Instructions

  1. Buy Tools to Clean Your Minerals

    • 1

      Know where to go. Take the list in the "Things You'll Need" section and go to a hardware store if you'd like to see the tools in person. Otherwise, buy them online or through a catalog.

    • 2

      Consider the different minerals in your collection. You may need to buy several sizes of the same tool in order to properly clean them.

    • 3

      Look around the house before making a purchase. You may have some of the tools at home.

    • 4

      Take a trip to the craft store. You'll need several brushes of various textures and sizes to clean the minerals.

    • 5

      Consider buying plastic or acid-free containers for your minerals to be stored or displayed in.

    • 6

      Protect yourself. Wear gloves and an eye mask to prevent cleaning solution, debris and bacteria from coming into contact with your skin.

    Clean Your Minerals

    • 7

      Hold the mineral in your hand. Avoid using a vice, which can cause damage to the specimen.

    • 8

      Use an awl and scrapers to remove loose debris. Minerals can become quite dirty and caked with debris when found in a natural setting.

    • 9

      Continue to remove debris using tweezers. Because of their small size, tweezers are able to reach and grip smaller pieces of waste.

    • 10

      Proceed to using brushes with water or alcohol once all debris is removed. By checking the mineral's composition in a field guide, you can determine if water is best versus alcohol.

    • 11

      Use a sturdy brush and distilled water to clean topaz, quartz, garnet, beryl, tourmaline and spodumene.

    • 12

      Use a soft sable brush and distilled water to clean fragile minerals. Calcite should always be cleaned this way.

    • 13

      Pour alcohol over gypsum and borates like borax. This cleaning agent is ideal for both minerals.
