German paint-correction chemistry, OEM-approved by Mercedes-Benz and BMW — stocked by a chemistry-driven Melbourne workshop.
Alpha Details is an authorised Koch Chemie reseller in Australia. We stock the active Koch range — the H/M/F compound system, GSF and AF wash chemistry, Reactive Wheel Cleaner, Plast Star Siliconölfrei — from our Heidelberg West Melbourne studio with Australia-wide shipping.
Where Koch Chemie fits in Australia
Koch Chemie is the German professional car-care manufacturer behind some of the most respected paint-correction and wash chemistry in the trade. Manufactured in Unna, Westphalia since 1968 and endorsed by the in-house service operations of Mercedes-Benz and BMW, the range is built around chemistry that is precise, repeatable, and engineered for a working detailer's bench.
Koch-Chemie Oceania is the official distributor for Australia and New Zealand at kochexperts.com, supplying the authorised reseller network. Major Australian stockists alongside Alpha Details include Waxit Car Care, The Detail Store and Car Supplies Warehouse. The combined network covers the country well, but each reseller curates a different slice of the catalogue.
We carry the Koch products we actually use on customer cars in our workshop — the H/M/F compound system, wash chemistry, decontamination, interior care and the silicone-oil-free trim dressings — rather than the full SKU library. If you want a workshop-curated Koch range from a chemistry-driven Melbourne stockist, we are a good match. If you want the entire Koch catalogue including specialty tradesman SKUs, the official Oceania distributor is the wider source. There's room for both.
Why detailers reach for Koch Chemie
A correction system, not separate products
H-series · M-series · F-series
Heavy Cut H9.01 removes weathered clearcoat damage, sanding marks and serious oxidation. Micro Cut M3.02 finishes streaks, holograms and fine scratches to a near-flawless surface. F-series Fine Cut polishes the result to a true mirror. Grain sizes step down predictably; carrier oils are formulated to cooperate so a follow-on pad does not contaminate. Works equally on hard German clearcoats and softer Japanese paint.
OEM-approved chemistry
Mercedes-Benz & BMW endorsed
Koch Chemie is approved by the in-house service operations of Mercedes-Benz and BMW. The chemistry has passed OEM substrate compatibility testing on actual factory paint and trim — not just internal lab tests. When the dealership service centre uses the same product on a warranty repair, you can be reasonably confident it isn't eating the clearcoat.
Reactive iron-removal
No hydrofluoric acid · pH-neutral
Koch's Reactive Wheel Cleaner is pH-neutral and chemistry-driven: a thiol-based active ingredient binds iron particles and changes colour to indicate the reaction is complete — without hydrofluoric acid or ammonium bifluoride. The visual indicator is genuinely useful in a workshop because you know when the product has finished doing its job. Safe across coated paint, PPF, brake calipers and uncoated alloy.
Silicone-oil-free trim chemistry
Plast Star (PSS) Siliconölfrei
The dressing we reach for on exterior plastic and rubber trim. The silicone-oil-free formulation does not migrate onto adjacent paint, does not interfere with later masking and adhesive jobs (PPF, vinyl, paint correction tape), and does not leave the slick film that traps dust. Restored trim without contaminating the rest of the workshop.
Authorised · Workshop · Trainer
An authorised Koch Chemie reseller running the chemistry every day — in a Melbourne workshop and an OEM service team.
Alpha Details is an authorised Koch Chemie reseller in Australia, based at Heidelberg West, Melbourne. We use Koch Chemie wash and paint-correction chemistry on customer cars every day — both for studio coating preparations and retail-grade detailing. Our preferred Koch tools sit alongside Labocosmetica and Feynlab in the same workshop, because each brand is genuinely better at different parts of the workflow.
Paolo Recinella runs Alpha Details. He holds an industrial chemistry degree with majors in both organic and inorganic chemistry. We treat Koch's compound chemistry as the abrasive-and-binder system it actually is: grain hardness, lubricant phase, working time, and how the residue behaves between pads. That perspective is why we use the H/M/F system rather than mixing-and-matching across brands mid-job.
Alpha Details delivers car-care training to the Porsche Doncaster service team. The chemistry detail we apply on a customer car is the same detail we teach into the OEM service workshop — which keeps the standard high.
The Koch Chemie range we carry in Australia
Workshop-curated — the Koch products we actually use on customer cars, available for same-day Melbourne dispatch and Australia-wide shipping.
Wash chemistry
GSF · AF · QS
Gentle Snow Foam (GSF) — the pH-neutral pre-wash for coated paint and PPF. Active Foam (AF) — the mild-alkaline counterpart for heavier traffic film and bug residue. Quick & Shine (QS) — the spray-and-wipe quick detailer for between-wash maintenance.
Decontamination
Reactive WC · ASC · MZR
Reactive Wheel Cleaner — pH-neutral colour-changing iron remover for wheels, calipers and bonded paint contamination. Allround Surface Cleaner (ASC) for general workshop and vehicle cleaning. Mehrzweckreiniger (MZR) for heavier alkaline jobs — road grime, soot, engine residue.
