Use a damp cloth to keep your bottle clean and dirt free. When not in use, drain completely and store with stopper removed, in a cool, dry, dark place. We recommend hanging the bottle upside down with the stopper off so that the bottle becomes completely dry inside.The bottle should be kept away from direct exposure to sunlight. Sunlight can discolour the bottle and harm the rubber, ageing and degrading it. Do not place anything on top of the bottle during storage. Keep bottle fully extended. Keeping the bottle bent will create a crease in the rubber which will weaken it. Please be aware that in areas with harder water, the rubber can degrade more quickly, so it is important to check your bottle before each use.
Cold use: Continuous freezing and heating of the rubber, especially in hard water areas may reduce the lifespan of the natural bottle. For this reason, we recommend using one bottle for freezing and one for heating.
Warning: Do not fill using water from the domestic hot water system as this can considerably shorten the hot water bottle’s life. Prevent contact with hot surfaces, oil or grease. Do not heat in a microwave oven. This is not a toy; keep out of reach of children.
