It is an acidic product. It is used to remove the oil, iron, steel, aluminum and galvanized parts and to cover with a thin layer of phosphate. It is applied by wiping the metal surface with an absorbent object by mixing with 5-10% concentration of water. To remove the deep rust layer formed on the steel and iron surface, the concentration should be preferred between 10-20%. As the temperature increases, rust and oil removal will be accelerated. Requires rinsing and drying after this process.
