How to Clean Drusy Quartz

Clean the tiny crystals on the surface of the drusy quartz with unscented dishwashing detergent, water and a soft brush. If stains or coating are found on another part of the quartz, then use the steps below to clean the other parts of the stone.

Use a spot-cleaning gun, which cleans with a high-pressure water spray, to clean the surface of the quartz. If the surface of the quartz still isn't clean, use a tougher mechanical cleaning technique listed in steps 3 and 4.

Use an air abrasive tool, which blasts a stream of high pressure air with abrasive materials that act as a scouring powder. For quartz, tiny glass beads are best as the abrasive material because they are softer than the quartz. Do not use crushed glass, garnet sand or quartz sand, because they will damage your quartz. Use 80 pounds of pressure to start.

Use an air scribe, which is a small, hand-held jackhammer that uses air pressure to clean. An air scribe is the size of a marker or thick pencil.

Remove iron stains from your quartz with chemicals, if you do not have access to mechanical cleaning tools. Iron stains are caused by the minerals hematite and goethite and can be removed by soaking in a solution of sodium dithionate, oxalic acid, or hydrochloric acid.
