If the content of the gel-forming agent is less than the lower limit value, the viscosity of the water-based neutral rust removing composition may be low and it may flow down from the surface of the metal structure and may be difficult to use as a cleaning gel. The downside? We just don't promise, but we deliver the best quality and systems and sevices and practices. Some steels will emit more carbon in the rust removal process than others.
