<p>This invention relates to a method of cleaning electronic components using a water-miscible solvent system. In the method, the components are washed with a water-miscible solvent system, rinsed with water and the used solvent and water entraining the impurities are combined and passed through an absorptive medium which retains all the suspended impurities but does not absorb the solvent or water. The cleaned aqueous solvent can be recovered and concentrated by evaporating off the water to leave behing a concentrated solvent solution. Use of this method minimises emission of undesirable inorganic, organic and/or particulate materials into the environment.</p> |
