with other detergents at all.
The common detergent is only to remove or erase the oil.

The exact application of our detergent is for dissolving oil, greasy, lubricants and other similar dirt on the surface of various implements ,such as metal ,plastic, aluminium, glass, stone, wood, ect.
At the same time the peculiar and abnormal smell will be splited out thoroughly, and not neccessory to wash with water except
