had an old rusty inside cb550 tank decades ago.... looking around the house and garage for a suitable internal scraper to remove the oxidation, i happened to spy an old jar of pennies (yup, good ol' us 1 cent pieces).... what the hell, i figured.... guess it was about 10 bucks worth... dumped them inside, latched my cap on, and commenced shaking the tank for an hour or so.... after my arms gave out, i popped my cap, and dumped the pennies onto a few sheets of newspaper spread on the garage floor.... a pile of pennies, and lots of super-fine rust.... peeked into the filler, and lo and behold, clean bare steel.... dumped the pennies in a colander and shook them over the paper to filter out the major rust, then gave them a real good rinse... absolutely free, the pennies are softer than steel, so no scratching, and you can reuse them forever..... told that to a local cat about a year ago who was looking for something to get the rust out of a vulcan tank, worked for him too.... love the drier idea, though...lol sand in your fuel tank? major no-no.... paint the interior? major no-no... even if the paint doesnt dissolve, it can still leach... not so sure id like paint binders going through ding-wee carb jets.... or going into the combustion chamber....
