An oil-pump-screen (1) cleaning method and apparatus with which an oil pan (3) of an internal-combustion engine (2) is drained by removal of a drain plug (7) from a drain aperture (15); the drain plug is reinserted in the drain aperture; a measured amount of a predetermined carbon-disintegrative liquid is put in the oil pan, preferably through a dipstick tube (10), to immerse the oil-pump pickup screen, but not the oil pump (41) without contacting engine bearings, gaskets, or other engine components that could be deteriorated or otherwise damaged by the carbon-disintegrative liquid. The cleaner liquid is left in the oil pan long enough, preferably about one hour, for it to disintegrate and dislodge all carbonic and other material from the oil-pump pickup screen while not running the engine or otherwise conveying the carbon-disintegrative liquid to other parts of the engine. The oil pan is drained to remove the cleaner liquid, the drain plug is replaced and flush liquid is put into the oil pan where it is left for about forty-five minutes. The oil pan is then drained and filled with new engine oil or other liquid lubricant. A clean-run oil filter (5), which can be the old oil filter, is left in or put into the oil-filter cannister (6) while the engine is run for about two-to-ten minutes. Then, the oil filter is replaced with a new one and the oil level is adjusted to complete the method.
