Coke is surprisingly acid I recently measured the pH at 2.2 (presumably from a 
combination of carbonic and phosphoric acids).
But if you want something to remove carbonate scale, I suggest you check out 
no-frills white vinegar. It has about the same pH but no sugar. I'm not sure 
how it compares price-wise.
It's also good for removing scale from steam irons.
