SONAX CleanStar "Ecocert" Interior Cleaner 750ml

Clean all interior surfaces simultaneously — with SONAX CleanStar EcoCert

What can SONAX CleanStar EcoCert do? This universal interior cleaner cleans all surfaces in the vehicle interior — from glass to Alcantara to touchscreen displays — streak-free, material-friendly, and with ECOCERT Greenlife certification.

Anyone who regularly maintains a car's interior knows the problem: you need one product for leather, another for plastic, and a third for windows — and as soon as a sensitive touchscreen display or a piano black trim comes into play, cleaning becomes a fundamental question. The SONAX CleanStar EcoCert solves this problem with a single product: a mild, ready-to-use spray bottle that cleans all materials in the vehicle interior — without residue, without streaks, and without the risk of surface damage to sensitive areas. Added to this is the ECOCERT Greenlife certification — a quality feature for detailers who pay attention to the composition of their care products.

• One formula for all interior surfaces. Glass, piano black, fabric, Alcantara, leather, plastic, touchscreen displays — the CleanStar works on all these materials without streaks, residues, or discoloration. You save yourself the constant switching between different cleaners and work more quickly and systematically through the entire interior, without compromising cleaning performance.
• ECOCERT Greenlife certification for a clear conscience. The cleaning agent is certified by ECOCERT Greenlife according to the ECOCERT Standard — this means the ingredients meet defined requirements for biodegradability and environmental compatibility. For detailers who value product responsibility or want to convince their customers with an ecological quality promise, this is a real difference compared to conventional interior cleaners without certification.
• Odor neutralizer instead of fragrance masking. The interior cleaner contains an active odor neutralizer that chemically neutralizes unpleasant odors in the vehicle interior — not just masking them with perfume. After cleaning, a pleasant, fresh scent remains, enhancing the interior without appearing artificial or overpowering. This is a noticeable advantage, especially for vehicles with smoke or food contamination.

Practical tip from Detailing1: Always spray CleanStar directly onto a microfiber cloth, not onto the surface — this prevents overspray onto adjacent materials and gives you more control over moisture application. On touchscreens and piano black surfaces, work with minimal pressure and immediately wipe with a dry, clean cloth. For stubborn upholstery stains, rinse the cloth with clean water in between and re-spray — repeat until the cloth remains visibly clean when wiping. This prevents you from rubbing already absorbed dirt back into the surface.

Interior cleaner for all surfaces — how the CleanStar's universal formula works

Most interior cleaners are optimized for one material class: either plastic, glass, or textiles. A true universal cleaner, however, must work on very different surfaces — from smooth, water-repellent glass and piano black surfaces to porous textiles and upholstery to sensitive microfiber materials like Alcantara. The SONAX CleanStar EcoCert achieves this with a mild, pH-neutral formulation that dissolves dirt without swelling, bleaching, or leaving residues on materials.

The basic principle: The cleaner breaks the adhesion between dirt molecules and the surface, so you pick up the dissolved dirt with the microfiber cloth instead of rubbing it deeper into the surface. On absorbent materials like fabric or Alcantara, the streak-free drying formula prevents watermarks — a common problem with cleaners that have too high a surfactant concentration, which leaves white marks or spots when drying. On non-absorbent surfaces like glass or high-gloss plastic, residual moisture evaporates without residue, allowing for streak-free results even without intensive re-wiping.

The ECOCERT certification not only concerns the ecological aspect but is also an indirect quality signal for the formulation: Certified surfactants and ingredients must meet certain biodegradability and compatibility standards, which in turn means that particularly aggressive or poorly biodegradable chemicals are excluded. This reduces the risk of undesirable reactions on sensitive materials — which helps explain why the cleaner can be used on so many different surfaces without specific compatibility tests.

Interior cleaner for touchscreen and piano black — what makes this cleaner special

Sensitive areas like infotainment touchscreens, high-gloss piano black trim, and matte paint surfaces require special care. Aggressive cleaners can leave micro-damage on these surfaces: touchscreens lose their oleophobic protective layer and become less functional, piano black shows fine wiping marks or haziness, and matte surfaces develop unwanted glossy spots in areas of friction. The CleanStar is explicitly approved for these surfaces — the formula is so mild that it does not attack protective layers or change the character of the surface.

For touchscreens and piano black, both the product and the application technique are crucial: low moisture on the cloth, minimal pressure, no circular rubbing movements, but rather straight wiping movements parallel to the surface. For piano black, a single pass with a soft microfiber cloth is recommended, followed by a dry lint-free cloth or glass polishing cloth. On reflective touchscreen displays, the result is streak-free, provided the cloth itself is clean and free of coarse particles — a dirty or fibrous cloth is the most common cause of scratches on displays and high-gloss areas, not the cleaning product.

