METKLEEN 2200 is a liquid, acidic cleaner used to clean, deoxidize, descale and derust metals. METKLEEN 2200 will passivate and pickle metal surfaces to improve paint or plating adhesion. METKLEEN 2200 can be used in “rework operations” to simultaneously clean and derust parts. This cleaner is the ideal choice to remove rust, white rust, weld spatter, heat scale, or other corrosive deposits on ferrous and non-ferrous metals.
