what do you use to clean your spark plugs?
 

some dust on my plugs, maybe running rich may need cleaning, any products out there? thanks guys/gals!

new pluugs are too cheap for me too clean dirty ones.

My dad has this cast thing that has a small bag of sand on the front. You hook an air line to it, stick the plug in and push a button. It sandblasts the end of the plug. They come out sparkling clean. Then, regap and reinstall.

Lately, I just change them out and toss the old ones. For a buck or two a plug, they aren't really worth messing with. Mostly, by the time I get around to changing them, the electrode is erroded enough it's time for new anyway.

I used to think that hitting the electrodes with sandpaper = basically a new plug but I've been messing with some small engines lately and there's definitely no replacement for actual NEW plugs, plus like everybody else said - they're cheap

New plugs. Otherwise I hit them with a wire brush and brake cleaner.

You've got to watch those plug sand-blasters. The sand can lodge between the insulator and steel casing only to come out later and destroy your rings.

It's probably better to use something softer and safer for internal engine parts than sand, like crushed walnut shells.

uhhh the platinum plugs dont have very much platinum on them. sand-anything would probably take it all off fast. soak em in gasoline and compressed air them dry. face it, if explosions dont clean them, it's pointless to do it yourself.

NGKs are only $2 a plug, why even try to clean them?

sulfuric acid eh? i'm sure that cleans em and takes a lil more away too lol

EDIT: no i didnt google...i just remembered the poem.

But Johnny is no more.
What Johnny thought was H20
was H2SO4.
