Magma

Magma is designed to break down iron particles embedded in paint and wheels—brake dust, rail dust, and airborne fallout. Spray it on a clean, cool surface and watch it react visibly, turning purple where iron is present. It works on body panels, alloys, and glass, and rinses clean with a pressure washer or hose. It’s pH neutral, so safe for clear coats and sealants. Unlike clay bars, it doesn’t scratch or require manual rubbing. It’s especially effective on white or light-coloured cars, where iron spots are more visible. On wheels, it foams slightly and lifts grime without needing heavy agitation1 2 . ✅ Pros Colour transform tech—shows exactly where iron is breaking down Safe on paint and wheels—pH neutral, non-abrasive Mild scent—less offensive than typical iron removers Effective on first pass—often no need to reapply Preps surface for wax/sealant—smooth finish after use Can be used on glass—removes embedded particles ⚠️ Cons Not a clay substitute for tar—may need separate tar remover Avoid brake discs—can degrade surface if left too long1 Don’t apply in sunlight—can dry and leave residue2 Nozzle can clog—rinse after use Premium price—around £10–£12 for 500ml 🧍‍♂️ Personal Verdict Used this on a white Qashqai and alloy wheels—purple reaction kicked in fast, rinsed clean, and left the paint feeling smooth. For under £12, it’s a proper tool for deep cleaning before waxing or sealing.

Very good at removing iron from car paint. Works quick and is easy to use.

Great product, and it works. Thought I might have to cut and polish the rear of my car because of stubborn iron deposits and grime, but hey, sprayed on as instructions, left for a short time, turned purple, jet washed off and washed with car shampoo. Total delight.

I recently tried out the Autoglym Magma Liquid Clay on my car, and I must say it delivered impressive results. This product excels at removing stubborn marks on both the paint and tires, leaving my car looking refreshed and revitalized. I was pleasantly surprised by how effortlessly it tackled deep-seated contaminants, restoring the smoothness and shine of my car's surfaces. The Autoglym Magma Liquid Clay proved to be particularly effective at removing marks on both the paintwork and tires. Its specialized formula ensured that even the most stubborn blemishes and debris were lifted away, leaving a noticeably cleaner and more vibrant appearance. While the product performed admirably, I did notice a slight scent while using it. Although not overpowering, it is worth mentioning for those who are sensitive to certain odors. However, the overall performance of the product far outweighed this minor drawback. In conclusion, the Autoglym Magma Liquid Clay is a reliable car cleaner that exceeded my expectations. Its ability to effortlessly remove stubborn marks on the paint and tires is commendable, and the results speak for themselves. Despite the slight scent, I highly recommend this product to anyone looking for an effective solution to revitalize their car's surfaces.

AutoGlym Magma, A solid product that get rid of ingrained dirt of the bodywork and wheels. I personally just sprayed the solution on the panel or wheels and left to dwell for a couple of minutes before washing off. I would say this doesn't replace the liquid clay however, it does do the job its states and its pretty much effortless to use so to some its less effort and i was impressed with the results. I should state this is to be used after the car is cleaned. Overall a quick spray is all that's needed, i liked the results and felt it was good value.

One of the best products I have ever used. Some idiot used an angle grinder near my car and showered the wing with little flakes of metal that in bedded them selfs into the paint. A few days later I noticed little orange speckles in the paintwork where the metal swarf had started to rust. Two treatments with this and the rusty particles are totally gone without having to use abrasive methods and the paintwork is restored.

Never used iron fallout before but this seems to work well and gave my car a nice clean look, would be good if the bottle was a bit easier to use.

Ok to start off I was pretty sceptical. I had an issue where my car got covered with angle grinder metal sparks, needless to say I was not amused. It was pretty well stuck there and wouldn’t come off. I tried different things in non conspicuous areas to no avail. I heard of this and thought it can’t be as good as others say. Sprayed it on and let it do its thing and smack me in the head with a rotten fish it worked amazing. Paintwork is now spotless.

Di prodotti del genere ne ho provati tanti ma questo li batte tutti. Spruzzato su cerchi molto sporchi. Lasciato agire il tempo di passare la spugna su tutta l'auto e poi semplicemente risciacquato con idropulitrice. Perfettamente puliti. Mai più senza.

Does the job. Removed all rust spots in my car. Great thing about this product is it changes color so it easily visible to give a slight wipe on the rust spot areas. I recommend it!

Buen limpiador de coche para quitar el oxido pegado y demás cosillas que se quedan pegados en la carrocería del coche. Se pone rosa y luego se limpia bien.

Best rail dust and iron removal for your car. This product was discontinued in our local store. Trust this spray enough to work on my million dollar collection.

Perfect for cleaning, wheels specially and all the bugs that remains on your car after driving on the highway
