Using and caring for your 4Planet products is simple. We recommend rinsing them with hot water after each use, especially if they have been used to store liquids other than water.

Maintain your 4Planet products to ensure long-term use:

• Use warm water and a mild, neutral soap.
• Alternatively, try a mixture of warm water and vinegar, or a teaspoon of baking soda for a natural cleaning option.
• After washing, allow the bottle to air dry upside down without the lid.
• We strongly advise against putting your bottle in the freezer. The expansion of liquids as they freeze can deform your bottle, potentially damaging the welds that hold it together. Freezing any of our products will void the warranty against manufacturer defects.

Note: Small spots may appear inside your bottle over time, particularly with coffee or black tea. This is normal and does not affect the safety or durability of your 4Planet products.
