I've read some information about IronX. I was thinking about picking some up soon, however I am confused about the use for wheels.. It said on the product description on AG that you should avoid spraying the brake Calipers, wheel balance weights ect. What I'm asking is would it do serious harm if used as a wheel cleaner. Because it seems unethical to have to mask off different parts of the wheel just to use it... Also where would an IronX application step fit in on a Wash clay Polish Wax?
