I use regular vinegar to test rocks. A few drops on the piece and if there's a reaction, don't put it into the tank. As far a cleaning, I rinse it well with the pressure nozzle attached to the garden hose, then leave it out in the sun for a few hours. Any bacteria would be killed with the combination of heat and sunlight. Then into the tank.
