Show To Free Spark Plug of Adhering Carbon Spark plug porcelains may be freed of all carbonaceous or other foreign mattor by soaking them In a solution of carbon disulphlde, obtalnablo at nny drug store.' This solution dissolves the carbon and leaves the porcelain bright. Of course this treatment applies particularly to tho type of porcelain which Is removable from the shell of the plug, but the same method of cleaning can be used even If the plug Is of tho so-called one-piece type. Just soak the whole plug, shell and all. It won't do any harm, aud is one reasonably reason-ably effective way of attacking that carbon which resists the efforts to dig I out with a knife or other tool. ' |
