How do you shine rocks after tumbling?

Then add some Borax (link to Amazon) or Ivory bar soap instead of grit or polish. Use about 1 tablespoon if you have a 3-pound tumbling barrel. You only need to run the tumbler for a couple of hours to achieve the desired effect. The Borax will thoroughly clean and polish the rocks to a high mirror shine!
