GYEON Q²M RestartWash Decontamination Shampoo for Coatings 1000ml

Remove Contaminants Before They Cause Damage – GYEON Q²M RestartWash as a Decontamination Shampoo

What is the advantage of a decontamination shampoo over a normal car shampoo?
A normal car shampoo removes loose dirt – road dust, pollen, bird droppings. What it doesn't remove: chemically bonded contaminants like iron particles from brake dust, tar spots, industrial fallout, and limescale. These embed themselves deep into paint pores and sealants and are not removed by normal washing. GYEON Q²M RestartWash contains active decontamination components that dissolve precisely these substances – in a single wash.

Even after a thorough regular wash, a vehicle often doesn't look as clean as it should. The reason is often chemically bonded contaminants that accumulate over time: iron particles from brake dust, which settle as brown streaks in the paint, tar and resin splashes, industrial fallout, and limescale. GYEON Q²M RestartWash combines the cleaning power of a high-quality car shampoo with active decontamination components – iron remover, tar remover, and limescale remover in one product. A wash that truly starts fresh.

• 3-in-1 Decontamination in one wash: Iron remover, tar remover, and limescale removal components work simultaneously – no separate pre-wash step with individual products is needed.
• Coating-compatible formula: RestartWash is specially developed not to damage existing coatings and sealants – ideal for maintenance washing of coated vehicles.
• Visual feedback through color reaction: The iron remover component reacts with iron particles and visibly changes color – you can see where and how much contamination has dissolved.

Practical tip from Daniel: Use RestartWash most effectively on pre-wetted, cool paint. In the sun or on hot metal, the product dries too quickly and leaves residues. The color reaction (purple-red) shows you where iron contamination is present – let the product work for 2-3 minutes before rinsing. For heavy contamination, a subsequent application of GYEON Q²M Iron as a targeted treatment can be useful.

Why Regular Washing Alone Isn't Enough

Brake dust iron particles are the most common and often most invisible contamination problem on vehicles. Hardly visible to the naked eye, they embed themselves in clear coat and sealants, oxidize, and create those typical brown streaks on light-colored vehicles. On dark vehicles, they are often only visible when touched or under glancing light.

Normal shampoos have no mechanism to dissolve these chemically bonded particles – they glide over them. GYEON Q²M RestartWash contains chelating compounds and reducing substances that convert iron particles into soluble compounds, thereby removing them from the surface. This is the fundamental difference from conventional washing.

Application as a Two-Bucket Wash

RestartWash can be directly integrated into the normal washing process. The shampoo is mixed with water in the usual ratio (depending on the desired concentration and degree of contamination), the vehicle is rinsed beforehand, and then washed using the two-bucket method. The decontamination components work automatically during the washing step – no separate pre-spraying and dwell time are necessary.

For maximum effect with heavier contamination, first spray the vehicle with undiluted RestartWash after pre-rinsing and let it dwell for 2-3 minutes before the actual wash begins. The color reaction of the iron remover component indicates where and how much iron contamination is present. Afterwards, rinse thoroughly and wash as usual.

Especially Valuable for Coated Vehicles

Coated vehicles require a particularly gentle yet effective care routine. Conventional decontamination products can have aggressive pH levels that attack coatings. RestartWash is specifically formulated for coated vehicles – the pH value is balanced, and the active ingredients are precisely selected. This ensures decontamination is carried out without compromising the invested sealant.

Used regularly – every 4 to 8 weeks depending on mileage and braking intensity – RestartWash prevents the build-up of chronic contamination layers that can weaken even the best coatings in the long run. The paint remains smooth, the sealant functions optimally, and the vehicle is truly clean – not just visually.

RestartWash Positioned in the Detailing Workflow

In the professional workflow, RestartWash takes the place of both the pre-wash step and the basic shampoo. For many detailers, this means: fewer products, fewer steps, the same or better results. For vehicles that are only detailed every few weeks, a RestartWash wash is the ideal start to any care cycle.

After washing with RestartWash, we recommend a visual inspection under glancing light. Remaining resin or tar spots can be treated locally with GYEON Q²M Tar. After that, the vehicle is truly ready for the next care or sealing stage – whether QuickDetailer, coating refresh, or complete re-sealing.

The Result: A True Restart

The name RestartWash says it all: the vehicle gets a real restart after treatment – freed from all chemically bonded contaminants that have accumulated during normal washing. Paint and sealant can perform optimally again. Water beads better, the gloss appears deeper, and the next protective layer – whether GYEON Q²M WetCoat directly after washing or a cured coating – adheres more reliably to a truly clean surface.

In short: those who use Q²M RestartWash regularly will less often have to resort to more aggressive decontamination agents, protect their sealant, and ensure their vehicle remains in the best condition long-term.
