Process                     	:	An Aqueous Cleaning Solution for Removing Oil and Grease from Steel Components.2. Application	:	The degreasing solution can be used for removing oil and grease from steel and non-ferrous components and automobile bodies. 3. Advantages	: 	1. The solution could be applied over the components using cotton pads or by dipping the components in the solution for removal of oil and grease.	2. The solution could be used for removing oil and grease at room temperature and also by compressed air spray.	3. The prepared aqueous solution is cost effective compared to the existing systems.	4. The process as whole is materials friendly , since the solution is alkaline and hence there is no metal loss.	5.The process as a whole is user friendly as there is no hazard in the present system compared to the existing system.	6.The process material is easy to transport, since it is in solid form. It can be dissolved in water at the time of application.4. CECRI Process: Detailed descriptionof the process		The process consists of mixing of an alkali metal salts in water with additives, surfactant and chelating agent to get the oil and grease remover formulation in solution form. This formulation can be applied over oil and grease adherent on ferrous and nonferrous components which would remove them instantaneously.5. Other feature of this process	:                        a)  This degreasing solution is tested as per the IS 3194 – 1980   and found that this degreasing solution is effectively worked out.	                                                                            b) There is no skin irritation while working.  Eventhough the workers are advisable to use hand gloves.	                                                             6. Present demand	:	 500 tonnes /year7. Scale of investigation	:	 25 litres.8.
