NOXOL-678 is a near neutral pH formulation specifically designed and formulated to rapidly dissolve a wide range of contaminants many of which are frequently found in heat transfer systems. The range of contaminants removed includes oxides, carbonates, phosphates, halides of iron and calcium as well as other metal ions, and calcium sulfate.

In addition to removing the wide range of inorganic contaminants, moderate amounts of oil and/or grease present are also removed.
