I am going to try out Yoshimura Stain Magic and see what that does. I have quite a lot of blueing on my headers right next to the head. I have been real pleased with the longevity of Optiglanz. It does a great job removing soiling from headers.
I suspect a lot of the issue is with single wall headers.
