Originally titled 'Liquid Cleaner Removes Soils from Metals Prior to Finishing'
Safe Scrub ST liquid cleaner from Birchwood Technologies is formulated to remove oil and surface soils on metals prior to finishing. The biodegradable cleaner emulsifies 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 from 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. It then rinses free in cold water, giving it the ability to produce waterbreak-free surfaces that are receptive to subsequent coating and finishing operations.
Safe Scrub ST effectively removes 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 metal finishing operations such as black oxide coating or phosphating.
