PROBLEM TO BE SOLVED: To provide a detergent composition which can clean both liquid crystal dirt and a cutting scrap such as polyimide (a foreign substance on a terminal) at the same time, and has good liquid stability; and to provide a method for cleaning a liquid crystal panel using the same. SOLUTION: The detergent composition used for cleaning a liquid crystal panel includes (A) an organic alkali, (B) a hydrocarbon, and (C) a surfactant selected from a group consisting of a polyoxyalkylene alkyl ether and a sulfosuccinic acid-type anionic surfactant, and has pH of ≥8.5.
