Abstract
The invention provides a substrate detergent composition used for cleaning a surface of a substrate, comprising: (A) A quaternary ammonium salt: 0.1 to 2.0% by mass; (B) Water: 0.1 to 4.0% by mass; and (C) An organic solvent: 94.0 to 99.8% by mass. There can be provided a substrate detergent composition used for cleaning a surface of a substrate contaminated with a silicone component whose water contact angle is 100° or more.
