Safe Scrub® OS split cleaner is designed for use in heavy-duty cleaning applications to remove oils and surface soils that are difficult to emulsify. It effectively lifts oil from iron and steel parts, then floats the oil residue to the liquid surface for removal from the tank by an oil skimmer or coalescing filter, thereby maximizing the working life of the cleaning solution. The cleaner effectively removes mineral oil grinding coolants, drawing and stamping lubes, hydraulic oils as well as water soluble/synthetic fluids. It can be used as a stand-alone cleaner after metalworking operations, or as a precleaner to black oxide coating. Supplied as a liquid concentrate, it contains biodegradable surfactants, mixes instantly with water and contains no EPA regulated metals. The normal cleaning cycle calls for 5-10 minute soak at 120-150°F.
