Autoglym Magma Liquid Clay, 500ml - Colour Transform Technology Bodywork and Wheel Fallout Remover, Removes Stubborn Iron Specks From Car Bodywork, Brake Discs, Car Wheel Cleaner

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.

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

Even after reading all the positive reviews I still felt skeptical going into using this product... was it really going to be THAT good?! But it was! I have recently purchased a VW Beetle that was bought from a garage located very near a railway line and was also off a busy road which also had a building site across from it. It was literally covered in little rust spots from iron particles and had quite a rough gritty feel to the paintwork. This product worked wonders and the paintwork now feels as smooth as silk. It removed the vast majority of the rust spots, a second use will be needed to get a few more stubborn ones, but overall it's changed the quality of the bodywork massively. I would highly recommend this product and will buy it again myself. Just note that if the product gets onto your skin it leaves an unpleasant smell which is hard to remove.

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.

Unbelievable product......couldn't believe how well this worked. I had a stubborn stain splashed all over my van that wouldn't come off with hot soap and water. Just spray this on, leave for 5 mins and rinse off. Done.

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.

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.

Does what it says on the tin, I found some very small rust dots on my van after it had been in the garage so had some home come into contact with some contaminants. Paint was rough to the tough. This stuff quickly identified all areas and help clean, didn’t lift all off so had to do some further cleaning but certainly worthwhile

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!

Funciona de maravilla quita el oxido como dice sin esfuerzo.

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 .

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