The CleanStar is also particularly practical for modern vehicles where touchscreens on dashboards alternate with adjacent plastic surfaces, leather trim, or aluminum inserts. Instead of keeping several products at hand and switching for every material change, you work through the entire cockpit area with a single cloth and a single bottle — saving time and reducing the risk of applying the wrong product to the wrong surface.

Interior cleaner for Alcantara, leather, and plastic — an overview of applications

The interior of a modern vehicle is a mix of materials: dashboard and door panels in hard plastic or soft-touch paint, seats in fabric, leather, or Alcantara, headliner in textile, center console in piano black or aluminum look. In addition, there are rubber seals, carpet areas, steering wheel, and gear knob — each material has its own surface and its own sensitivity. The SONAX CleanStar EcoCert covers all these areas; you can use it for a complete interior pass without changing the product.

On leather, the cleaner removes surface dirt, grease deposits, and light stains without stripping the natural moisture from the surface. However, it's important to note: cleaning does not replace leather care. After cleaning with CleanStar, a follow-up treatment with a SONAX PROFILINE LeatherCleaner or a leather conditioner is advisable to restore moisture and keep the leather surface supple in the long term. Anyone who cleans leather intensively and then does not care for it risks drying out and cracking in the long run.

On Alcantara, the cleaner dissolves grease stains, light everyday dirt, and odor particles without damaging or matting the characteristic velour textile structure. Important when working on Alcantara: always use little moisture and wipe in a uniform direction (following the nap), never rub in circles. After cleaning, let it dry briefly and then brush it up with a dry, soft cloth or a soft brush if necessary to restore the texture. For deep-seated dirt or stains that do not completely disappear after a single application, a second treatment or a specialized upholstery stain remover may be required.

On hard plastics, rubber surfaces, and carpets, the cleaner shows its strongest side: here it can be used with a little more pressure and a little more moisture, without risk to the surface. Especially on heavily soiled carpets or floor mats, it is advisable to let the cleaner sit briefly (30-60 seconds) before working with the cloth — this gives it time to loosen the dirt before you pick it up.

Comparison: CleanStar EcoCert vs. other interior cleaners

Compared to specialized products, the CleanStar has a clear advantage: if you want to completely clean the interior of a vehicle, you don't need an extensive assortment — you only need one bottle. This makes it particularly attractive for end customers who regularly maintain their vehicle themselves, without specific detailing background knowledge. Compared to the SONAX XTREME Car Interior Cleaner, the CleanStar scores with its ECOCERT certification and its explicit approval for piano black and touchscreens. The XTREME interior cleaner is more designed for stubborn everyday dirt without material restrictions, where the gentleness of the cleaning agent plays a less critical role.

Those who work in workshops or professional detailing and need larger quantities will find the SONAX PROFILINE CleanStar EcoCert to be the more economical alternative — identical formula, available in 5-, 25-, and 200-liter containers that can be filled directly in combination with a spray boy. For vehicles with particularly high-quality interiors — silk leather, exotic wood inlays, carbon trim, or special hard lacquers — the SONAX PROFILINE SensitiveSurface Detailer offers an even milder formula with a specific focus on highly sensitive surfaces where even a mild universal cleaner represents a calculated risk.

Conclusion of the comparison: The CleanStar EcoCert is not a specialist, but a reliable all-rounder. If you want to achieve optimal results for each material class, use specialized products. If you want to efficiently clean an entire interior without taking any risks, the CleanStar is an excellent choice.

Buy SONAX CleanStar — who benefits from the EcoCert interior cleaner?

The SONAX CleanStar EcoCert in the 750 ml spray bottle is the right choice for anyone who wants to completely clean their vehicle interior with one product — without compromising on sensitive materials and without sacrificing results. It is particularly suitable for vehicles with mixed interiors (leather + Alcantara + plastic + touchscreen), for owners of high-quality vehicles who do not want to take any risks when cleaning piano black or displays, and for anyone who values ecologically certified ingredients in cleaning products.

The 750 ml bottle is sufficient for many cleaning cycles with household use — it is ready-to-use, directly applicable, and requires no dilution. For regular detailers or professional businesses, the CleanStar in the PROFILINE canister is the more economical option. As an accessory, we recommend a soft, lint-free microfiber cloth with sufficient pile — avoid rough or worn cloths to prevent scratches on sensitive high-gloss areas. If you also want to condition the leather surfaces after interior cleaning, the SONAX PROFILINE LeatherCleaner is the ideal next step for a complete interior care program.
