[0002] While the cement industry is booming, its environmental load is also increasing, except for some well-known environmental problems such as CO 2 In addition to emissions and dust pollution, there are still some problems that are easily overlooked by people. The specific manifestations are: 1) In industrial production, excess hardened cement is attached to pipelines and equipment, causing equipment to stop; a large amount of cement clinker produced by cement factories Dust accumulates on the roof and will condense and harden for a long time, increasing the safety hazard of the building
2) In life, the cement will pollute the environment after it solidifies, and the cement stains attached to daily necessities are difficult to remove, all of which affect people's quality of life
3) In scientific research, cement solidification and hardening in machines and instruments will affect the life of the equipment and even damage the equipment
It is very difficult to clean the dirt of cement hardened body, which is determined by its characteristics: 1) Cement is a kind of hydraulic cementitious material. If you use tools to forcibly remove the dirt layer, it will damage the original surface of the object

Abstract
The invention belongs to the technical field of chemical cleaning, and particularly relates to a hardened cement body dirt cleaning agent and a usage method thereof. The cleaning agent comprises raw materials as follows: water, glycolic acid, oxalic acid, a surfactant, a corrosion inhibitor, a penetrating agent, a scaling inhibitor, a rust inhibitor, a coloring agent and a thickening agent. The cleaning agent is sprayed onto thin-layer hardened cement body dirt and can quickly penetrate into the hardened cement body dirt to have chemical reactions and form fluffy substances, the cementing force of cement is decreased, and the hardened cement body dirt can be easily removed when washed with clear water after a period of time. The cleaning agent has the outstanding characteristics that the cleaning agent is non-toxic, harmless, capable of avoiding corrosion to base body materials such as metal equipment and the like, low in harm to operators and the like, can be widely applied to cleaning of house wall surface cement dirt, hardened cement body dirt on experimental equipment or cement stains on articles for daily use and the like, and has good economic benefit and environmental benefit.
