Muriatic acid is strong enough to do a lot of damage to your eyes and mucous membranes as well as your skin. Goggles and gloves for sure. Muriatic acid seems a reasonable approach provided you use appropriate safety equipment. I would soak in RODI water first so that the acid isn't soaked up as much. I wouldn't dip it for longer than a couple hours as there is no point in getting the acid all the way to the middle of the rock since you are really only wanting to kill the surface nuisances. This method will essentially strip the outer layer of rock off. You will still need to leech the phosphate and nitrate from the rock by "cooking".
Freshwater is fine through the whole leeching process right up to the point you want to re-seed the rock with some live rock.
