Ardrox® 188 is an alkaline powder blend containing an oxidizing material, while Ardrox® 188RFU (Ready For Use) is the liquid version of Ardrox® 188 powder. These products are primarily intended to aid in the removal of difficult heat scales, such as those produced on high chromium steels and nickel and cobalt alloys, which are notoriously hard to remove even with strong acids. Ardrox® 188 or Ardrox® 188RFU typically do not remove such scales by themselves but chemically and physically modify them to make them more easily removable by milder and less dangerous methods than using strong acids. The primary application for Ardrox® 188 or Ardrox® 188RFU is in the overhaul of "hot end" components of gas turbine engines.
