Since heat may affect the bottle, it’s best to wash it with soap and water by hand.

Whether you are training for a marathon or need help keeping track of your water intake throughout your day, a time marker water bottle can be a helpful tool to ensure that you're staying hydrated. Before buying a time marker water bottle, consider the type of bottle you need. Time marker water bottles come in sizes, from small 12-ounce bottles to large 64-ounce ones. The size you'll need depends on how much water you plan to drink each day. If you're only looking to drink eight ounces of water per hour, for example, then a 12-ounce bottle will be plenty. However, if you're training for an endurance event and need to drink 64 ounces of water per hour, you'll need a larger bottle. Time marker water bottles come with various features, from simple designs that only have markings for hours to more complex designs that also include markings for minutes and seconds. Some bottles also include additional features like compartments for holding pills or other small items or filters that remove impurities from your water. Decide which features are most important to you before making your purchase. Finally, consider your budget. Time marker water bottles range in price from $10 to $50 or more, depending on the size and features of the bottle. If you're only looking for a basic bottle with hour markings, you can find something reasonably priced. However, if you want a large bottle with all the bells and whistles, be prepared to spend a bit more money
