Zusammenfassung:The invention relates to amino acid composite acid cleaning inhibiter and an application method thereof. The inhibiter consists of amino acid, iodized salt and hexadecyl trimethyl ammonium bromide, and the mixing ratio of the three components is 1-5: 1-5: 1-5; the inhibiter is used for industrial acid cleaning together with acid pickling solution, and the application method is as follows: the acid pickling solution is dilute sulphuric acid or dilute hydrochloric acid with 0.1m to 2m of concentration, the weight content of the inhibiter in the acid pickling solution is 0.001g/l to 2.0g/l, the acid cleaning temperature is 20 DEG C to 60 DEG C, and the acid cleaning time is 0.5h to 6h. The invention is mixed inhibiter with amino acid as the main component; amino acid can be well dissolved in water, has no toxin and harm to the environment, is capable of biodegradation, has high restraining efficiency, strong continuity capability and is very potential green inhibiter; in addition, the inhibiter has high efficien
