How do I clean old family stones that are dirty or weathered?
Its best to start with a stiff nylon bristle brush and soap/water. If this doesn’t solve the problem we recommend going to bleach/water (about 50/50 solution of water to bleach – DO NOT USE BLEACH ON BLACK STONES). Always be sure to rinse immediately and never let the bleach dry on the stone. Another alternative is a pressure washer – just be careful not have the pressure setting too high. IN ALL CASES – be sure and test in an inconspicuous spot first to make sure it isn’t doing any damage.
