The invention provides environment-friendly interior cleaning fluid and a preparation method and using method thereof. The environment-friendly interior cleaning fluid is prepared from the componentsin parts by weight: 8-12 parts of an anionic surfactant, 4-8 parts of a
nonionic surfactant, 1-3 parts of a cationic surfactant, 2-5 parts of an oxidization bactericide, 0.1-1 part of a
silicone emulsion, 0.1-1 part of an
active enzyme, and 70-85 parts of deionized water. The environment-friendly interior cleaning fluid is mild and does not hurt hands, further has strong bactericidal and bacteriostatic functions besides the ability to quickly remove
dirt of vehicle interiors, 99% of
escherichia coli,
staphylococcus aureus and the like can be completely killed, mouldproof and mothproof effectsare achieved, the effects of sterilization and bacteriostasis on bacterium breeding are achieved, the foreign
