Magma, Iron Fallout Remover, 500ml

I bought this Autoglym Magma liquid clay as a first step in spring cleaning the cars paintwork. Now I have to be honest and I fully expected to have to clay bar after use but I can highly recommend this product. It is far easier than I thought, also it worked far better than I imagined. It foamed well with the wash mitt removed contaminants with ease and left the paintwork with a smooth shine. I did follow up with a wax so I can highly recommend Autoglym Magma liquid clay as a product although it took a little more time to rinse off. Definitely worth a try before you try a clay bar.

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. 😃

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.

Perfect

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.

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.

It stinks but it gets the job done

Genial!! Es lo que esperaba. No había forma de quitarlo, probé con todo, milagrito, sisbril, desengrasante, incluso KH7 (ojo con este que quita el brillo). Pero este producto logró disolverlo y quitar esas pintitas naranjas de óxido.

Very easy to use. would've been hours with a claybar to remove the rust spots. This stuff melted them away in minutes. A bit expensive, but works incredibly well! With 2 white cars on the driveway, this stuff is a must.

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!

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 !
