No secret -- patience is the key ingredient. Sometimes I have it. Other times I don't. I try to walk away from my bike projects when I don't. I'm aware of some flaws in the refurbishment of the Stump that wouldn't be there if I had walked away a few minutes earlier!
The chemical bath was Evapo-Rust. http://www.evaporust.com/ Recommended to me by CyclArt. It helped remove the rust, but was not as magic as I hoped. But perhaps it set things up for the next step.
I then used a wire brush attachment on my Dremel tool to gently whir away remaining rust.
For polish I used two products: Simichrome and "Eagle One Never-Dull" and lots of elbow grease!
I could not use either the Evapo-Rust or the Dremel on the anodized parts. They took a lot of patience. I hate to tell you how many hours I've got into the handlebars and crankset! (Not to mention brakes, brake levers, rims, hubs, seat post, pedals, etc. etc. etc.)! It became clear that I would not be able to remove all the "frosting" on anodized parts without removing the anodizing too. So I polished as much as I could without removing the anodizing and simply have accepted the remaining stains as "patina".
I am still amazed at the results. Far better than I expected.
Hope that helps!
