PURPOSE: Provided is a method for removing engine deposits in a reciprocating internal combustion engine, which is effective in cleaning various types of engine using gasoline, diesel and natural gas, without disassembly of engine. CONSTITUTION: The method for removing engine deposits in a reciprocating internal combustion engine comprises infusing a cleaning composition into an air-intake manifold of a pre-warmed and idling engine and operating the engine while infusing the cleaning composition. The cleaning composition used in such method comprises a first solution containing a mixture of (a) a phenoxy mono- or poly(oxyalkylene) alcohol, or a mixture thereof, (b) at least one solvent selected from (1) an aliphatic alcohol and (2) an aliphatic or aromatic organic solvent, and (c) at least one nitrogen-containing detergent additive; and a second solution containing a mixture of (d) a phenoxy mono- or poly(oxyalkylene) alcohol, or a mixture thereof, (e) a cyclic carbonate, and (f) water.
