Setup, Compatibility & Care
To ensure the longevity of your Sanger Hot Water Bottle, always use water that is hot but not boiling, as extreme heat can degrade the rubber over time. When filling, hold the bottle by the neck in an upright position and fill only to two-thirds capacity to allow for air expansion. Before sealing, gently squeeze the bottle until water appears at the neck to expel trapped air. For care, avoid contact with oils, greases, or direct sunlight, which can cause the rubber to perish. After use, empty the bottle completely and store it in a cool, dry place with the stopper removed to allow the inside to dry out fully.
