I saw the post about Windex, so I went out and tried it on my ZHP (Which has the wheels you love to hate part II, part I was the basket weaves on E30s) and the grime just melted away and wiped off. Since Windex is basically water/ammonia/isopropyl alcohol/food coloring...I think ammonia or alcohol may be the way to go. Going to try it next wash, diluted of course. I've also used kerosene with some success, it's pretty benign and won't hurt anything (Like your paint). De-natured alcohol also got latex paint off my car with no damage to the surface...so there's another choice.
