Safe Scrub ST from Birchwood Technologies is specifically formulated to remove oil and surface soils on metals prior to finishing. The biodegradable liquid cleaner emulsifies the oil from iron and steel parts, and then holds the oil residues in solution to prevent them from re-depositing on the parts. Designed for medium to heavy-duty soak tank cleaning, Safe Scrub ST mixes easily with water and operates at temperatures of 120 to 180°F. When the solution is allowed to cool, much of the emulsified oil will float to the surface, enabling removal with an oil skimmer or coalescing filter. The cleaner is free-rinsing in cold water, providing waterbreak-free surfaces that are receptive to subsequent coating and finishing operations.
Safe Scrub ST can effectively remove mineral oil, grinding coolant, drawing/stamping lubes and hydraulic oils, as well as water-soluble/synthetic fluids. It can be used as stand-alone cleaner after metalworking operations or as a pre-cleaner prior to finishing operations such as black oxide coating or phosphating.
