GYEON Q²M PurifyMaintain "Purify Line" Antibacterial Spray Coating 500ml

Antibacterial sealing instead of just a wipe-down – GYEON Q²M PurifyMaintain for the interior

What makes GYEON Q²M PurifyMaintain different from a normal interior cleaner?
PurifyMaintain isn't a cleaner – it's a maintenance coating for interiors that already have GYEON Q²M Purify on them. It lays down a fresh antibacterial SiO₂ layer with no drawn-out prep. At the same time it actively goes after bacteria on treated surfaces and keeps the beading and dirt release of the Purify base coating alive.

An interior that looks clean and one that is hygienically protected are two different things. GYEON Q²M PurifyMaintain closes exactly that gap: inside the GYEON Purify line it is the maintenance product that refreshes, extends and tops up the antibacterial coating already in place. No deep clean, no full reapplication – spray it, spread it, and the protection is back. Ideal for cars in daily use that need to stay hygienic and well-kept.

• Active antibacterial agent: PurifyMaintain carries real antibacterial properties – bacteria on treated interior surfaces get knocked back, not just covered up.
• SiO₂ maintenance for lasting protection: The SiO₂ component wakes up the hydrophobic properties of the Purify base layer – liquids bead again, dirt gets less grip.
• Easy to use, nothing to strip out: Spray straight onto treated surfaces and spread it with a clean microfibre – no complicated prep needed.

Daniel's day-to-day tip: PurifyMaintain does its best work on surfaces that were sealed with GYEON Q²M Purify beforehand. For a first application, or on a heavily soiled interior, clean and seal it properly first, then use PurifyMaintain as a top-up every 4–6 weeks. That keeps the antibacterial layer working all the time.

The Purify line: a system, not a single product

With the Purify line GYEON built a properly thought-out system for car interiors: Q²M Purify as the base coating for the first seal, Q²M PurifyMaintain as the maintenance product for regular top-ups. You know the principle from paint care – a coating on its own isn't enough, what counts is the upkeep that follows.

PurifyMaintain is formulated so it doesn't smother or damage the base layer, but genuinely adds to it and builds it up. The antibacterial properties are switched on again with every application. That matters most in cars carrying a lot of people – rentals, taxis or family cars with kids – anywhere hygiene really counts.

How you use it: quick, regular, effective

You spray PurifyMaintain onto a surface you have already cleaned and spread it evenly with a clean, dry microfibre. No long dwell time, no rinsing. The layer flashes off fast and leaves a barely visible but active protective surface. For the best results work on dry surfaces and keep the car out of direct sun while you apply.

The recommended rhythm is every 4 to 6 weeks, depending on how hard the car gets used. On cars that are out all day, or through cold season, going more often makes sense. PurifyMaintain plays nicely with all the usual interior materials – synthetic leather, hard plastic, Alcantara and fabric – with a spot test first on anything delicate.

Which surfaces get the most out of it

Steering wheel, gear lever, door handles, armrests, dash trim – these high-traffic touch points pick up bacteria fast. PurifyMaintain is especially effective here because it doesn't just clean the surface, it actively protects it. After treatment those areas aren't only hygienic, they are easier to clean too – fingerprints and grime wipe off with far less effort, because the hydrophobic properties stop them keying in.

Synthetic leather seats and plastic trim benefit noticeably as well: the dirt release stays active between cleans, which stretches your cleaning intervals and cuts the work per clean.

Hygiene as part of the detailing routine

Interior hygiene was treated as a nice-to-have for a long time. Today it is a segment of its own in professional detailing – and PurifyMaintain is one of the few products that really tackles the hygiene side chemically, not just on the label. The antibacterial agent is tested to international standards and effective against a broad range of common bacterial strains.

For detailers working on other people's cars – private customers or a commercial fleet – PurifyMaintain is a genuine point of difference. A car that doesn't just shine but is demonstrably hygienic is a strong argument at handover. Pair it with the GYEON Q²M QuickDetailer for the outside and you have the full care routine covered.

PurifyMaintain in professional use

In a detailing business PurifyMaintain slots straight into the handover: run it as the last step on the interior once the full detail is done. The customer gets a car back that looks clean, smells fresh and is hygienically protected – and they can keep that protection going themselves with PurifyMaintain.

For the first seal on new or thoroughly cleaned cars we would start with the base Purify coating. PurifyMaintain is built as a top-up and extension – the system works best when both products run together.
