Cleaner composition
A cleaner composition includes: a saturated aliphatic hydrocarbon (A); an anionic surfactant (B); a nonionic surfactant (C); and water (D). The cleaner composition contains the saturated aliphatic hydrocarbon (A) in a proportion of 60.0% by mass to 85.0% by mass, the anionic surfactant (B) in a proportion of 8.0% by mass to 15.0% by mass, the nonionic surfactant (C) in a proportion of 2.0% by mass to 5.0% by mass, and the water (D) in a proportion of 1.0% by mass to 20.0% by mass, forms a W/O microemulsion or a solubilized W/O emulsion, and has a volume resistivity of 1×10 9 Ω·cm or less.
