2. Description of the Related Art Conventionally, in the processing industry of metal parts such as the machine and automobile industries, various oils such as cutting oil, processing oil, press oil, or oil such as grease or wax are used in the manufacturing process. Many of them are used, and these are attached to various parts (objects to be washed), so that they are appropriately removed by washing. In the electric and electronic industries, a flux is applied in advance in the printed wiring board manufacturing process in order to firmly adhere the solder and the base material. If this flux remains on a printed circuit or a printed wiring board, it may cause poor conductivity or corrosion. Therefore, usually, the flux is appropriately cleaned and removed after soldering. Known techniques for cleaning these include, for example, Japanese Patent Application Laid-Open No. 2-1456.
No. 98, a chlorofluorocarbon solvent containing methyl chloroform and the like disclosed in JP-A-3-97797, or a terpene compound and a specific surfactant described in JP-A-3-13198. A water-based cleaning agent, such as an alkali cleaning, which is obtained by adding an organic salt or a surfactant to water, is also considered.

At present, with increasing awareness of social environmental problems, chlorofluorocarbon-based solvents such as chlorofluorocarbon-based solvents such as chlorofluorocarbon 113 and chlorofluorocarbons have been used worldwide as ozone depleting substances. , Because it has been agreed that its manufacture and use will be banned in the near future,
It has become necessary to radically change the cleaning agent using these solvents. In addition, a detergent containing a terpene compound and a specific surfactant has both characteristics of environmental safety and detergency. However, in the same manner as a water-based detergent, the detergent contained in the wastewater after the washing step is used. Has become an important issue. Under such circumstances, there has not yet been found a detergent capable of completely satisfying the required performances such as environmental safety, wastewater treatment properties, cleaning properties, practicality, etc. In the industrial field for cleaning printed wiring boards and the like to which the like has adhered, as soon as possible, a cleaning agent that completely satisfies the required performance has been demanded.

Means for Solving the Problems The present inventors have conducted intensive studies in view of the state of the art as described above, and as a result, have found that hydrocarbons, which are relatively inexpensive solvents that can be stably supplied industrially, have been developed.
When the ester represented by the general formula (1) is used in combination at a certain ratio, the dissolving power for stains is remarkably increased, and further, by using the surfactant represented by the general formula (2), the water is mixed with water. When the emulsion is formed, it can be separated from water in a short time after forming the emulsion, so that the solvent can be easily rinsed (water rinse) from the object to be cleaned,
It has been found that the amount of solvent contained in the wastewater after the washing step is extremely small, and the present invention has been completed.

The cleaning agent of the present invention uses a specific ester at a certain ratio to a certain ratio of saturated hydrocarbons, so that the detergent has a remarkably increased dissolving power to soil and a certain surfactant. Is used in a specific ratio to form an emulsion when the detergent is mixed with water, and can be separated from water in a short time. Therefore, according to the present invention, not only can the water from the object to be cleaned be easily rinsed with water (water rinsing), but also the effect that the amount of solvent contained in the wastewater after the cleaning step is extremely small can be obtained.
