Abstract
The invention provides a spark plug cleaner operating to break up fouling carbon deposit by blasting the fouled surfaces of a spark plug, with a blasting abrasive such as granular tungsten carbide, zirconium or aluminum oxide of 36 to 46 grain size to break up the encrustation of carbon deposit on those surfaces of the plug which are exposed to combustion, and in particular, to remove the carbon from the surface of the insulator of the plug which is exposed to fractional combustion of fuel and lubricating oil. The invention performs this service by producing impingement of abrasive particles comprising a granular metal carbide, such as tungsten carbide, upon the fouled surfaces. The invention may be embodied in a spark plug cleaner which will treat only a single spark plug at one cleaning operation or it may be embodied in a plug cleaning operation performed upon a plurality of plugs simultaneously, in a single spark plug cleaner.
