In grade school, they show how teeth are corroded by soda on eggs. As a matter of point, Coke (regular at the time, before new coke, old coke, classic coke, clear coke, etc) worked better than pepsi at corroding egg shells. Talk about fear factor.
Beyond that, anything with tons of Vitamen C and no sugar would in theory work better. Vitaman C is acidic. Works wonder on brass and shiny stuff. But coke would work better due to it's "fizz" lifting things out.
I would be hesitant to poor anything in a frame due to corrosion issues, unless you could be sure to clear it out. You can save money on free up lubricants by using coke, but you'll need some sort of preservative to prevent future problems. Sort of throwing the baby out with the bath water, in my humble, not to experienced opinion.
I'm a bit of a hack on many things, but I would say find a long metal rod of good thickness, and the apropriate sized BFG should solve the problem. Measure twice. Line up correctly, and there you go. No chemicals, no fuss.
