There are much cheaper options for the same job. It should also be mentioned from the start that it is not suitable for motorcycles. I don't know why, but it is mentioned on the label nowhere in the description.

Excellent product. You see, due to a chemical reaction, the iron immediately breaks down. See for yourself. https://youtu.be/B2WdeZINyKw?si=Upm5GIRLy4GAX2w6

I used it on wheels and bodywork of a 20-year-old car, permanently parked outside and with damaged paint. As soon as I applied it, the whole car turned purple. As the instructions say, you leave it for 3 to 5 minutes and then rinse with plenty of water. I finished a whole bottle and I estimate that I will need another one to remove all the iron particles that have been stuck all these years. For use before clay and polishing, it is an essential product for me.

Fantastic product and it does what it promises. My white car was filled with purple stains everywhere the moment I applied the product on the entire bodywork and it started to work. After 3-4 minutes, I rinsed it well with water and the car finally cleaned up and enhanced its color even more. It leaves a very pleasant smell and I highly recommend it for use 2-3 times a year, especially for those who park their car exposed. Using a generous amount of product, it lasted me for 2 times on a 5-door hatchback. There were black stains on the car that wouldn't come off with regular washing and there were pollutants embedded in the varnish, making it look unwashed. All of that disappeared. It was also used on a motorcycle without soap washing. I simply applied the product and the bike shined. Effortlessly, without hassle or rubbing. Considering its price and quality, I consider it an excellent choice. It didn't damage any part of the car.

Excellent product, it does an incredibly good job!
Very easy to use and in combination with clay, the result is elevated! I used it in white color and it fully stood out!

Do you have flashy wheels in a light color that get dirty from brake dust? Look no further!

Seriously though, there shouldn't be more than two other products out there that do what this one does with such ease.

Magma is one of the three wheel cleaners from AutoGlym. This one not only removes brake dust but also is safe for the car's paint to remove residue from the color.

For cold wheels:
- Shake the bottle
- Wet the wheels a little
- Spray three to four times
- Wait for 2 minutes. While you wait, you can see the iron and brake residue being removed.
- Clean with a brush
- Rinse with water and they're ready

You can do the same for the bodywork (without the brush!). If you forget to rinse it off and it dries on the bodywork, it will leave a white residue, but it hasn't caused any damage on plain or metallic colors for me. Just wet it and clean it with a cloth.

Seriously, it's the best thing out there!
