METKLEEN 2100 is a high alkaline, aqueous cleaner with a built in rust preventative for extremely tough soils and heavy-duty cleaning jobs. METKLEEN 2100 is designed specifically for hot tank and spray cleaning but can be adapted to other cleaning processes. The high alkalinity formulation includes an inhibitor that allows METKLEEN 2100 to clean aluminum without attacking the metal. METKLEEN 2100 is the ideal choice for mixed metal cleaning operations.
