No More Dullness and Odors! How to Care for Baby Bottles the Right Way
After giving birth, many new mothers are surprised to find that baby bottles can quickly become dull, change color, and sometimes develop stubborn odors even after being washed multiple times. Some mothers also wonder why, after sterilization, the bottle still looks cloudy despite not being overused. Concerns naturally arise. Is it still safe to use? Is it truly sterile? Does the color change mean the bottle is damaged?
This condition is actually very common, especially if the bottle is made from ordinary plastic that is not designed to withstand daily sterilization and intensive use. The good news is that there is a proper way to care for baby bottles so it stays clean, hygienic, and durable. The key lies not only in how you wash it, but also in the bottle material you choose.
Moms, Caring for Baby Bottles Cannot Be Done Carelessly
Baby bottles require special care because breast milk and formula both contain relatively high fat content. If not cleaned properly, fat residue can build up and cause odors or a white film that is difficult to remove. In addition, baby bottles are repeatedly exposed to heat from sterilization processes, especially if you use boiling water or steam sterilizers.
Bottles made from low quality plastic usually turn yellow quickly, soften, or even absorb lingering milk odors. This color change occurs because the plastic structure is not stable enough to withstand high heat and steam pressure. If bottles are not washed or stored properly, bacteria can grow in small areas such as silicone seals or grooves in the bottle cap.
For this reason, it is important for mothers to choose bottles designed for intensive use while also learning how to care for baby bottles correctly. Bottle material greatly affects both safety and durability.

PPSU is known as a medical grade material with high resistance to heat, pressure, and long term use. Hegen PPSU bottles come with several advantages that set them apart from regular plastic bottles.
1. Heat resistant up to 180°C
Hegen PPSU can withstand extreme temperatures without changing shape, softening, or turning yellow even with daily sterilization. This material is highly stable and does not easily degrade under repeated heat exposure.
2. Remains stable after repeated heating
As a medical grade material, PPSU stays strong even when exposed to steam sterilizers or boiling water. This is why Hegen bottles remain clear and are not easily damaged despite daily use.
3. Does not absorb odors and oils
Because it does not absorb fat from breast milk, Hegen PPSU bottles do not retain fishy smells or sour milk odors. The bottle stays clean and fresh even after long term use.
4. Clear and anti dull surface
Hegen PPSU bottles are resistant to scratches, making it easier for mothers to check the cleanliness of the interior. The consistently clear surface helps ensure that no stains or residue are left behind.
5. Hegen bottle system with minimal parts
Hegen is designed with fewer components, leaving fewer hard to clean gaps. This makes washing faster, more hygienic, and more efficient for busy mothers.
6. A Long Lasting and Eco Friendly Investment
PPSU bottles are designed to support a child’s growth over the long term without frequent replacement.

To ensure bottles remain hygienic and durable, here is a practical daily care guide.
1. Rinse immediately after use
Rinse the bottle as soon as your baby finishes feeding to prevent breast milk residue from drying and sticking.
2. Use baby safe bottle soap
Choose a mild and baby safe soap for washing bottles. Avoid harsh detergents that can damage silicone details or cause the bottle to become dull faster.
3. Use a soft bottle brush
Although Hegen PPSU is scratch resistant, it is still recommended to use a soft brush to protect small components such as the nipple or seal.
4. Pay attention to often overlooked parts
Make sure to clean silicone seals, grooves on the Hegen cap, and the bottom of the nipple where residue often accumulates.
5. Rinse with running water
Do not leave soap residue behind, as it can affect the aroma and taste of breast milk or formula.
How to Sterilize Baby Bottle Properly
Hegen PPSU bottles are safe for various sterilization methods. Mothers can choose the most practical option for daily use.
1. Steam sterilizer
This is the most common method and is ideal for PPSU because the material is stable under steam pressure.
2. Boiling in hot water
Hegen PPSU is safe to boil without the risk of melting or discoloration. This method is suitable for mothers who do not have an electric sterilizer.
3. UV sterilizer
This method is also safe for PPSU, but pay attention to sterilization duration since excessive UV exposure may affect the appearance of other plastic bottles stored together.
4. Do not mix with low quality bottles
During sterilization, low quality plastic bottles may release residue or odors that can transfer to other bottles. It is best to separate them for safety.
Thanks to the superior PPSU material, Hegen bottles remain durable and undamaged regardless of the sterilization method used.

After washing and sterilizing, proper storage plays a crucial role in maintaining bottle hygiene.
1. Air dry naturally
Place bottles on a clean drying rack and let them dry naturally. Avoid wiping with towels as this can transfer bacteria.

Do not seal bottles too tightly during storage to prevent moisture buildup that can lead to mold growth.
3. Use a dedicated bottle storage box
Hegen features a stackable design that makes storage neater and more hygienic. This helps keep bottles clean and protected from dust.
