FAQ Section

How often should I clean my stainless steel water bottle?

Can I leave water in my stainless steel bottle overnight?

Yes, you can leave water in your stainless steel bottle overnight. However, to ensure the water stays fresh and to maintain bottle hygiene, it's advisable to empty and rinse the bottle if the water has been sitting for more than 24 hours.

Why is there a metallic taste in my stainless steel water bottle?

A metallic taste can sometimes occur if the bottle is new, not cleaned properly, cheaply made, or left with water in it for too long. To eliminate this taste, use a vinegar rinse or baking soda soak as described above. If the taste persists, consider purchasing another stainless steel water bottle like the dual chamber Splitflask tumbler.

Is it safe to store hot beverages in my stainless steel bottle?

Most stainless steel bottles are designed to handle both hot and cold beverages safely but one at a time. Only the Splitflask dual chamber tumbler can handle hot and cold beverages at the same time - one in each chamber. However, check the manufacturer’s specifications to ensure your bottle is suitable for hot liquids, as sudden temperature changes can affect the bottle's integrity.

To cool your drink, put the bottle in the fridge prior to filling it or add ice cubes directly to the water.

Prevent mold by ensuring your bottle and its lid are completely dry before storing them. Regular cleaning and airing out the bottle also help prevent mold growth. If your bottle has a musty smell or visible mold, a vinegar soak overnight can help eliminate it.

Yes, using a reusable stainless steel water bottle significantly reduces reliance on single-use plastic bottles, making it an environmentally friendly choice. Stainless steel is also recyclable, adding to its eco-benefits. Also, if you would like to double your sustainability efforts, consider using a dual chamber tumbler like the Splitflask which will allow you to eliminate the use of two single use plastic beverage containers at a time.
