With proper antibiotics navel jelly can be cured. You can probably find NAVAL JELLY at WAL Mart also. You may also be able to find Phosphoric acid in a liquid form easier than the Naval Jelly. I think the Naval Jelly might be a little safer to work with than Muriatic acid , which can be found at building supply outlets, Muriatic acid is used for cleaning brick work, and etching concrete.
