What Is Semi-Aqueous Cleaning?
The semi-aqueous cleaning process incorporates an organic medium to clean components and then water as the rinse medium. It, theoretically, utilises the specific cleaning benefits of both solvent and aqueous cleaning to effectively remove both organic and inorganic contaminants. The organic wash solution becomes progressively contaminated with use and so must be periodically replaced with fresh solution. The rinse water is also continuously purified to remove the organic component.
The cleaning process normally utilises liquid immersion cleaning with either spray under immersion or ultrasonic agitation.
