<p>Provided is a cleaning liquid composition which can clean and remove dirt which comprises lowly polar dirt and highly polar dirt and which is attached to parts used in a variety of industrial fields, such as automobiles, machinery, precision instruments, electrical parts, electronics and optics. The cleaning liquid composition of the present invention contains (A) a straight chain saturated aliphatic hydrocarbon, (B) an anionic surfactant, (C) a non-ionic surfactant and (D) water. The content of component (A) is 60.0 to 85.0 mass % relative to the cleaning liquid composition, the content of component (B) is 8.0 to 15.0 mass % relative to the cleaning liquid composition, the content of component (C) is 2.0 to 5.0 mass % relative to the cleaning liquid composition, the content of component (D) is 1.0 to 20.0 mass % relative to the cleaning liquid composition, the total content of components (B) and (C) is 10.0 to 20.0 mass % relative to the cleaning liquid composition, the content ratio of components (B) and (C) ((B) / (C)) is 2.0 to 5.0, and the saturated water content, as measured by means of the turbidity of a mixed liquid obtained by adding water to a composition comprising the components (A), (B) and (C), is 10 mass % or higher.</p> |
