Keep your baby's cup fresh and mold-free with these simple cleaning steps. Learn how to properly clean a silicone straw cup and prevent buildup.

Quick answer

To keep a silicone straw cup like the Squeeze & Sip clean and mold-free, disassemble all parts after each use, wash with warm soapy water and a bottle brush, then air dry completely before reassembling. Pay extra attention to the straw and valve where moisture hides.

Why regular cleaning matters

Silicone straw cups are popular for their soft, flexible straws that are gentle on baby's gums, but those same features can trap milk residue and moisture. Without thorough cleaning, mold and bacteria can grow in the straw or valve, leading to unpleasant odors or even illness. A consistent cleaning routine is the best way to keep the cup safe for daily use.

Step-by-step cleaning guide

Disassemble completely: Separate the cup body, silicone straw, valve, and lid. Most molds hide in the tiny crevices where parts connect. Common mistake: leaving the straw attached while rinsing — this traps milk inside.
Wash with warm soapy water: Use a mild dish soap and a bottle brush or straw cleaner to scrub the inside of the straw and valve. Rinse thoroughly under running water. Checkpoint: if you see any cloudy film, scrub again until clear.
Sanitize weekly: Boil the silicone parts for 5 minutes or use a steam sterilizer. This kills any lingering bacteria that soap alone may miss. Do not boil the cup body if it contains plastic — check the manufacturer's instructions first.
Air dry fully before reassembling: Place all parts on a clean drying rack with openings facing down. Let them dry for at least a few hours or overnight. Common mistake: reassembling while damp, which encourages mold growth inside the straw.
