I used it to remove iron deposits from the car's body. The car was white and had a very intense problem, to the point where it felt like it had a yellowish tint. During washing and drying, I was afraid that I might scratch it with all the "contaminants" it had. Sponges and cloths were constantly getting stuck on the deposits. I was ready to take it to a detailer for clay and whatever else it needed. While searching for various products, I stumbled upon this one and decided to try it. Its effectiveness was simply shocking! As soon as I applied it, the entire car turned purple. I used about 70% of the bottle and it removed the majority of the deposits. In other words, it removed about 80% of them with just one pass. The car is a family car, approximately 4.5 meters long. Since it was my first time using it, I also tried it on the wheels, even when they were dirty, and I used a larger quantity. I believe that even with such a severe problem, it wouldn't require more than 60% of the bottle. In any case, I will use the remaining product specifically on the areas where there are still some contaminants. It truly made the car white again and showed a different bodywork.

At around €18 that I bought it for, I wouldn't call it cheap, but I think it's definitely worth its price and I will buy another one for future use at some point. Just be careful not to leave it on plastic or rubber for too long as it may discolor them. Lastly, I don't think it can be effective if used on a dirty bodywork. Many people in YouTube videos suggested this method to prevent it from slipping off the surface and being wasted, but for me, it worked much better on a clean surface, which I find logical because when there is a layer of mud or any other material on the surface you want to clean, the cleaner cannot penetrate it in the same way.

Consistently the best iron remover for years...
Only the smell is unbearable for a long time.
Be careful not to let it dry on the bodywork because it is difficult to remove afterwards.
Especially on the wheels, it works wonders.

Unique cleaner for aluminum wheels. Removes almost all dirt. It is also suitable for the rest of the car if you want to remove iron deposits.

Good product, works properly, I have bought several products from carpro and the only problem I have is that the dispenser breaks almost immediately before it even reaches the middle of the bottle.
