A true investment piece is built to last for years, not months. Proper maintenance is simple yet crucial. Hand washing with mild soap is generally recommended to preserve the vacuum seal’s integrity and the exterior finish, as dishwasher detergents can be harsh on seals and coatings. For stubborn coffee or tea stains, a soak with a baking soda solution works wonders. Regularly inspect and clean the silicone sealing ring to maintain its leak-proof quality. A product backed by a substantial warranty often reflects the manufacturer’s confidence in its materials and craftsmanship, offering peace of mind.
