GROWNSY Electric Bottle Sterilizer and Dryer Device

A: Hi there! Our sterilizer is designed to fit most standard baby bottles, including narrow-neck and wide-neck bottles (compatible with Dr. Brown's wide-neck bottles and Comotomo). The chamber holds up to 5 bottles at a time, plus pump parts, pacifiers, and accessories. If you're using an unusually tall or large bottle, feel free to measure the height and diameter — we're happy to confirm if it will fit!

A: Hi Lena! Yes, we recommend washing bottles first to remove any milk residue before placing them in the sterilizer. The unit uses high-temperature steam to clean, not to wash off milk or food residue — so a quick rinse or wash first helps the steam work more effectively. If you're looking to skip the hand-washing step altogether, check out our GROWNSY Bottle Washer — it automatically washes, rinses, and dries bottles and pump parts in one cycle, so you can go straight from the sink to the sterilizer (or skip it entirely). It's a time-saver for busy parents! Hope that helps!

A: Hi Sav! Yes, you can clean breast pump parts in this sterilizer. Most breast pump components — flanges, valves, membranes, bottles, and other small accessories — fit well in the chamber and can be safely steam cleaned. Just make sure to only place the parts that are safe for high-temperature steam (typically the plastic and silicone milk-contact parts). The motor unit, battery compartment, and any electrical components should not be placed inside. Always check your pump manufacturer's instructions to confirm which parts are steam-safe.
