This liquid quickly removes rust from iron, without corroding it or reducing its strength (shiny metal immersed in the material does not lose its shine for days) while at the same time cleaning it from oils, tars, greases, certain paints, etc. When the object is rinsed, it does not rust easily! With this use, it achieves excellent results not only in quickly removing rust from iron objects, but also in cleaning boilers and hot water circuits from salts and rust, oils, tars, paints, etc.
