Freiclean 209LF is a liquid, alkaline, medium to heavy duty, low foaming spray cleaner designed to remove oils and lubricant soils from steel. Freiclean 209LF is potassium based for easier rinsing resulting in less downstream contamination of subsequent processes. Freiclean 209LF is effective where exceptionally oily soils are present. Oily soils may be skimmed from the surface of the cleaning solution. Freiclean 209LF is typically used for cleaning steel substrates in general parts washing applications and prior to conversion coatings and paint application.
