METAPREP : HSC (Multipurpose Alkaline Heavy Soak Cleaner)

Ronuk Metaprep H.S.C. is a high – efficiency, multipurpose alkaline heavy duty soak cleaner designed for use wherever a large variety of SOILS on metals must be processed. Oils, greases, waxy drawing compounds, buffing residues, sulphurized and chlorinated oils, and emulsion cleaner films are easily penetrated, softened and removed. The activity of the cleaners is accelerated with the use of air, mechanical or ultrasonic agitation. It has particularly good penetrating powers and is therefore suitable for tubular wire work.
