Hello I have at last received a supply of oxalic acid and am in the process of treating the wheels sorry to the authors who suggested steel or copper wool there is no comparison and so much easier to soak in solution of oxalic acid to get rid of rust. Have also taken to soaking small parts in laundry bag such as cotter pins cannot believe that the pins are still usable as it only took a small tap with a hammer to remove the pins without damageing the threads on the pins.It is a slow job removing the old crap and gunge from the metal parts and it is still heads or tails for a sandblasting and powdercoating job on the frame,forks, mudguards, etc.for 45 pounds or a rattle can spray what do you think. I have read a few threads on do it yourself but the jury is still out!!!!!!
