Abstract
The present invention relates to a agent for cleaning metal drawing oil, which contains alcohol, glycol ether, water, and one or more compounds selected from hydrocarbon or ester compounds. The cleaning agent according to the present invention is environmentally friendly because it does not contain halogen elements such as chlorine. The agent can reduce toxicity on the human body due to low volatility; is economical due to the long change period resulting from the reduction of evaporation; and removes drawing oil having high viscosity and polarity effectively during metal processing.
