SONAX XTREME Car Interior Cleaner Interior Cleaner 500ml

Clean the interior thoroughly with no residue — SONAX XTREME Car Interior Cleaner

What makes the SONAX XTREME Car Interior Cleaner stand out? This all-round interior cleaner tackles plastics, upholstery, headliners and the dashboard in one step — with no hazing and no greasy film left behind.

The cabin is one of the trickiest cleaning jobs in detailing: within a few square metres you're dealing with wildly different surfaces — hard-plastic dashboards, fabric seat covers, soft faux-leather trim, rubber seals and textile headliners. The SONAX XTREME Car Interior Cleaner is built for exactly this: an all-purpose cleaner that reliably handles all of them without needing a bespoke formula for every single material. That saves you time, goes easy on the budget and makes interior cleaning far simpler. The formula leaves no sticky film, no whitish residue and no haze — which matters most on dark plastics and black trim.

• One cleaning formula for nearly every interior surface. From the dashboard to the door cards, right through to upholstery and headliners — this interior cleaner is cleared for a wide range of materials. That gives you a smooth workflow without switching between different products.
• No hazing, no greasy film once it's dry. A familiar headache with interior cleaners is the slightly greasy film that stays visible on plastics after drying and makes fingerprints stand out. The XTREME Car Interior Cleaner dries residue-free and leaves a clean, matt-clear surface.
• A fresh scent after cleaning, with no chemical smell of its own. Plenty of interior cleaners leave a harsh detergent or solvent smell that gives the cabin an unpleasant perfume. The XTREME interior cleaner has a pleasant scent and leaves a fresh feel once you're done.

Detailing1's tip from the shop: Spray the interior cleaner onto a slightly damp microfibre cloth — not straight onto the surface. That stops you soaking seams, panel gaps and air vents. On dashboards and door cards, work in sections: finish one area completely before you move to the next — that way nothing dries on before you get to it.

The interior cleaner formula — why all-round doesn't mean surface-level

With all-purpose cleaners a lot of people picture compromise products: something that does everything a bit but nothing really well. With dedicated car interior cleaners like the XTREME Car Interior Cleaner that isn't the case — and the reason sits in the formulation chemistry. The trick is picking surfactants that work equally well on hydrophilic (water-loving) surfaces like fabric and hydrophobic (water-repelling) plastics. The blend of mild anionic surfactants and amphoteric helpers lets it lift greasy fingerprints off plastics just as well as it pulls dried-in dirt out of upholstery. The pH sits slightly alkaline — strong enough to lift organic soiling like skin oils, food remnants and everyday grime, but gentle enough not to attack surfaces. On Alcantara, though, go easy with this all-round cleaner: for targeted stains there the specialist Upholstery+Alcantara Stain Remover is the better call. The all-round product suits general deep cleaning of most interior materials, but on sensitive premium textiles a product-specific cleaner is the safer bet. On hard plastic, rubber, standard fabric and faux leather, the XTREME Car Interior Cleaner is a no-reservations recommendation. It's also worth understanding that the cleaner has no care effect — it cleans but forms no protective film. If you also want to shield plastics from UV fading after cleaning, finish the workflow with a plastic dressing or cockpit detailer.

On dilution: the interior cleaner comes ready-to-use and isn't diluted any further. That's deliberate — the concentration is set for direct use on the cloth. Dilute it and you risk the cleaning power falling short on heavy soiling. The other way round, there's no need to lay on an over-the-top amount either: a moderate hit on the cloth covers a full surface. Dose sparingly and you get very solid value for money.

Using the interior cleaner right — step-by-step workflow

Before you start cleaning, it pays to give the interior a quick de-dusting. Loose dirt that's built up on trays, in the footwell and on the seats should come out first with a car vacuum. Skip that step and you risk stirring fine dust up with the cleaner and smearing it across clean surfaces instead of pulling it out. A quick vacuum before the wet clean makes the actual work far more effective and the result a lot cleaner. This prep step isn't mentioned in any product description, but it makes a big difference to the outcome.

