Castrol Techniclean™ MP is an aqueous, alkaline industrial multi-purpose cleaner containing biodegradable surfactants and corrosion inhibitors. Techniclean MP is a multi-purpose process cleaner for precision cleaning of ferrous metals to the most demanding specifications in a wide range of modern equipment, which includes spray and flood wash as well as all types of dip and ultrasonic applications. Techniclean MP may be used on aluminium with caution: test a sample first to ensure no staining or corrosion, as temperature, concentration and exposure time are all important. Techniclean MP effectively removes soluble oils, light-medium duty neat cutting or forming oils, lubrication oils, soft film corrosion preventives, swarf and general dirt.
