Learn how to clean and maintain your Ceres Chill straw top and infuser to keep them in top condition. Get practical tips for long-lasting use.
Your Ceres Chill straw top and infuser are handy accessories that make feeding on the go easier. The straw top lets you sip milk directly from the chiller, while the infuser lets you add fruit for a hint of flavor. To keep them working well and lasting long, a little regular care goes a long way.

In this guide, we’ll walk you through simple cleaning steps, daily maintenance habits, and what to do if parts wear out. Whether you use the OG+ Portable Chiller/Warmer or the CeresBFF OG+ Chiller/Warmer, these tips apply to any Ceres Chill bottle with a straw top or infuser.
Why Proper Care Matters
Your Ceres Chill straw top and infuser come into direct contact with breastmilk and fruit, so keeping them clean is essential for hygiene and performance. Over time, milk residue can build up in the straw and the infuser’s mesh, leading to odors or clogging. Without regular care, the straw’s silicone can also become stiff or discolored, and the infuser’s mesh may tear.
By establishing a simple routine, you can extend the life of these parts and ensure they’re always ready for use. Plus, clean parts mean your milk stays fresh and free from any lingering tastes from previous uses.
- Prevents bacteria growth and keeps milk safe for your baby.
- Maintains smooth milk flow through the straw.
- Keeps the infuser mesh intact for effective fruit infusion.
Daily Cleaning Routine
After each use, disassemble the straw top and infuser. Rinse them under cool or lukewarm water to remove milk residue. Avoid hot water, as it can set protein stains. Use a mild dish soap and a soft brush or sponge to gently clean the straw’s interior and the infuser’s mesh. You can use a bottle brush or a straw cleaner to reach inside the straw.
For the infuser, open it and rinse the mesh thoroughly. If you used fruit, remove any leftover pieces and rinse well. Then, let all parts air dry completely on a clean drying rack. Ensure there’s no moisture left before reassembling to prevent mold or mildew.
- Use a dedicated straw brush for thorough cleaning.
- For stubborn residue, soak parts in a solution of warm water and baking soda for 15 minutes.
- Always air dry parts completely before storing.
Deep Cleaning and Sanitizing
Once a week, do a deeper clean. You can use a baby-safe sanitizing solution or boil the parts (check the manufacturer’s guidelines first). For the straw top, ensure the silicone straw is removed and washed separately. For the infuser, soak it in a vinegar solution (1 part vinegar to 3 parts water) to remove any mineral buildup or lingering odors.
After soaking, rinse thoroughly with clean water. Avoid using abrasive cleaners or scrubbers that could scratch the plastic or damage the mesh. Also, never put these parts in the dishwasher unless the manufacturer explicitly states they are dishwasher-safe, as high heat can warp them.
- Boil parts for 2-3 minutes for a deep sanitize (check heat resistance).
- Use a vinegar soak to remove odors and mineral deposits.
- Inspect the mesh for any tears or damage during cleaning.
Storing and Handling Tips
When not in use, store the straw top and infuser separately from the chiller to prevent any lingering smells. Keep them in a dry, ventilated area. Avoid leaving the straw top assembled for long periods, as this can cause the silicone to compress and lose its shape.
Handle the infuser gently, especially when inserting or removing it from the bottle. Pulling on the mesh can cause it to tear. Instead, hold the base and twist gently. If you’re using the infuser with fruit, choose soft fruits that won’t puncture the mesh, and avoid overfilling it.
- Store parts with lids off to allow air circulation.
- Replace the straw if it becomes cracked or loses its flexibility.
- Consider buying a replacement infuser if the mesh gets damaged.
When to Replace Parts
Even with the best care, straw tops and infusers will eventually wear out. The silicone straw may become stiff, discolored, or develop cracks, which can harbor bacteria. The infuser mesh might tear or become misshapen, affecting its ability to keep fruit contained.
If you notice any of these signs, it’s time to replace the part. Ceres Chill offers replacement parts like the Replacement Upper Parts/Collection Cup, which includes a new straw top. You can also purchase a new infuser separately. Regularly inspecting these parts during cleaning will help you catch wear early.
- Replace the straw every 2-3 months if used daily.
- Check the infuser mesh for holes or stretching.
- Keep spare parts on hand so you’re never without a clean set.
Caring for your Ceres Chill straw top and infuser is simple and keeps your feeding routine smooth and hygienic. By following these daily and weekly cleaning steps, storing parts properly, and knowing when to replace them, you’ll enjoy long-lasting use. For added convenience, consider having a backup set of parts so you’re always prepared.
