SONAX CleanStar "Ecocert" interior cleaner 750ml

Clean a whole interior, every surface at once — with the SONAX CleanStar EcoCert

What does the SONAX CleanStar EcoCert do? The all-in-one interior cleaner gets every surface in the cabin clean — from glass to Alcantara to the touchscreen display — streak-free, gentle on materials, and with ECOCERT Greenlife certification.

If you clean a car's interior regularly, you know the headache: one product for leather, another for plastic, a third for the glass — and the moment a delicate touchscreen or a piano-black trim panel shows up, cleaning turns into a guessing game. The SONAX CleanStar EcoCert solves that with a single bottle: a mild, ready-to-use spray that gets every material in the cabin clean, with no residue, no streaks and no risk of surface damage on the sensitive bits. On top of that comes the ECOCERT Greenlife certification — a mark of quality for detailers who care about what goes into their care products.

• One formula for every interior surface. Glass, piano black, fabric, Alcantara, leather, plastic, touchscreen displays — the CleanStar works on all of them with no streaks, residue or discolouration. You skip the constant switching between cleaners and move through the whole cabin faster and more methodically, without giving anything up on cleaning power.
• ECOCERT Greenlife certification for a clear conscience. The cleaner is certified by ECOCERT Greenlife to the ECOCERT standard — meaning the ingredients meet defined requirements for biodegradability and environmental compatibility. For detailers who care about product responsibility, or want to win over customers with a green quality promise, that's a real difference from conventional interior cleaners with no certification.
• An odour killer, not a perfume cover-up. The cleaner carries an active odour neutraliser that chemically breaks down unpleasant smells in the cabin — not just masking them with fragrance. After cleaning you're left with a pleasant, fresh scent that lifts the interior without feeling artificial or in-your-face. On cars with smoke or pet smells baked in, that's a difference you can actually notice.

Detailing1's tip from the shop: Always spray the CleanStar straight onto a microfibre cloth, never onto the surface — that keeps overspray off the neighbouring materials and gives you far more control over how much moisture goes down. On touchscreens and piano-black surfaces work with minimal pressure and follow up straight away with a dry, clean cloth. For stubborn upholstery grime, rinse the cloth out with clean water now and then and re-spray — repeat until the cloth still looks clean as you wipe. That way you never rub dirt you've already picked up back into the surface.

An interior cleaner for every surface — how the CleanStar's universal formula works

Most interior cleaners are tuned for one class of material: either plastic, or glass, or textiles. A true universal cleaner has to work on wildly different surfaces — from smooth, water-repellent glass and piano-black panels through porous textiles and upholstery to delicate microfibre materials like Alcantara. The SONAX CleanStar EcoCert pulls that off with a mild, pH-neutral formula that lifts dirt without swelling, bleaching or leaving residue behind.

The basic idea: the cleaner breaks the bond between dirt molecules and the surface, so you lift the loosened dirt off with the microfibre cloth instead of rubbing it deeper in. On absorbent materials like fabric or Alcantara, the streak-free drying formula stops water rings — a common problem with cleaners that carry too much surfactant and leave white rings or marks as they dry. On non-absorbent surfaces like glass or high-gloss plastic, the leftover moisture flashes off cleanly, so you get streak-free results even without a heavy second wipe.

The ECOCERT certification isn't only about the green side — it's also an indirect signal about the formula itself: certified surfactants and ingredients have to meet set biodegradability and compatibility standards, which by the same token means the harshest or hardest-to-break-down chemicals are ruled out. That lowers the risk of unwanted reactions on sensitive materials — which helps explain why you can use the cleaner on so many different surfaces without specific compatibility checks.

An interior cleaner for touchscreens and piano black — what sets this one apart

Sensitive areas like infotainment touchscreens, high-gloss piano-black trim and matte-lacquer surfaces call for extra care. Harsh cleaners can leave micro-damage on these: touchscreens lose their oleophobic protective layer and get harder to operate, piano black shows fine wipe marks or hazing, and matte surfaces pick up unwanted glossy spots where you rub. The CleanStar is explicitly cleared for these surfaces — the formula is mild enough that it doesn't attack protective layers or change the character of the surface.

With touchscreens and piano black, the application technique matters as much as the product: little moisture on the cloth, minimal pressure, no circular rubbing — straight wipes parallel to the surface instead. On piano black, go for a single pass with a soft microfibre cloth, followed by a dry buffing or glass-polishing cloth. On mirror-like touchscreen displays the result comes out streak-free, as long as the cloth itself is clean and free of coarse particles — a grubby or linty cloth is the most common cause of scratches on displays and high-gloss areas, not the cleaning product.

