O.K.,checked out Hugh’s blog, and have seen many rust removal techniques, but my personal favorite is good old fashioned naval jelly, simply brush it on, (a small paint brush may work for allen heads but I typically use a toothbrush), let it sit for a few minutes, and rinse off with water and, Viola!, rust is gone! It may take more than one application, depending on how rusty the part is, but one or two has worked for most parts I’ve done. You will still have to polish when you’re done, but without having to get through the rust first. Much faster than polish alone. All that being said, FOLLOW THE DIRECTIONS ON THE BOTTLE!!!!! This stuff is phosphoric acid in a liquid/jelly form, “metal/steel/iron only” it says on the label, not for use on chrome or aluminum, although I have used it on both with awesome results, just don’t let it sit on there near as long, you can always re-apply if need be. I love this stuff!! Brush it on, rinse it off, no rubbing, grinding, sanding, scratching, well, you get the idea . . . it’s not very labor intensive. Find it at your local hardware store, or maybe Menards, Lowes doesn’t carry it. Good Luck!!
