My alloys had a year of brake dust and oxidation baked on. Diluted this at 1:5, gave it two minutes and rinsed - came out cleaner than I expected without any scrubbing.

Deep Decontamination
Strip years of build-up in minutes
Alumax cuts through what standard cleaners leave behind - heavy oxidation, ingrained brake dust and years of surface grime on aluminium and steel components. Its concentrated acidic formula gets to work in 1-2 minutes, leaving metal surfaces clean and ready for correction or protection.
Why Alumax
Built for the jobs that need real chemistry
Heavy-duty decon for metal surfaces where conventional cleaners fall short.
-
Acidic Decon Formula
Breaks down stubborn oxidation and ingrained grime that pH-neutral cleaners cannot touch.
-
Fast 1-2 Min Dwell
Works quickly so you can keep the job moving without waiting around between steps.
-
Flexible Dilution
Three dilution ratios let you match the strength to the severity, from heavy decon to light maintenance.
-
Workshop-Grade Yield
Concentrated formula stretches across large applications without compromising cleaning performance.
How It Compares
Alumax vs a typical all-purpose cleaner
Most detailers reach for an APC or pH-neutral wheel cleaner by default. Here is where Alumax earns its place alongside those products - and where the differences actually matter.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Removes heavy oxidation from metal | Yes | No |
| Effective on aluminium and stainless steel | Yes | Yes |
| Concentrated, adjustable dilution ratios | Yes | No |
| Safe on painted bodywork | No | Yes |
| Suitable for engine bay decontamination | Yes | Yes |
| Fast dwell time under 2 minutes | Yes | No |
Economical and Versatile
One product, multiple dilutions, serious yield
A single litre of Alumax diluted at 1:20 goes a long way, making it a practical choice for busy workshops and detailers who need consistent results across wheels, chassis and engine bays without burning through product on every job.

Solid acidic cleaner. The 1:10 ratio handles most of my wheel jobs without needing to go full strength. Just make sure your sprayer is acid-resistant before you start.

Engine bay on a customer's bakkie was genuinely bad - oil residue bonded with dust and grime for years. Alumax at 1:5 lifted most of it in one pass, rinsed clean.

Concentrate means it goes far. I've been using the 1:20 dilution for regular wheel maintenance between proper decon sessions and it keeps fallout from building up.

Decent descaler for the price per litre. The oxidation on stainless steel exhaust tips came off cleanly. Rinse thoroughly and follow with a neutral wash before any sealant work.

Three dilution ratios on one product makes this practical for a busy workshop - light maintenance jobs to full heavy decon without switching products. Packaged well, arrived quickly too.
Questions
Frequently asked
What dilution ratio should I use for heavily oxidised wheels?
For heavy contamination and oxidation, dilute Alumax at 1:5 (one part product to five parts water). For medium cleaning use 1:10, and for light maintenance or regular upkeep, 1:20 is sufficient and gives you excellent yield from each litre.
Is Alumax safe to use on aluminium wheels?
Yes, Alumax is specifically formulated for aluminium surfaces including wheels and aluminium trunks. Always dilute correctly and avoid prolonged dwell times beyond the recommended 1-2 minutes, then rinse thoroughly to prevent any potential surface reaction.
Can I use Alumax on painted surfaces?
Alumax is designed for metal surfaces such as aluminium, stainless steel, chassis and engine bay components. It is not intended for use on painted bodywork or clear coat. Keep it away from painted panels and rinse surrounding areas promptly if overspray occurs.
What sprayer should I use to apply Alumax?
Use an acid-resistant sprayer only. Standard plastic trigger sprayers can degrade with repeated use of acidic products. Dedicated chemical-resistant sprayers are widely available and essential when working with any acidic decontamination product.
How long should I leave Alumax on the surface before rinsing?
Allow Alumax to dwell for 1-2 minutes. You will typically see it working as it lifts contamination. Do not let it dry on the surface. Rinse thoroughly with water to remove all residue before moving on to any polishing or protective coating step.
Can Alumax be used in an engine bay?
Yes, Alumax is suited to engine bay cleaning and decontamination. Protect sensitive electrical components before applying, use the appropriate dilution for the level of grime, and rinse thoroughly. It is particularly effective on metal engine components with oil-bonded grime and oxidation.
Should I follow up with any product after using Alumax?
After rinsing Alumax, follow up with a pH-neutral wash or rinse to neutralise the surface before applying any polishing compound, wheel sealant or ceramic coating. This ensures the surface is properly prepped and that no acidic residue interferes with subsequent product adhesion.
Is Alumax suitable for industrial use beyond automotive detailing?
Yes, Alumax is formulated for both automotive and industrial applications. Its concentrated formula and flexible dilution ratios make it practical for workshops and industrial cleaning tasks where heavy metal decontamination is needed at scale.
