Ardrox 1900-B is a thickened, heavy-duty alkaline product formulated to clean the exteriors and interiors of aircraft and ground handling equipment. It clings to the surface and rapidly wets out the soil and can be used for wet or dry washing. A blend of alkalies, water soluble solvents, and wetting agents, Ardrox 1900-B has a pleasant lemon odor. It does not contain petroleum solvents or phosphates. Ardrox 1900-B rinses off easily and completely, leaving a streak-free, spot-free surface.
