Boiling Method: Prepare a dedicated pot for boiling. Fill the pot with enough water to completely submerge the baby bottles (avoid overfilling, however; otherwise, the boiling water may cause the bottles to float up and tip over the rim of the pot, potentially damaging them). Ensure that the bottles themselves are filled with water to prevent them from floating to the surface. Bring the water to a boil; after it has been boiling for 5 minutes, add the nipples, caps, and other accessories. Cover the pot and continue boiling for another 5–10 minutes. Be careful not to boil them for too long, as this can easily cause the bottles to deform.
Steam Method: After thoroughly washing the baby bottles, place them in a specialized steam sterilizer and operate the device according to the instructions provided in the user manual. If you do not own a dedicated steam sterilizer, you may instead place the washed bottles in a steamer basket and steam them for 5–10 minutes using a standard stovetop setup. 3. Microwave Sterilization: Baby bottles can be sterilized by heating them inside a microwave-specific sterilizing container. Simply follow the operating instructions provided with the container. Note: Plastic baby bottles should not be placed directly into a microwave for sterilization; instead, they must be placed inside a container filled with water before being heated. Always read the detailed instructions on the baby bottle's packaging carefully before attempting any sterilization method.
