Yes the purple aspect is cool but you can actually see the cleanliness difference at the end. Great for the brake pads. It doesn't mean you don't need to put some elbow grease into the rims to get the dirt off but this makes life a lot easier.

It has strong cleaning performance, and you can see how much of dust turn to purple, however it is pricey (price is close to professional product), and also I saw it stained on the disc brake at few cars I detailed.

The wheels on my Renault Megane were filthy, especially the front ones. I bought this stuff after checking You Tube and looking at reviews. It worked just like it shows on the videos. Spray on, wait a minute till you see a dark pinkish flow, then pressure wash it off. Only had to do it once. I was amazed and very satisfied. This product does what it says. Don't vacillate, just buy some.

This product is some sort of sorcery. Probably one of only a few products that talks a big game and follows through with goods. It's also Australian so that's a plus.

It's not often that you can get a wheel cleaner, spray it on, hose it off and you're done. But that's often the case with this.

The purple bleeding with the reaction to the iron is amazing, as you can see it working.

The smell though... even the second generation, be careful.

This product is excellent. It does exactly what it says on the product description. Spray generously on your wheels where you see the brake dust, leave it for 1 to 2 mins for the product to activate and react with the brake dust. It will take all dust out by itself. It doesn't require any agitation by wheel brush too. This is for light to medium brake dust on the wheels.

I will recommend this product to all who want their wheels clean and shiny!

My son purchased this for his performance car which attracts a lot of brake dust. Started to work right away (you can literally SEE it working) and after a quick brush with a soft wheel brush, his wheels came up as good as new. Needless to say, I'm now using it on my car. This is a fantastic product. Shame I can't give it more than 5 out of 5.

I used this product in 2 of my cars (8 wheels), and it was fantastic. The magic happened after a minute waiting time. It cleans all the dirt and tyre grime. I'm recommending this product to everyone.