Paint-correction system
H-series · M-series · F-series
Heavy Cut H-series compounds for serious clearcoat repair, Medium Cut M-series for one-step and two-step correction, F-series Fine Cut polishes for finishing. The Koch system is what you reach for when consistency between sessions matters more than chasing single-product hype.
Interior & trim
PO · LS · PSS · MP
Pol Star (PO) for textile, leather and Alcantara — the workshop pick that doesn't leave wet residue. Leather Star (LS) and Protect Leather Care for leather conditioning. Multi Interior Cleaner. Plast Star Siliconölfrei (PSS) for exterior plastic and trim. Motorplast (MP) for engine-bay conservation. Speed Glass Cleaner for streak-free glass.

What makes Alpha Details different
Paolo Recinella runs Alpha Details. He holds an industrial chemistry degree with majors in both organic and inorganic chemistry — unusual in the detailing trade, where most operators come from automotive backgrounds. We treat Koch Chemie's compounds as the abrasive-and-binder chemistry they are: grain hardness, lubricant phase, working time, residue behaviour between pads.
That chemistry depth is why we are an authorised Koch Chemie reseller, the certified detailer running Labocosmetica training sessions for Porsche Doncaster, and a certified installer and trainer in the Feynlab professional ceramic coating range. Other detailers in Melbourne send their cars to us when a job demands chemistry expertise rather than glove-and-go labour.
Worth knowing →
Many "acid-free" wheel cleaners on the market still rely on hydrofluoric acid or ammonium bifluoride at the active end. Koch Chemie's Reactive Wheel Cleaner is genuinely pH-neutral and uses thiol chemistry instead — which is why it stays safe on coated wheels, PPF and uncoated alloy across repeated use. The colour-change indicator is a workshop convenience, not a marketing gimmick.

Frequently asked questions — Koch Chemie in Australia
Where can I buy Koch Chemie products in Australia?
Koch Chemie is supplied to Australia through Koch-Chemie Oceania, the official distributor at kochexperts.com. Major authorised resellers include Alpha Details (Melbourne), Waxit Car Care, The Detail Store and Car Supplies Warehouse. Alpha Details stocks the products we use on customer cars — paint correction, wash chemistry, decontamination, interior care and silicone-oil-free trim — at our Heidelberg West Melbourne studio with Australia-wide shipping.
Why do professional detailers prefer Koch Chemie compounds?
Koch Chemie's compound range is laid out as a system: H-series for heavy cut, M-series for medium correction, F-series for finishing. The grain sizes step down predictably and the carrier oils cooperate between pads. Works on both hard European clearcoats and softer Japanese paint. Predictability between stages is what most working detailers value — same lubricant phase across pads, no surprises mid-job.
Is Koch Chemie endorsed by car manufacturers?
Yes. Koch Chemie is approved by the in-house service operations of Mercedes-Benz and BMW, which means the chemistry has passed OEM substrate compatibility testing on factory paint and trim. Many German dealership service workshops use the Koch Chemie range as their default car-care chemistry.
GSF vs AF vs Auto Shampoo?
Gentle Snow Foam (GSF) is pH-neutral — a pre-wash for coated paint, PPF and routine maintenance washes, gentle enough to use weekly. Active Foam (AF) is mild-alkaline for cars carrying heavier traffic film, bug residue or seasonal grime where pH-neutral isn't enough. Auto Shampoo (AS) is the contact-wash shampoo for the two-bucket method, formulated for cleaning power without stripping wax or coating.
Is Reactive Wheel Cleaner safe on coated wheels?
Yes. Reactive Wheel Cleaner is pH-neutral and uses a thiol-based reactive chemistry that binds iron particles and changes colour to indicate the reaction is complete — without hydrofluoric acid or ammonium bifluoride. The pH-neutral formulation is safe on coated paint, PPF, brake calipers and uncoated alloy. Unlike acid-based wheel cleaners, repeated use does not progressively damage the substrate.
What does "silicone-oil-free" mean on Plast Star?
Silicone oils in trim dressings migrate. They creep onto adjacent paint, contaminate masking tape, interfere with PPF and vinyl adhesion, and leave a slick residue that traps dust. Plast Star Siliconölfrei (PSS) is formulated without silicone oils — it restores trim colour and provides dust-shedding hydrophobics without contaminating the rest of the vehicle or workshop.
Can I get Koch Chemie shipped Australia-wide?
Yes. Alpha Details ships the Koch Chemie range Australia-wide. Most orders dispatch same-day from our Heidelberg West Melbourne studio. Concentrated chemicals and larger pack sizes ship under standard freight conditions; some restricted SKUs require a signature on delivery.
Koch Chemie vs Labocosmetica vs Feynlab?
Koch Chemie's strength is the paint-correction compound system (H/M/F) and OEM-grade wash chemistry — the workshop bread-and-butter where consistency between jobs matters most. Labocosmetica's strength is the integrated 3-pH wash and decontamination system with VDA certification across substrates. Feynlab's strength is surface-specific coatings and the Heal-range memory-polymer self-healing chemistry. Most working detailers carry products from more than one of these brands — we retail and apply all three.
