Corrosion [: Water has a low electrical conductivity, but this increases significantly with the dissolution of a small amount of ionic material such as sodium chloride. Sodium chloride CI and water H2O produce oxides, which in turn cause corrosion] Use ValuGard Decontamination System (B) alkaline neutralizer (pH 1.0) that is a blend of acids, which deep cleans painted surfaces to remove alkaline road salt / water solution deposits, pH 9.0 used for freezing point depression in a sprayed brine solution (often mixed with grit / sand for tyre adhesion) and safely dissolves salt particles bond with the paint so that they can be rinsed away. Apply to a clean and freshly rinsed surface. Allow product to dwell for 5-7 minutes, works well with detailer’s clay to remove hardened surface contaminants. All necessary safety precautions should be taken whilst using this product. Protect paint surface with a synthetic polymer sealant Collinite's Insulation Wax # 845 or Finish Kare FK1000P (see also Undercarriage Care and Road Salt)
