If your quartz crystals are encrusted with calcite, barite, or lime carbonates, you can try cleaning them with ordinary household vinegar and washing ammonia. You'll want to soak them for 8-12 hours in full-strength vinegar. Wash the crystals well, and then soak them for the same amount of time in washing ammonia.
Calcite (KAL-site) is the most common mineral found in Texas geodes, and its usual crystal formation is called the dogtooth spar. Most calcite is white, but impurities may tint it other colors. Much of it is fluorescent, and it may appear pink or red under ultraviolet light.
