use no chemicals at all! Then with a soft brush to get rid of dust then hold it under running water and either dry the air or gently pat them dry with a soft cloth. I would also clean through incense smoke and let it sit in a patch of moonlight to load. And yes, each crystal is placed on your altar:) Look into the properties of your crystal to see what specific forms of energy will give your work.
