Gyeon Q²M Iron is one of the most efficient and fastest acting iron removers currently available, and was designed with the needs of professional detailers in mind. Formulated to dissolve brake dust and other iron-rich contamination upon contact, it is completely safe for use on all exterior surfaces (including trims and highly polished surfaces) in situations where ferrous compounds and sintered iron particulates are proving difficult to remove. Examples of such contaminants include railway dust, which can be highly resistant to all but the most aggressive clays, and iron-rich fallout, which can be hard to see but easy to feel with your fingertips.The main ingredient in Gyeon Q²M Iron is a highly reactive neutralised acid salt. This reduces ferrous compounds and particulates into a soluble form, making them easy to rinse away with water. As a result, Gyeon Q²M Iron is less aggressive than traditional acid-based cleaners, but equally as effective in terms of cleaning power. Gyeon Q²M Iron also contains a powerful detergent, which helps to break down everyday dirt and grime when it is applied to unwashed surfaces (e.g. wheels). Its gel composition means it clings to treated surfaces with ease, extending its working time and minimising the need for agitation in all but the most extreme cases.