The CleanStar is especially handy for modern cars, where touchscreens on the dashboard sit alongside plastic trim, leather panels or aluminium inlays. Instead of keeping several products within reach and swapping every time the material changes, you work the whole cockpit with a single cloth and one bottle — that saves time and cuts out the classic mistake of putting the wrong product on the wrong surface.

An interior cleaner for Alcantara, leather and plastic — where it earns its keep

A modern cabin is a mix of materials: dashboard and door cards in hard plastic or soft-touch lacquer, seats in fabric, leather or Alcantara, headliner in textile, centre console in piano black or aluminium look. Add in rubber seals, carpet, steering wheel and gear knob — every material has its own surface and its own sensitivity. The SONAX CleanStar EcoCert covers all of it, so you can run a full interior pass without switching products.

On leather, the cleaner pulls off surface dirt, greasy build-up and light stains without stripping the natural moisture out of the surface. That said: cleaning is no substitute for leather care. After cleaning with the CleanStar it makes sense to follow up with a SONAX PROFILINE LeatherCleaner or a leather conditioner, to put moisture back and keep the leather supple over the long run. Clean leather hard and then skip the care, and over time you're risking it drying out and cracking.

On Alcantara, the cleaner lifts grease spots, light everyday grime and odour particles without damaging or matting down the signature velour pile. The key when working Alcantara: always use little moisture and wipe in one even direction (following the pile), never rub in circles. After cleaning let it dry briefly, then brush the pile back up if needed with a dry, soft cloth or a soft brush to restore the texture. For deeper grime or stains that don't fully lift on the first pass, a second go or a dedicated upholstery stain remover may be needed.

On hard plastics, rubber surfaces and carpets the cleaner shows its strongest side: here you can lay it on with a bit more pressure and a bit more moisture, with no risk to the surface. On heavily soiled carpets or floor mats it pays to let the cleaner dwell for a moment (30–60 seconds) before you go in with the cloth — that gives it time to loosen the dirt before you lift it off.

Comparison: CleanStar EcoCert vs. other interior cleaners

Next to specialised products the CleanStar has one clear edge: if you want to fully clean a car's interior, you don't need a big line-up — you just need one bottle. That makes it especially appealing for end customers who care for their car themselves, without any specific detailing background. Against the SONAX XTREME interior cleaner, the CleanStar scores with its ECOCERT certification and its explicit clearance for piano black and touchscreens. The XTREME interior cleaner leans more towards stubborn everyday grime with no material limits, where how gentle the cleaner is matters less.

If you work in a body shop or pro detailing setting and need bigger volumes, the SONAX PROFILINE CleanStar EcoCert is the more economical route — identical formula, available in 5, 25 and 200-litre containers that decant straight through a Sprayboy. For cars with really high-end interiors — silk leather, exotic wood inlays, carbon trim or special hard lacquers — the SONAX PROFILINE SensitiveSurface Detailer offers an even milder formula built specifically for highly sensitive surfaces, where even a mild universal cleaner is a calculated risk.

Bottom line on the comparison: the CleanStar EcoCert isn't a specialist, it's a dependable all-rounder. If you want the best possible result on every single material class, reach for the specialised products. If you want to clean a whole interior efficiently while risking nothing, the CleanStar has you covered.

Buy the SONAX CleanStar — who is the EcoCert interior cleaner for?

The SONAX CleanStar EcoCert in the 750 ml spray bottle is the right pick for anyone who wants to fully clean their car's cabin with one product — no compromises on delicate materials, no cutting corners on the result. It's a particularly good fit for cars with mixed interiors (leather + Alcantara + plastic + touchscreen), for owners of high-end cars who don't want to take any chances cleaning piano black or displays, and for anyone who values ecologically certified ingredients in their cleaning products.

The 750 ml bottle lasts for plenty of cleaning passes in everyday use — it's ready to use, goes on straight from the bottle and needs no dilution. For regular detailers or professional outfits the CleanStar in the PROFILINE canister is the more economical option. As a companion accessory we'd recommend a soft, lint-free microfibre cloth with plenty of pile — keep rough or worn cloths away to avoid scratches on delicate high-gloss areas. If you want to condition the leather surfaces after the interior clean, the SONAX PROFILINE LeatherCleaner is the ideal next step for a complete interior care routine.
