what i did was put in baking soda after my acid bath to neutralize it then i hose them down and soaked in RO water for 1 day with a hang on back filter with carbon. I then took it out and sundried the rocks for another 1-2 days then back in ro water it went then back out in sun then into a bin with saltwater and a pump and a lid for 3 months. Hope that helps scott.
