I treated the rusty steel rims and galvanized spokes on my '73 recently to great results. The spokes developed a chalky, white layer, but it comes off easily with a nylon brush. It's easier if you brush the white layer off every few hours. I will try and update this post with pics.
I use wood bleach crystals with hot water. I don't measure the crystals as I have not found it necessary.
