At the start of the project halogenated hydrocarbons (HHC) were used on a large scale for cleaning parts in the electrical industry to meet the high requirements of manufacturing. However, the use of these chemicals causes a serious danger to the environment. The aim of the project was the development of non polluting cleaning processes to reduce the consumption of HHC and also the environmental pollution without a deterioration of the surface state quality and production safety. As an alternative mainly processes with aqueous media come into consideration. Therefore tests samples have been cleaned with several media under practical conditions and the properties of the cleaned surfaces determined by visual inspection and surface analytics. ...
