Put a stop to premature corrosion with the CARPRO IronX. It’s safe, effective, and is suitable for all vehicle surfaces, including gloss paint, wheels, glass, chrome, and more.

So, I sprayed this on the wheel and waited for 5 minutes. Let me warn you – the smell is a little bit intense, so I would recommend applying it somewhere in an open space. I rinsed the rim, and around 98% of brake dust was gone with no effort. I was impressed and decided to give this remover one more check. There was an iron stain from under the rear hatch window, and I couldn’t get rid of it with clay. The CARPRO IronX did a fantastic job and removed naughty iron particles from the hard-to-reach place.

The CARPRO IronX is the best iron remover as its pH neutral and delivers excellent iron decontamination properties to most vehicle surfaces.

I used this product in the garage and noticed only a subtle scent. Compared to CARPRO IronX, you need more of the product to get the same job done. So, even though it comes in a large bottle – 35 oz (1,035 ml), you won’t see the size difference.

Gtechniq W6

Gtechniq W6

The Gtechniq W6 iron remover offers the easiest and safest way to fight fallout and brake dust found on your vehicle’s paintwork and rims.

Similar to Griot’s Garage, this 17 oz (500 ml) iron remover has a thick and gel-like formula that clings to any surface, even the vertical one. But unlike other products on the list, this one has a corrosion inhibitor to combat the effects of acid rain.

The product comes with a sprayer, which I found inconvenient. The spray handle is too small for long-time use. Also, you’ve got to apply more of the product to get good coverage due to the liquid thickness.

It is also not as effective as other iron removers from my list. It copes with fresh contaminants but won’t handle stubborn, old brown spots on your car’s painting.
