SONAX PROFILINE Interior Detailer Concentrate Interior Cleaner 1000ml

One Liter of Concentrate for Every Interior Cleaning Job — SONAX PROFILINE Interior Detailer Concentrate

What can an interior cleaner concentrate do that a ready-to-use spray cannot? The professional concentrate detailer from SONAX can be diluted from 1:10 to 1:50, depending on the degree of soiling — one liter yields between 10 and 50 liters of ready-to-use solution for textiles, leather, plastic, and metal.

Anyone who regularly cleans vehicle interiors knows: the cleaning effort varies enormously — there's a world of difference between a slightly dusty rental car and a heavily soiled commercial vehicle. A single spray for all situations is a compromise — either too strong for delicate surfaces or too weak for stubborn dirt. The SONAX PROFILINE Interior Detailer Concentrate solves this problem with a variable mixing ratio: from 1:10 for intensive cleaning of heavily soiled surfaces to 1:50 for gentle care of delicate materials — always from the same concentrate, always tailored to the current job.

• Variable mixing ratio from 1:10 to 1:50 for every application. The concentrated formula gives the user control over the cleaning intensity. 1:10 is suitable for heavily soiled plastics, ingrained textile floors, and worn steering wheels; 1:30 to 1:50 for delicate leather, Alcantara, and headliner surfaces that are only lightly dusty. One concentrate thus replaces several different ready-to-use products with different strengths — economical and space-saving for professional use.
• Antistatic effect keeps dust away permanently. The formula contains antistatic agents that build a protective layer on the surface after cleaning, preventing electrostatic charges. Plastic and rubber surfaces in the vehicle interior tend to accumulate electrostatic charges, which magnetically attract household dust and fine dust — the reason why cleaned dashboards often get dusty faster than other surfaces. With the antistatic protection, the cleaned surface remains significantly cleaner for longer after treatment.
• Silicone-free formula — safe for all interior surfaces. The Interior Detailer Concentrate is silicone-free. Silicone leaves a shiny film on plastics that traps dirt, dulls the surface over time, and poses a safety risk on airbag modules and steering wheel grips. The silicone-free formulation leaves no greasy residues — textiles remain breathable, leather retains its natural grip, and hard plastics get a subtle, non-intrusive sheen.

Practical tip from Detailing1: For professional use, it is advisable to prepare several pre-mixed spray bottles with different dilution levels: one bottle at 1:15 for plastics and door panels, one at 1:30 for seats and textiles, and one at 1:50 for headliners and delicate leather parts. This saves remeasuring for each vehicle and provides direct access to the appropriate strength. When using on the vehicle headliner, always spray onto a microfiber cloth first, never directly onto the headliner — direct wet application can loosen the adhesive on glued headliners. Do not use on windows, displays, or navigation devices; for glass cleaning, a dedicated glass cleaner is the cleaner choice.

Concentrate Formula — How SONAX PROFILINE Interior Detailer Concentrate Works on Various Interior Surfaces

The concentrate detailer from the PROFILINE range is designed for cleaning the entire vehicle interior, with the exception of glass, displays, and electronic surfaces. The formula combines surfactant-based cleaning components with conditioning agents: the surfactants dissolve grease, fingerprints, dust, and organic contaminants from surfaces; the conditioning components strengthen the cleaned surface, prevent electrostatic charge, and leave a subtle protective film. This dual function — cleaning and conditioning in one step — is the core advantage over pure cleaners without conditioning agents.

On textile seats and floors, the Interior Detailer works through mechanical and chemical dirt removal: the concentrate is applied to a microfiber care pad or cleaning brush, the fibers are opened by the movement, and dirt is lifted from deep within. The surfactant's lubricating ability reduces friction resistance during scrubbing, allowing even deeper dirt to be loosened without excessive force. For heavily soiled textiles, use the 1:10 mixture, let it sit briefly (30–60 seconds), and then work it in with a steam extractor or wet microfiber cloth.

