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

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.

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.

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

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.

All autoglym products I have bought have been excellent easy to use great price value for money recommend these for your vechicle

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

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.

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.

Very rarely do I give a 5 star rating to any product because products are rarely perfect. However, within minutes this spray removed all of the tiny brake dust rust specks on the paint on a white car. Follow the instructions.

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.

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