How to Get Rid of Iron Fallout and Brake Dust (Mar 2026)

Park the car under a carport or wait until the arvo. If the panels are hot to the touch, the chemicals will dry too fast and leave stains. I've seen a mate ruin a set of satin black wheels by spraying them while they were hot from a highway run, don't be that guy.

Give the car a thorough wash with your two-bucket method. We want to remove the loose grit, red dust, and bird droppings first so the iron remover can get straight to the metal particles.

I reckon the product works better on a dry or slightly damp surface. If the car is dripping wet, it dilutes the chemical and it'll just run off onto the driveway before it can do its job.

Wheels are always the filthiest part. Spray your iron remover liberally across the wheel face and inside the barrels. It'll start turning purple almost instantly.

Use your wheel brushes to stir up the purple 'bleeding' effect. This ensures you're reaching the stuff tucked behind the spokes.

Don't let it dry. Blast it off with the pressure washer until the water runs clear.

Working one panel at a time (start with the boot or roof), mist the iron remover over the paint. You don't need to drown it, just a light, even coat.

Wait about 3-5 minutes. You'll see little purple streaks running down the car. That's the chemical reacting with the iron. It's actually pretty satisfying to watch.

If the car is really bad, I'll sometimes take a damp, clean microfibre and very gently wipe the panel while the product is on there. No pressure, just enough to move the chemical around.

Give the whole car a massive rinse. And when you think you're done, rinse it again. Pay attention to window seals, door handles, and fuel caps where the product likes to hide.

Run your hand (inside a plastic sandwich bag) over the paint. If it still feels like sandpaper, you might need a second hit or a clay bar treatment.
