How do I remove rust from my seat tube? I just pulled my seat out as the first step of breaking my bike down for winter storage, and found that rust has formed between my seat tube and my seat post. The rust starts maybe 3" down the tube and continues for perhaps 4 more inches.

Is there anything I can do to remove the rust from the tube and post? What steps can I take to prevent it from reforming?
You can probably use a small wire brush to get the rust out of the frame and for the future use JP Weigle Frame Saver spray. It acts as a rust inhibitor so should slow down/stop any rust forming on the inside of the frame. You can get frame saver at JensenUSA (I'm sure there are lots of other spots too).
