STM-62 is a concentrated, granular equipment cleaning compound for use both manually or with high-pressure equipment. Its concentrated formula tackles the toughest grime and makes STM 62 an economical choice. Its foaming action is easily rinsed and does not leave streaks with normal water and concentrate. It leaves no residue and is safe for most painted metal surfaces. It is for use in either hard or soft water and emulsifies oil and grease and will not harm skin or clothing. SRM 62 dissolves completely and readily so it will not clog pressure systems.  It is also biodegradable.
