To obtain a detergent composition exhibiting high detergency on hard surfaces such as automotive coated surfaces and capable of forming a protective film with excellent antifouling effect on a hard surface after washed.

This detergent composition with antifouling performance for hard surfaces comprises at least one detergent component selected from amphoteric surfactant, anionic surfactant, nonionic surfactant, sequestering agent and water-miscible solvent, a film-forming substance capable of forming a hydrophilic protective film on a hard surface through application thereto together with the detergent component, and a binder component for improving the adhesion of the protective film formed by the film-forming substance.
