Dev-Kleen 3K-LF


Dev-Kleen 3K-LF is a heavy duty, potassium based liquid alkaline cleaner designed to remove all types of soils from ferrous substrates, including cutting oils, drawing compounds, coolant residues, smuts, dirt, and metal fines.


The low foaming wetting agents used in Dev-Kleen 3K-LF lead to the rapid loosening and dispersing of dirt and oils, and will split most oils from the cleaning solution, allowing skimmers to remove oil from the cleaning system, creating a economical cleaning system with a long tank life.
