I'm trying to clean up my wife's Alpine White X5. In the first picture you can see tiny little spots that looks almost like rust and then the second picture shows where the white bumper has turned to off-color. It's a diesel, so it could be soot/carbon
Going over with a clay bar didn't work. Used Meguiars ultimate compound (applied by hand don't have a polisher) that didn't work either.
I've ordered a bottle of IronX, but not sure if that will take care of this.