The order of your interior clean is decisive for a good result. Always start at the top and work down: headliner first, then A/B/C pillars, then dashboard, then door cards, then seats, and finally the floor mats and carpets. That way dirt loosened while you clean always falls onto areas you haven't done yet, not onto freshly cleaned ones. For the dashboard: spray the cleaner onto a soft microfibre cloth and wipe with the grain of the plastic texture. On patterned or ridged surfaces a soft brush helps lift residue out of the recesses before you wipe with the cloth. For air vents and panel gaps a detailing brush or a folded microfibre cloth is ideal for working dust and dirt out of hard-to-reach spots. For seats and upholstery: the microfibre cloth should be slightly damp but not wet. On fabric upholstery you work in circular motions and dry the seat afterwards with a dry cloth, so no moisture stays behind in the padding. Door handles, control buttons and switches — every surface touched daily — get the most intensive clean, since that's where skin oils and fingerprints build up. Here the interior cleaner is especially effective, as it lifts greasy prints completely without damaging the surface.

For the best result on heavily soiled vehicles we recommend a two-stage approach: first run a base clean with the interior cleaner, lifting the coarsest layers of dirt. Once it's dry, check the surfaces again and spot-clean anywhere residue is left. This second pass is far quicker than the first but delivers a much cleaner result than a single pass under time pressure. On new vehicles or regularly maintained interiors, a single pass is plenty.

One more tip for working in winter: cold temperatures can slightly reduce the cleaning power, because surfactant activity is temperature-dependent. If you can, clean the interior in a heated garage or warm the vehicle up first. At room temperature the cleaner works at full strength and dries more evenly than in an ice-cold car. In summer, on the other hand, avoid cleaning the interior in direct sunlight, since the product can then dry too fast before you can wipe it off.

Where it works — the surfaces this interior cleaner handles

A common question is about smell during cleaning. Some cabins — especially after standing a long time, after winter, or in vehicles where someone has smoked — take on unpleasant odours. The interior cleaner itself doesn't remove odours from upholstery and textiles; it removes the dirt that's the source of the smell. In many cases light odours then disappear on their own. For strong smells like tobacco or pet odour, an odour neutraliser that works directly on the source helps on top. The combination of a thorough clean and targeted odour control delivers the complete result.

The SONAX XTREME Car Interior Cleaner is designed for these surfaces: hard plastics (dashboard, door cards, centre console), soft plastics (door pads, trays), rubber (seal frames, pedal pads), standard textile upholstery (fabric seat covers, carpets), faux leather and PU coatings, plus textile headliners. And the formula treats all of them the same in method and dwell time: spray onto cloth, wipe, let dry. No long dwell times, no special tools. That makes the interior cleaner especially appealing for businesses that have to turn round a lot of vehicles in a short time. A base interior clean with the XTREME Car Interior Cleaner takes about 20–40 minutes on a normal car, depending on how dirty it is and how carefully you work. If you want to finish by spot-treating individual problem stains on upholstery, reach for the XTREME Upholstery+Alcantara Stain Remover for pinpoint follow-up.

One use case that rarely gets a mention: the product also works for cleaning boots, load areas and trim in the rear of the vehicle. Especially on SUVs, estates and vans, faux-leather or hard-plastic load areas take a real beating from dirt. The interior cleaner handles these areas just as reliably as the actual passenger compartment. Trailer interiors, motorhome trim and boat interiors are possible use cases too, as long as the surfaces fit the product's material range.

For vehicles with especially light interiors — white or light-beige leather and faux leather — the usual rule applies: test on an inconspicuous spot first. Light surfaces react more sensitively to residue than dark ones. The interior cleaner is formulated residue-free, but on light surfaces a particularly careful dry-off is worthwhile to avoid any faint trace.

