ABSTRACT:
A solution containing approximately 40–60% by weight phosphoric acid, approximately 1–6% by weight a surfactant, approximately 0.5–5% by weight an inhibitor, and the remaining percentage by weight made up of water for removing magnesium chloride from certain materials, namely aluminum, aluminum alloys, steel, rebar, chrome, plastics, ceramics, rubber, including insulation on electrical wiring, and painted surfaces including those previously mentioned. The solution may be applied in various ways, including through a low-pressure sprayer or similar device used in car and truck washing service areas. Alternatively, the solution may be applied as a mask or coating, and after a period of time rinsed away from the contaminated surface.
