A detergent composition for precision parts or jigs includes (a) a hydrocarbon having a 10-18 carbon atoms,, (b) polyalkylene glycol C1-C3 alkyl ether, and (c) a polyalkylene glycol C4-C8 alkyl ether, wherein a weight ratio of component (a) to the sum of components (b) and (c), (a)/[(b)+(c)], is fro
A detergent composition for precision parts or jigs includes (a) a hydrocarbon having a 10-18 carbon atoms,, (b) polyalkylene glycol C1-C3 alkyl ether, and (c) a polyalkylene glycol C4-C8 alkyl ether, wherein a weight ratio of component (a) to the sum of components (b) and (c), (a)/[(b)+(c)], is from 5/95 to 95/5, and a weight ratio of component (b) to component (c), (b)/(c), is from 5/95 to 95/5. The composition is excellent in removing smears such as fats and/or oils, machine oils, cutting oils, greases, liquid crystals, and/or rosin fluxes which have adhered to surfaces of precision parts or jigs. The present composition also exhibits excellent rinsability and high safety and is free of any fear of environmental pollution.
