Review: Iron fallout remover with colour change. Safe, effective, and prep-ready. - 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.

## Questions & Answers

**Q: What if your car is red???how do you see it then ??**
A: It turns a purple colour and you will see it on any colour car as it run but don’t let it dry before hosing it off and don’t forget it’s not as good as using a clay bar and may have to use the clay bar for stubborn areas.

**Q: Can i use this as clay bar lube**
A: Use before the clay it will make it much more easier and improve the clay process. But it wouldn't be suitable to use as lube. It will react with any iron on the body work and start drying... Rather then lubing.

**Q: Will this take chemical and hard stain marks off?**
A: Unfortunately no, Magma has been designed to remove stubborn specks of iron from paintwork and wheels  for a spotless silky smooth finish.

The active ingredients in Magma will turn purple as they react with these iron particles to safely loosen them and the reaction will occur if there are iron particles present.

**Q: Has anyone tried using this to remove rust spots from a block driveway?**
A: Hello, we can confirm that the Magma has only been tested for use on automotive surfaces and we could not guarantee compatibility or results if used for this reason 

We are sorry we could not have provided a more positive response on this occasion 

Kindest Regards

### ⭐⭐⭐⭐⭐ Good Product
*by J***T on 23 November 2025*

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

### ⭐⭐⭐⭐⭐ It really works!
*by K***Y on 7 August 2024*

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.
