Dean,

There's a product called Evapo-Rust that removes rust and coverts the surface layer of the steel to a more stable form of iron oxide.

http://www.evapo-rust.com/

Check out CR member Don Gilles' Carlton clean up with Evapo-Rust:

I've used it myself and it takes a little longer than the advertised time for good results.

Manually remove excess rust with a weapon of choice - steel or bronze wool, a wire brush etc. Put the rusted parts in a container with Evapo-Rust and let it sit for a while. For heavy rust it might take overnight. When done theres a black coating of carbon on the rusted areas that is easily washed off with water and a soft brush.

For removing ubiquitous rust around brake cable braze-ons on the top tube, I take a dental pick and gently remove any loose rust then stick a Q-tip dipped in Evapo-Rust into the cable guide. I have to cover them to keep the stuff from evaporating and reapply it several times time for heavy rust but it works. It can take a day or longer.

There are also some other similar products on the market.
