<P>PROBLEM TO BE SOLVED: To provide a deposit cleaner capable of efficiently cleaning deposit containing water-soluble components such as sulfates. <P>SOLUTION: An injector deposit containing water-soluble components such as sulfates is effectively cleaned by that a deposit cleaner containing a nonionic surfactant having an HLB of 2.8-18.2 such as polyoxyethylene synthetic alcohol ether and an anionic surfactant such as sodium dioctylsulfosuccinate is used by adding the deposit cleaner into gasoline in an amount to get the nonionic surfactant concentration of 100-10,000 ppm and the anionic surfactant concentration of 100-10,000 ppm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
