Quick Answer
Clean your FusionCap lid regularly by rinsing it after each use and doing a deeper soak every week to prevent mineral buildup and keep the CO2 release mechanism working smoothly.
Why Regular Cleaning Matters
The FusionCap lid controls how fast or slow CO2 is released into your drink. If residue or mineral deposits build up inside the valve, the carbonation control can become stiff or inconsistent. A quick rinse after each use prevents most issues, but a weekly deep clean removes stubborn buildup that plain water misses.
Skip harsh detergents or abrasive scrubbers—they can damage the silicone seals and plastic components. Stick to mild dish soap and a soft brush for the best results.
When to Replace vs. Clean
If the lid still feels sticky or leaks after a thorough cleaning, the silicone gasket may be worn. Replacement parts are available separately, but regular maintenance usually keeps the lid working for years. The FusionCap is compatible with the InFizz Fusion (BCA800), so keeping the lid clean ensures consistent performance with your carbonation system.
Step-by-Step Cleaning Guide
- Rinse Immediately After Use: Remove the lid from the bottle and rinse it under warm running water for 15–20 seconds. Pay extra attention to the valve area where CO2 enters. Don't let sugary or flavored drinks dry inside the lid—they harden and clog the valve.
- Disassemble the Lid (If Possible): Gently twist or pull apart any removable parts (like the silicone gasket or inner cap). Refer to your manual—not all versions disassemble the same way. Forcing a part that doesn't come off can crack the plastic. Only separate pieces designed to be removed.
- Soak in Warm Soapy Water: Fill a bowl with warm water and a few drops of mild dish soap. Submerge the lid parts for 10–15 minutes. Use a soft bottle brush to gently scrub the valve opening and threads. Avoid soaking the lid for longer than 30 minutes—prolonged exposure to soap can degrade the silicone seal.
- Rinse and Air-Dry Completely: Rinse all parts thoroughly under clean running water to remove any soap residue. Shake off excess water and place the parts on a clean towel to air-dry. Reassemble only when fully dry. Trapped moisture inside the valve can cause mold or mildew. Let everything dry at least 2–3 hours before reassembling.
