Two liquid cleaners developed by Birchwood Technologies can be used on a wide variety of process lines, including blackening, phosphating or electroplating lines. Safe Scrub® M and Safe Scrub® ST cleaners easily remove oil and surface soils on metal parts. These cleaners are effective biodegradable solutions that can be used on metal parts before or after processing.

Safe Scrub® M and Safe Scrub® ST are used to emulsify oil from aluminum, brass, copper, iron, and steel parts, and then hold residues in the solution to prevent them from re-depositing on the parts. Both cleaners effectively remove these types of fluids: mineral oil, grinding coolant, drawing/stamping lubes, and hydraulic oils, as well as water soluble/synthetic fluids. These products can be used as stand-alone cleaners after metalworking operations or as a pre-cleaner prior to metal finishing operations

SAFE SCRUB M is a non-caustic, mildly alkaline cleaner for use on aluminum, brass and copper components. Its mild formula cleans thoroughly without oxidizing or discoloring the substrate.

SAFE SCRUB ST is a heavy-duty liquid cleaner for use on iron and steel components. It has high oil-holding capacity and stability at high temperatures for super heavy-duty applications. 

Safe Scrub® M and Safe Scrub® ST are environmentally friendly choices because they contain biodegradable surfactants and no chelating agents, which allows for easy disposal. They are supplied as concentrates that dissolve instantly in water to make the operating bath, and are then heated to 130-170°F operating temperature. When the solutions are allowed to cool, much of the emulsified oil will float to the surface, allowing removal of the oil with an oil skimmer or coalescing filter and maximizing the working life of the Safe Scrub® M and Safe Scrub® ST cleaning solutions.

In general, liquid cleaners dissolve instantly and are easier and safer to utilize than powdered products, and are also more free-rinsing. They give the ability to produce clean surfaces that are receptive to subsequent coating and finishing operations.
