Great post. Some years ago I used some wood bleach aka oxalic acid for an old Mongoose BMX frame and although it removed most of the rust, I didn't realize I had to spray it down with a rust protectant / WD40 to prevent flash rust so it needs to be done again, but oxalic acid is cheap (5 lbs for $17 online or you can buy it at one of the big box hardware stores) and does a good job as well, just FYI.
