"Hand-wash only" refers to items that should not be cleaned in a dishwasher. This label is often found on delicate materials, such as certain types of glassware, fine china, or specific fabrics. Washing these items by hand helps prevent damage, warping, or fading that can occur in high heat or with strong detergents used in dishwashers. To properly hand-wash, use warm water and a mild detergent. Gently scrub the item with a soft sponge or cloth, then rinse thoroughly. Allow it to air dry or dry it carefully with a soft towel. Following these steps helps maintain the quality of delicate items.
