Magma, Iron Fallout Remover, 500ml | Colour-Change Fallout Remover for Bodywork & Wheels – Dissolves Stubborn Iron Contamination with Easy-Spray Application

Excellent product. Bought a second hand car and the wheels were in a mess. Gave all the wheels the Magma treatment, the front wheels needed 2 goes as they were bad, but the results were excellent, I also did the body work as the car is white, I couldn’t believe the difference, I washed it after with Autoglym ceramic wash, and it looked like a new car. Very happy. 😃

Great product for use on alloys. Can see when it reacts with brake dust. Cleaned up the wheels really well. Only minor point is it stinks.

Amazing quality product; I’ve used it for years and it always gives great results.

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.

Absolutely awesome bit of kit. I can’t believe I’ve never used this before.My car has come up a treat

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.

Used the Magma after a standard car wash and it performs exactly as described. Once sprayed on, it reacts visibly with iron particles, changing colour—this was particularly noticeable on the wheels where brake dust build-up was present. After rinsing, the wheels looked significantly cleaner, and even the brake discs appeared much fresher, almost like new again. Application is simple and the visual reaction makes it easy to see where it’s working, which is reassuring for a beginner. Overall, a very effective iron remover that does what it claims and delivers a noticeable improvement in wheel and body cleanliness.

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.

Super efficace

Il prodotto funziona in modo eccellente, come quasi tutti i prodotti Autoglym. Certo costa il doppio degli altri ma il risultato non ha pari se lo paragono ai precedenti. Consiglio di utilizzarlo nei lavaggio con la lancia che spruzza acqua. Prima si deve lavare l’auto, poi si spruzza per bene il prodotto, si aspetta 5 minuti, appare il colore viola e poi con la lancia ad acqua si toglie tutto. Meglio mettersi occhiali protettivi. La carrozzeria diventa liscia come si fosse passato il polish .

Vraiment efficace, Des la première utilisation vous savez que vous avez un vrais produit honorable et professionnel entre les mains ! Je recommande sans forcer !
