Direct answer: To clean your Nuby RapidCool, use a thorough rinse and cleaning routine that matches how you plan to sterilize afterward. Here are reliable methods observed in user guides and consumer videos:
- Hot-soapy wash (daily cleaning):
- Disassemble the RapidCool as much as possible (lid, seals, and any removable parts).
 - Wash all parts in hot water with mild dish soap, using a bottle brush to remove milk residue.
 - Rinse thoroughly with clean water to remove all soap.
 - Allow parts to air-dry completely before reassembling.
 
 - Cold-water sterilization (alternative method):
- After a clean wash, soak the parts in cold water with a Milton-style sterilizing solution (as directed on the sterilant’s label) for the recommended time.
 - Rinse briefly if the sterilant requires it, then air-dry before reuse.
 - This method is popular for quick turnaround without heat.
 
 - UV sterilization (if you have the RapidSterilise or equivalent):
- Place the cleaned RapidCool and lids in the UV sterilizer according to the device’s instructions.
 - Run the cycle (often about 1 minute) and allow components to dry or air out before reassembly.
 
 - Quick check before next use:
- Ensure all seals and the digital lid (if applicable) are clean and free of residue.
 - Reassemble fully and inspect for any signs of wear or buildup.
 
 
Tips and notes:
- Some caregivers prefer a “hot shot” style cleaning: dissolve a sterilizing tablet in a bottle of warm water, soak all parts, then rinse and air-dry. Follow the tablet’s instructions for concentration and soak time.
 - If using Milton or other liquid sterilizers, ensure you follow the product’s instructions for dilution and contact time, and rinse only if required by the product to avoid ingestion risk.
 - Regularly remove and clean the Rubber seal in the lid to prevent milk buildup.
 - If you use a UV sterilizer, confirm the device reaches the required sanitization level (e.g., 99.9% bacterial kill) and that it’s compatible with the RapidCool components.
 
If you’d like, specify which cleaning method you prefer (hot soap wash, Milton cold sterilization, or UV sterilization), and I’ll tailor a step-by-step checklist and timing for your exact RapidCool setup.
