Stoned Marble products are made to last a lifetime. Keep in mind that marble is beautiful and strong but also fragile. Rinse the marble products from Stoned with a mild detergent, not in the dishwasher. Water and other liquids that remain on the marble for a longer period of time could absorb and leave traces. Be careful with acids, such as lemon juice and vinegar, but also with products that strongly color such as beetroot and turmeric.
