The invention discloses a method for cleaning a monocrystalline silicon chip, and aims to provide a method for cleaning the monocrystalline silicon chip. Residues of white spots, fingers, mortars and the like on the surface of the silicon chip are removed, and the phenomena of fingerprints and the white spots on the surface of the silicon chip are eliminated, so that the quality and the conversion efficiency of a solar-grade monocrystalline silicon chip are further improved. The method comprises the following steps: mortar pre-flushing, degumming, chip inserting, cleaning, spin drying and detection. Through the steps of the mortar pre-flushing, the degumming, the chip inserting, the cleaning, the spin drying and the detection, the method particularly adopts immersion of fluohydric acid solution and a conventionally different cleaning method, and a worker wears a corresponding glove during different process operations to clean the silicon chip through fluohydric acid immersion and cleaning solution to effectively eliminate the phenomena of the fingerprints and the white spots.
