About AquaKlean® STC

AquaKlean® STC is a highly alkaline, ultra-heavy-duty liquid cleaner engineered for demanding ferrous-metal and stainless-steel cleaning. Its non-silicated chemistry removes grease, oils, chlorinated oils, fingerprints, inks, drawing compounds, metalworking fluids, polishing and buffing compounds, and difficult carbonaceous deposits.

AquaKlean® STC combines high soil-loading capacity with unusually fast and complete rinsing. Its lower conductivity compared with conventional highly alkaline cleaners helps reduce rinse requirements, while low-foam performance makes it well suited for spray washers, agitated tanks and production cleaning systems. Above 110°F, AquaKlean® STC operates essentially foam-free.

Designed specifically for ferrous metals and stainless steel, AquaKlean® STC can be used from ambient temperature through high-temperature processing. It is also suitable for cast iron and magnesium, but should not be used on aluminum, copper, zinc, lead, tin or their alloys.
