Iron/Fallout Decontamination

[Avant_Garde]

So I just recently got delivery of a white '22 S4. After its first wash, I noticed quite a few iron spots and other clear coat contamination throughout the car. At first I was a bit worried, since I only owned the car for a few days at that point. After doing some reading, I came to realize this was common, especially on white cars. Most of this could be from the rail, although some was from breaking in the new brakes as well I assume.

I recently purchased Iron X which I plan to use to remove all this contamination and fallout. The way I normally wash my car is I first use a rinseless pre-wash (McKee's N914) with an iK Multi-Pro sprayer. Let that sit, then rinse off. Then use a foam cannon to coat the car, microfiber wash mitt to clean, then rinse off. Before drying, I then spray the whole car with P&S Beadmaker, then dry using a Rag Company Gauntlet drying towel.

My question is, can I use the Iron X prior to doing all this? After a bunch of reading and research on using chemical decontamination, it seems like most people spray the car post-wash and pre-dry. So in my case, before I spray the car with the P&S then dry, I would spray the car with Iron X, let sit for 3-5 minutes, rinse off, then go about my business.

Would it be ok to start with the Iron X instead? In my case, I would still perform the pre-rinse method to get rid of most of the dirt, then rinse. Now, instead of using the foam canon like I normally would, could I use the Iron X at this stage then continue to wash the car like normal? Or, in the case of a rinseless wash, pre-rinse with McKees > let it sit > rinse with water > Iron X > let it sit > rinse with water > then one more round of McKees > P&S > dry. Is this a viable option as well?

Sorry for the long winded post, just waned to make sure I got all my steps in for both wash methods. TIA

I would use the Iron X after your pre-wash and then rinse off then start the wash.

You may consider diluting the Iron X in whatever ratio you prefer as well, if you plan on using the Iron X every wash.

This is exactly what I was looking at doing. Pre-wash/let it soak, rinse, then Iron X/let it soak, then wash the car.

Any other iron removers that people recommend? I’m considering the Adams or the Megiuars Detailer line.


OP, I’ve always pre washed with foam cannon and quick hand wash, then iron decon, clay and final wash. After that I spray prep spray to remove polishes and then compound or polish before coating.

I always do pre wash and wash before iron decontamination or clay.

In your case. I would iron decontaminate, clay and do a light polish before protecting.

Like above I pre-wash and decon sections of the vehicle at a time, you don’t want the decon to dry on the car.
I decon once a year, a good quality top coat will minimize the iron spots

I've had success with Bilt Hamber fallout remover but more recently I've tried Simoniz Iron Active Wheel Cleaner - clear liquid in a hand spray, turns purple on the spots it lifts off. Can be used on all paintwork/glass and is acid free. Best part is in the UK its upwards of £5 / 500ml.

I use 3D iron remover. Ive tried a couple different ones over the years and found that 3D products are good for a amateur detailer.
