PURPOSE: A cleaning composition is provided to eliminate scales and rusts attached to the metallic industrial apparatus and component, and eliminate organic oil at the same time. CONSTITUTION: A manufacturing method of a cleaning composition comprises: a step of obtaining solution containing succinic acid, L-tartaric acid, and sodium gluconate; a step of neutralizing the solution by trisodium phosphate; and a step of obtaining the cleaning composition by adding surfactant to the neutralized solution. The surfactant is sodium lauryl sulfate and has 0.1-2.0wt% comparison to the cleaning composition. In the step of neutralizing, the weight ratio of succinic acid, L-tartaric acid and sodium gluconate, and trisodium phosphate is 50:1-20. |
