Well, you have three choices, you can use Oxalic acid or Muriatic acid (Muriatic acid is another name for hydrochloric acid) They are not delimers, although they might work for that use. Muriatic acid is used to etch concrete after all, so I'm sure it attacks lime. Or you can use Marykate. The three main ingredients in it are Muriatic acid, Oxalic acid and Phosphoric acid. Again, I cannot promise you that they will remove the adhesive residue, but I can speak from experience and tell you that it it has never failed to remove everything from my boats hull. rust stains, oil stains, scum, marine growth, creosote rub marks, you name it, it's removed it and it does it in a hurry. And of course you can also try Goo Gone (available in just about any home center store). or (no, I'm not making this up) Peanut butter. My wife uses it all the time to remove the sticky goo left on an item after she removes a sticker or label from something she's bought.... and damn if it doesn't work.
