Gyeon Q²M Iron

by Gyeon

We Say

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.

Cleaning Strength10/10(Compared To Others)


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.

How To Use

Gyeon Q²M Iron comes pre-diluted to the correct strength for safe use on all exterior surfaces. In all cases, wash and rinse the surfaces you are going to treat in the normal way. Next, working on 1-2 wheels or 3-4 panels at a time, spray Gyeon Q²M Iron on liberally and allow up to 10 minutes for it to work; during this interval it will gradually turn purple as ferrous compounds and sintered iron particles dissolve into solution (this effect can be very pronounced, but don't panic because it's quite normal and to be expected).

Although Gyeon Q²M Iron is essentially a touchless cleaner, you can agitate it with either a brush (on wheels) or a microfibre towel (on bodywork and glass) if needs be. After 10 minutes or so, i.e. once the dark purple solution has started to dry (it's perfectly safe to let Gyeon Q²M Iron dry out, provided that you are working somewhere cool and out of direct sunlight), rinse the surfaces you have treated with a strong stream of water. Note that if the solution has dried fully you may need to use a stronger jet of water from a pressure washer to remove the residue.

After rinsing off, check the treated surfaces for residual contamination by running your fingertips over them while they are still wet. Contaminant-free surfaces should feel perfectly smooth (if your fingertips aren't particularly sensitive you can magnify your sense of touch by putting your fingers inside a cellophane wrapper first). If you can detect any grittiness then it's likely that the treated surfaces are still contaminated with non-ferrous particulates (e.g. paint overspray) and will need to be carefully clayed before any polishing is done or any protection is applied.
