Full Text	Field of Invention The present invention relates a novel cleaning composition. More particularly the invention pertains to a novel cleaning composition for cleaning metal parts. This cleaning composition finds extensive application in the industry. Background Art The present invention relates to the preparation of surfaces of metal parts for operations such as plating, painting, rust-proofing. Metal parts, during the course of manufacture, become coated with cutting oils, drawing and buffing compounds, lapping compounds, other mineral oils, dust carbon smut, chips and other materials which must be removed before inspection. It is to be noted that requirements preferred by the industry as regards to cleaning composition are as follows. a) To perform the cleaning at ambient temperatures, to save energy. b) The formulation should be user friendly. c) The formulation should preferably be without a flash point. In other words it should not be inflammable. d) The Formulations should preferably not create any environmental/effluent problem. e) After removal of the soils, the formulations should preferably provide a surface, which will resist oxidation/corrosion in the interval between operations and in some instances a storage interval. f) The formulation should provide a chemically clean surface after removal of the soils. g) The bath in which the formulation is used should have a long life for reasons of economy. h) The bath should be easy to control by the operator. The following description traces various cleaning composition known in the art and the deficiencies of the said known cleaning composition. It is to be further noted that important methods of metal cleaning are as follows. 1) Treatment with liquid solvent by spraying, dipping or hand-scrubbing. Steel parts cleaned in this way tend to rust rapidly and the surfaces are not chemically clean. 2) Vapour degreasing involves condensation of solvent vapours upon the surface of the metal. The condensed solvent drips back into the bath. The drawbacks mentioned in (1) above apply to this method also. In addition solid soil is often left back as a residue on the metal, which must be hand-wiped. 3) Alkali solution cleaning - This involves soaking of metal parts in an alkali bath with or without water soluble detergents. Spray machines may also be used. For rapid cleaning high pH values are used and high temperatures are very necessary, as the efficiency of an alkaline bath at room temperature for industrial cleaning, is practically zero. This leads to hazards to operating personnel and to danger of metal surfaces being attacked. Contamination builds up rapidly in the bath, resulting in re-deposition of the soil. Lastly it is difficult to remove last traces of alkali from metal surfaces, as they rinse very poorly, and this can increase susceptibility to corrosion. 4) Emulsion Cleaning - where the metal is treated with a soap or other emulsifying agents in an organic solvent. The emulsifying agents may aid in loosening the soil and to disperse or solubilise the soil. The metal parts are then rinsed with water and generally a pressure stream is used. High temperatures are involved. The efficiency of the process is very poor on account of poor de-wetting, rinsability, other hazards mentioned in (3) above apply. 5) Mechanical abrasion - which follows generally after removal of oil and grease. 6) Electrocleaning - The metal is made the anode or cathode in an electrolytic bath, or the polarity is periodically reversed. 7) Pickling - Acid treatment to remove surface oxide films, after removal of oil and grease. Deficiency of General Methods of Cleaning The general methods of the cleaning given above do not meet industrial requirements, and the need arose therefore, of developing a new formulation to address the needs the needs of the industry. The primary object of the invention is to develop a new cleaning composition to meet the requirement of industry. It is another object of the invention to develop a new cleaning composition which is unique. Further objects of the invention will be clear from the following description. The invention will be clearly and particularly described in the following complete specification. The nature of the invention and the manner in which it is to be performed will be clearly described in the complete specification. Development of a new Formulation to meet Industrial Needs A novel formulation, has been developed which meets all the above requirements of the industry. Summary of Invention A cleaning composition consist of the following of ingredient in the proportion mentioned herein. Ingredient Proportion a. Terpene 10%-20% b. Solvent 75% - 80% c.

Anionic group 8% -10% Method of Cleaning using this novel cleaning composition The articles to be cleaned are simply immersed in this novel cleaning composition solution at ambient for a few minutes. Spraying, agitation by circulation of novel cleaning composition, dunking, are essential for effective cleaning. Best results, however, for smaller components, are obtained with ultrasonic cleaning. Approximately three minutes in an ultrasonic bath are required for cleaning the metal of stubborn soils.
