Gyeon Q²M Iron is an intensive cleaner designed to dissolve brake dust and iron-rich fallout upon contact. Fallout bonds to exterior automotive surfaces both physically (by charge attraction) and chemically (by electrolysis), and typically contains ferrous compounds and particulates derived from industrial and commercial activities. As such contaminants gradually accumulate on bodywork, surface roughness gradually increases to the point where it can be felt, while the reflectivity of the finish and the ability of the paint to sheet water properly gradually diminishes. Furthermore, as such contaminants oxidise and corrode, caustic compounds may leach out and stain underlying surfaces. The periodic removal of such contaminants is therefore an important part of detailing, and should be performed once or twice a year.
If you're familiar with detailing clay you'll know that it's designed to remove bonded surface contaminants, but what it never says on the tin is that it often struggles to fully remove ferrous compounds and sintered iron particulates. By working chemically rather than physically, Gyeon Q²M Iron instantly reacts with ferrous compounds and sintered iron particulates and chemically reduces them to a water soluble complex that can be easily rinsed away. This process can be seen to be working with the naked eye, as the initially transparent solution gradually turns purple as it dissolves any iron particles it comes into contact with. A powerful detergent completes the process, by dissolving and lifting away residual dirt and grime. Although Gyeon Q²M Iron is pH balanced, it is a professional strength product and should therefore be used with care.
