Fuego is a robust wheel cleaner that will melt away brake dust and grime, but also has iron remover in it.  It is a thick formula that clings to the wheel and paint instead of dripping off it to give better performance.  This 2 in 1 can be used to clean wheels and also decontaminate the paint.  Having one product that does multiple things will cut down on your cost of detailing products and time.  Life is short so cut down on detailing time to enjoy it.
