Lead crystal glass is softer than normal glass and has a far superior clarity. Please keep it out of contact with other items to avoid marking or scratching. Wash each piece individually by hand in warm water with a small amount of detergent. Rinse clean and then dry with a soft cloth. Do not use a dishwasher for cleaning since excessive heat and harsh detergents will cloud the surface and may possibly crack the crystal.
