The T-Ester material allows several sterilization methods. You can use any of the methods such as boiling, steam sterilization, chemical sterilization and UV sterilization for T-Ester bottles.

When using UV sterilizer with drying function, it is necessary to place the bottle body at least 1 inch (2.54cm) away from the inner wall/ceiling where the air ventilation outlet is. This may avoid any damage or deterioration of the bottle.
