Metal corrosion product cleaning agent and use method thereof

The invention discloses a metal corrosion product cleaning agent and a usage thereof. The cleaning agent is an aqueous solution consisting of a complexing agent, an auxiliary agent and water. The cleaning agent is characterized in that the aqueous solution contains EDTA disodium salt which accounts for 10 to 15 percent of weight and is used as the complexing agent, hydrazine which accounts for 1 percent of weight and is used as the auxiliary agent, as well as the balance being water. In the usage of the cleaning agent, when the cleaning agent is used to clean metal corrosion products, the temperature of the cleaning agent needs to be kept between 90 and 100 DEG C. The cleaning agent has the prominent advantages that the cleaning agent improves the efficiency and effect of cleaning metal corrosion product mixture Fe3O4+Fe(OH)3 and is little corrosion on equipment material, economical and applicable.
