AC plugs.
