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

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.

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.

Managed to get two cars out of this. One car, which is white, had awful rust spots on it (super thin mazda paint!). This was able to get the majority of the spots out, but really needed to scrub to get them out. Wish it was a little stronger. I also found that that it dries incredibly quickly, which further makes this difficult or inefficient to use. On the whole, this was just as advertised and did a fairly good job.

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.

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

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!

Funciona de maravilla quita el oxido como dice sin esfuerzo.

Super efficace

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