Product Description

Product Description

ZERUST® AxxaWash™ KMS-220 is an ideal part cleaner fluid for removing light-duty hydrocarbon soils and particulates on ferrous substrates. Following cleaning, you may rinse and remove AxxaWash™ KMS-220 from the metal surface using RO, D/I, or distilled water or left on the metal surface as a dry-in-place part cleaner and flash-rust inhibitor. Alternatively, AxxaWash™ KMS-220 part cleaner contains a mild flash-rust corrosion inhibitor and is, therefore, particularly effective for cleaning and preparing metal surfaces for a long-term rust preventative, such as ZERUST® Axxanol™ or Axxatec™ product lines. Consequently,  AxxaWash™ KMS-220, available as a liquid concentrate, allows for dilution according to the application. Additionally, AxxaWash™ KMS-220 does not contain alkylphenol ethoxylates, boron salts, phosphates, silicates, or solvents, is non-flammable, and complies with Global Automotive Declarable Substance, TSCA, and RoHS requirements. Furthermore, speak with your ZERUST®/EXCOR® sales representative to obtain your operator guide.