Interior cleaner comparison — XTREME vs PROFILINE and specialist cleaners

The SONAX range has several interior cleaners serving different demands. The all-round everyday cleaner is ideal for beginners and occasional users: affordable, versatile, quick to use. For heavy professional use in businesses, SONAX offers the PROFILINE InnenReiniger, which is more concentrated, available in larger containers and optimised for especially stubborn interior soiling. The PROFILINE cleaner can also be diluted — an important advantage for businesses that want to run the same cleaner at different strengths depending on the job: highly concentrated for heavily soiled vehicles at intake, more diluted for the weekly refresh. If you specifically want to clean only plastic surfaces in the interior while dressing them at the same time, the range includes the XTREME CockpitReiniger "Matt-Effect" as a specialist option for plastic surfaces with a subtle care effect and a matt finish. For most private and semi-pro users the XTREME Car Interior Cleaner is the right way in: the 500 ml bottle covers plenty of jobs, the price is attractive, and handling is completely fuss-free. If you want to go deeper and regularly detail vehicles professionally, you'll move to the concentrated PROFILINE products in the medium term — but as a first interior cleaning product or an add-on for getting started, the XTREME interior cleaner is spot on.

It's also worth watching for synergies in your own detailing kit: if you use the interior cleaner regularly, it pays to keep a dedicated upholstery cleaner for the seats and a plastic dressing for the dashboard within reach as well. The combination of cleaning, stain removal and dressing covers the complete interior workflow — fast, effective and with a professional result.

Finally, a note for anyone wondering whether the XTREME Car Interior Cleaner also suits older vehicles with faded or degraded plastics: yes, with a caveat. The product cleans reliably but can't visually restore faded surfaces — that's the job of a plastic dressing or cockpit dressing. On very old, worn-out plastics that are already roughened or porous, we recommend working especially gently and using no abrasive motions. The cleaning still works there, but the look of the plastics themselves only improves with a follow-up dressing step.

Buying recommendation — who the XTREME Car Interior Cleaner is the first choice for

A practical question first: is the 500 ml bottle enough for a vehicle? Yes, easily — at normal dosing onto a microfibre cloth you use only a few millilitres for a full interior clean on a car. A bottle lasts many months, even with regular use. For detailing businesses working several vehicles a day, the 500 ml bottle is more of a consumable, which is why the PROFILINE version in larger containers is more economical there.

If you want an all-round interior cleaner that delivers a reliable result without much hassle, the SONAX XTREME Car Interior Cleaner is a clear tip. It's especially suited to vehicle owners who care for their interior regularly and don't want a specialist cleaner for every surface. The 500 ml bottle is enough for plenty of full interior cleans — dose sparingly onto the cloth and it easily lasts twenty or more applications. For families with kids, who often leave dirt and food remnants in the cabin, a reliable all-round cleaner like this is a must. For used-car dealers and detailers prepping vehicles daily, the product is ideal as a standard cleaner — paired with a vacuum and a good microfibre cloth it forms the basis of every professional interior job. If you then want to finish the vehicle with a protective touch, round off the workflow with a plastic dressing for the dashboard and door cards and a textile-protection spray for the upholstery. The XTREME Car Interior Cleaner is deliberately the first step, not the last — a thoroughly cleaned interior is the precondition for any dressing step that's worth doing.

For anyone wanting to know how often the interior should be cleaned: as a rule of thumb, once a month with normal use and after every longer holiday or winter run. With intensive use — vehicles run daily for car-sharing, as company cars or in commercial passenger transport — a weekly base clean of the heavily used contact surfaces is worthwhile. If you often bring snowy or muddy shoes into the car in winter, do the floor mats more often. In summer skin-oil residue mainly builds up on the steering wheel, gear lever and door handles — here a quick weekly clean pays off to stop layers building up. Regular care keeps the effort small and the result presentable at any time.
