The invention discloses a chemical stainless steel cleaner and a preparation method thereof, belongs to the technical field of chemical cleaning, and particularly relates to the technical field of stainless steel cleaning in order to solve the problem of the risk of secondary corrosion to stainless steel due to strong alkalinity of the existing cleaner. The chemical stainless steel cleaner contains a surfactant, citric acid, oxalic acid, tartaric acid, allicin, ethanol, a defoamer, a corrosion inhibitor, sodium molybdate, triethanolamine and water, wherein the surfactant has a degreasing effect and removes grease on the surface of the stainless steel, the citric acid not only can prolong the service life of the cleaner, but also can have a smell masking function through repeated use, and the oxalic acid not only can prolong the service life of the cleaner, but also can precipitate iron ions; and the surfactant, ethanol, acid, sodium molybdate and triethanolamine are used to remove oxide and greasy dirt on the
