The Waterford Lismore pattern is a stunning combination of brilliance and clarity. Ice tinkles musically against fine crystal with the Lismore Tall Platinum Iced Beverage glass; a generously proportioned glass equally suitable for filling with water, juice or ice-cold cocktails. A lustrous platinum rim adds a touch of elegance to any occasion, while Lismore"s signature diamond and wedge cuts combine with the stunning clarity and comforting weight of Waterford"s hand-crafted fine crystal to make this a particularly beautiful example of classic drinkware. Combine quarter cup ammonia with a mild lemon detergent. Rinse in clean water and air dry on a rack. Clean vases and decanters by filling them half-full with moderately hot water, a small amount of mild detergent, two tablespoons of white vinegar or ammonia and 1/2 cup uncooked rice. Swirl the rice around for a few minutes to remove residue.