On leather, dilution is crucial: genuine car leather, especially older leather interiors, reacts sensitively to over-cleaning. The Interior Detailer Concentrate should be used on leather in a 1:30 to 1:50 dilution — a too concentrated solution can dissolve the natural oils from the leather and dry out the surface in the long term. After cleaning leather with the concentrate, a leather care step with a nourishing leather cream to replenish lost oils is ideally followed. The Interior Detailer Concentrate is a cleaner, not a leather conditioner — this separation of tasks in the workflow is important for long-lasting leather interior care. Those who want to do both in one step can use a dedicated leather care product; those who clean sequentially and then condition will achieve a more thorough result because the conditioner is applied to an already cleaned, open-pored surface.

On hard plastics — dashboard, door panels, center console — the concentrate in a 1:15 to 1:20 dilution provides the best combination of cleaning performance and subtle conditioning. The antistatic after-effect is most noticeable on plastic: anyone who has treated their dashboard with the Interior Detailer Concentrate will notice that it takes significantly longer for dust to accumulate again compared to untreated plastics. Shiny plastic panels that show fingerprints should be treated with a softer cloth and a stronger dilution to avoid micro-scratches.

Applying Interior Detailer Concentrate — Dilution, Spray Bottle, and Procedure

The application of Interior Detailer Concentrate begins with preparing the ready-to-use solution: pour concentrate into a spray bottle, then fill with water to the desired ratio (always concentrate first, then water — this minimizes foam formation when filling). For standard cleaning of plastics and textiles, 1:15 is a good starting point. Shake the bottle lightly, then spray onto the material to be cleaned.

Application should always be to a microfiber cloth or foam applicator, never directly onto sensitive surfaces such as headliners or Alcantara. On robust surfaces such as rubber floor mats or heavily soiled plastics, it can be sprayed directly. Guide the cloth evenly over the surface, either in a circular motion or in the direction of the fibers (always in the direction of the fibers for Alcantara). For seams, textures, and panel gaps in the dashboard, a soft detailing brush is recommended to work the concentrate into hard-to-reach areas.

Dwell time is not necessary for normal soiling — the formula works immediately upon application and working in. For more stubborn dirt (dried-on food, dirt rings in seat creases), leave the solution on the surface briefly (30–60 seconds) to allow the surfactants to soften the dirt. Then work it in with the cloth. Remove excess with a clean, dry microfiber cloth and allow the surface to dry. The result after drying: a clean, subtly conditioned surface without streaks, greasy film, or residue.

For working on door sills and footwell corners, where dirt stubbornly settles in crevices, a more concentrated solution (1:10 to 1:15) combined with a thin detailing brush is suitable. The brush applies the concentrate into the crevices, mechanically loosens the dirt, and a damp cloth wipes away the loosened particles. This workflow works particularly well on rubber-edged door sills, where silicone-containing products often leave streaks, which the Interior Detailer Concentrate naturally avoids due to its silicone-free formula.

The 1-liter concentrate is not intended for single-use home application, but for portioned use over a long period. At a 1:20 mixture, 1 liter of concentrate yields 20 liters of ready-to-use solution — for a professional operation with 3–5 vehicles daily, this is easily enough for several weeks. The bottle should be stored in a dry, cool place; the concentrate is stable and will last for many months with proper storage.

Antistatic, Scent, and Surface Compatibility — What Sets the Interior Detailer Apart

The antistatic property of the Interior Detailer Concentrate is one of the most noticeable advantages in everyday use. Anyone who regularly cleans their vehicle knows the problem: hardly has the dashboard been wiped clean, it has a thin layer of dust again after a few days. This rapid re-soiling is physically caused: plastic surfaces become electrostatically charged by friction while driving and attract dust particles from the air. The antistatic agent in the Interior Detailer Concentrate neutralizes this charge after cleaning — the surface is electrically neutral after treatment and attracts dust significantly slower. The more regularly the product is used, the more stable this protective effect becomes.

Another aspect of the antistatic effect concerns durability after cleaning: treated surfaces must be cleaned at shorter intervals if antistatic protection is not used. Anyone who previously had to wipe down their interior weekly will find, after regular treatment with the Interior Detailer Concentrate, that bi-weekly maintenance is sufficient to maintain the same standard of cleanliness. This accumulates over a year to significantly less cleaning effort — a practical effect that goes beyond mere cleaning performance.

