When I’ve applied a wax to the wheels, I haven’t noticed any real degradation to the wax after using this cleaner. One thing to note though is that there isn’t a fallout remover on it, so you’ll need to follow it up separately with one of them. Having said that, after using this on a particularly dirty set of alloys, I noticed that there wasn’t a substantial amount of iron fallout left behind. We were sent a 500ml bottle of Magma by Autoglym to put to the test. We have used it as part of the decontamination process on two vehicles both on bodywork and wheels and observed the effectiveness of contaminant removal and place for the product. Meguiar’s are keen to point out that this is more like a spray on, rinse off product and you don’t need to get the brushes out, but I would say you’re going to go through more of the product that way. When using it to clean your wheels, you will need to use brushes to agitate it and get rid of as much break dust as possible. I also like to use a separate wash mitt to get in behind the spokes on my alloy wheels to ensure that everything in there is cleaned. Again, a little goes a long way and it will light up your alloys like a Christmas tree. For those that are serious about detailing their wheels, Magma should be at the top of the list since it makes it extremely easy to remove any iron fallout. A pleasant smellA: Iron contamination can come from all sorts of places, but most often it is from vehicle braking. The brake dust that gathers around regular brake discs on your wheels is iron contamination. It is generated when the metal parts of your brakes are worn away during use. Trains that have stop at a train station will generate tremendous volumes of iron contamination, so if you park near a railway station regularly you will almost certainly have fallout on your car. Airports also generate fallout for the same reasons too, as well as industrial processes such as foundries, factories and iron works. Part of the Hybrid Solutions range from Turtle Wax is the rather excellent Hyper Foam Wheel and Tyre Prep. It works extremely well at both cleaning wheels and also giving a deep clean to tyre sidewalls as well (which is crucial before applying a tyre dressing).

Agitate bodywork with a soft damp sponge or wash mitt and agitate wheels with a brush or sponge before thoroughly rinsing off with water. Magma isn’t just a way to remove iron particles from your bodywork. It also doubles up as an excellent wheel cleaner. Personally, I prefer to use this as my go to wheel cleaner instead of buying a dedicated one. I do however have a dedicated wheel cleaner for the winter where there are large deposits of salt and grit on the wheels. When colour change function reacts no further, rinse with clean water ensuring all traces of Magma are removed Overall, the Auto Finesse Iron Out is a great fallout remover that’s safe, effective and affordable. The bulk buy options are also another great benefit as you can re-fill the spray bottle for even better value for the money. Those using more conventional formulas have also raised their game, and it has been interesting to see how they have matched the new generation in recent tests after a period of red domination.

In addition to this, it is pH neutral and therefore it isn’t going to cause any rapid deterioration to any waxes or sealants on the paintwork, regardless of how long they’ve been on for. This in itself if going to save you money since you don’t need to reapply coatings after using Magma. I’ve been using it for months now on top of a coating of UHD Wax and Magma has not impacted the quality of this coating. The colour change really helps to show the level of iron contamination on the alloys and it’s usually sufficient to only apply it to the wheels once. My recommendation is to apply it to cool wheels that are dry and leave it to work for 3-4 minutes. Not the most economical fallout remover. We used the entire 500ml bottle to cover two average sized vehicles bodywork and wheels. Not the cheapest to use. As is the case with the other two wheel cleaners, I recommend that this is used when the wheels are cool to the touch.