The fragrance experience of the Interior Detailer Concentrate is unusually pleasant for a professional cleaner: the formula contains subtle aromas of coconut and pineapple, which leave the interior smelling fresh and pleasant after cleaning — without the sharp chemical smell of many industrial interior cleaners. For customer contact situations (car dealership detailing, vehicle handover after detailing), this is a relevant detail: the interior smells clean, not of cleaning products.

The concentrate is not suitable for glass surfaces, displays, touchscreens, and navigation devices. These surfaces have special coatings (anti-fingerprint coatings, oleophobic coatings) that can be attacked by the surfactant formula of the Interior Detailer Concentrate. For glass cleaning in the vehicle interior, the SONAX PROFILINE Interior Cleaner is suitable as a supplement for non-glass surfaces; for windows, a dedicated glass cleaner. The clear distinction: Interior Detailer Concentrate for all non-transparent interior surfaces, glass cleaner for windows and displays.

Interior Detailer Concentrate Compared — vs. Interior Cleaner and SensitiveSurface Detailer

In the SONAX PROFILINE interior range, there are three main products with clear positioning. The SONAX PROFILINE Interior Cleaner is the ready-to-use all-purpose spray for quick cleaning without mixing effort — ideal for frequent interim cleaning and businesses that want cleaning products readily available without measuring. The Interior Detailer Concentrate, on the other hand, is the concentrate for variable cleaning intensity — more control over strength, more economical for large quantities, more flexible in use.

The SONAX PROFILINE SensitiveSurface Detailer is the specialist product for delicate surfaces: Alcantara, velour, microfiber interiors, and other textured materials that can become streaky or dull with normal cleaners. It is not available as a concentrate and has an even gentler formula than the Interior Detailer Concentrate at maximum dilution. For vehicles with Alcantara inserts in the cockpit or sports bucket seats, the SensitiveSurface Detailer is recommended for these specific areas, while the Interior Detailer Concentrate handles the rest of the interior.

A note for businesses using SONAX PROFILINE CleanStar "Ecocert": The Ecocert product is the bio-certified alternative for businesses with a sustainability focus — it contains only ingredients approved according to the Ecocert standard. The cleaning performance is comparable to the Interior Detailer Concentrate at medium dilution, but without the antistatic component. For businesses without sustainability requirements, the Interior Detailer Concentrate is the more powerful all-round choice.

Buying Interior Cleaner Concentrate — Target Group, Economy, and Recommendation

The SONAX PROFILINE Interior Detailer Concentrate is the main product for professional detailing businesses that clean multiple vehicle interiors daily and require maximum flexibility with minimal storage. One liter of concentrate replaces 10–50 liters of finished product depending on dilution — an enormous logistical advantage for workshops with limited storage space and high cleaning volumes. The economy speaks for itself: in terms of cleaning performance to price, the concentrate beats almost any ready-to-use alternative.

For ambitious hobby detailers with multiple vehicles or a vehicle that is regularly intensely detailed, the concentrate also makes sense. Anyone who maintains their interior monthly and always needs the right strength for different materials will benefit from the mixing flexibility just like a professional. The extra effort of mixing is manageable with a prepared set of spray bottles.

Anyone using the concentrate for the first time should start in an inconspicuous area of the vehicle — especially with unknown synthetic leather or Alcantara variants. Although the Interior Detailer Concentrate is suitable for all common interior surfaces, there are variants of very old or damaged leather as well as cheap synthetic leather imitations that can react to surfactant-containing cleaners with a slight color change. A brief test spot is generally recommended for valuable interiors, regardless of which cleaning product is used.

The concentrate is less suitable for occasional users who need it once or twice a year and do not want to keep a ready-to-use spray bottle permanently available — in this case, a ready-to-use interior cleaner is more practical. As a verified SONAX specialist dealer, Detailing1 permanently stocks the PROFILINE Interior Detailer Concentrate in the 1-liter container size, which is designed for continuous professional use. Those who want to set up a starter kit for professional interior detailing should ideally combine the concentrate with a set of good microfiber care cloths in different strengths (for plastic, textile, and leather separately), a detailing brush for crevices, and a steam cleaner for intensive deep cleaning — the Interior Detailer Concentrate then becomes the chemical core that drives all these tools.
