How to Clean Dr. Brown's Bottles and Vent Parts
Dr. Brown's Options+ bottles need more than a quick bottle-brush pass because milk can remain inside the long vent reservoir and the small openings in the vent insert. The manufacturer supplies a narrow cleaning brush specifically for those passages. A complete wash therefore means disassembling the bottle into its individual parts, flushing the internal vent system, gently cleaning the nipple and allowing every piece to dry before reassembly. This guide covers common genuine Dr. Brown's narrow and wide-neck Options+ bottle systems. Bottle materials, sterilizing limits and dishwasher placement can vary, so check the markings and instructions for the exact bottle and accessory rather than treating every Dr. Brown's product identically.

Step-by-step instructions
Step 1: Wash hands and disassemble every part
Remove the cap, nipple, collar, vent insert, long reservoir tube and bottle. Separate pieces that appear loosely connected instead of washing the assembled vent. Milk film can hide where the insert meets the reservoir and beneath the nipple flange. Place small silicone pieces in the clean basin so they cannot fall into a sink drain or contact a contaminated sink surface.
Step 2: Rinse away fresh milk promptly
Rinse each milk-contact surface with clean water soon after feeding. Run water through the reservoir tube and both vent openings rather than rinsing only its exterior. Prompt rinsing keeps protein and fat from drying into narrow passages, but it does not replace washing with detergent. Discard unfinished formula or milk according to feeding-safety guidance before beginning.
Step 3: Wash the bottle and broad rigid parts
Fill a dedicated basin with warm water and mild dishwashing liquid. Use a non-scratch bottle brush on the bottle interior, threads, collar, cap and open surfaces of the insert. Work the brush around ledges where cloudy residue collects. Avoid abrasive pads that can roughen plastic and make future residue harder to see or remove.
Step 4: Clean the internal vent system
Use the supplied narrow brush for the small holes in the vent insert and the full length of the reservoir tube. Enter each passage gently; do not widen an opening or substitute a sharp pin. Flush with soapy water until no film remains, then hold the pieces toward a light to check the tube and junctions. Replace a brush whose bristles are bent, dirty or unable to reach effectively.
Step 5: Wash the nipple without damaging it
Turn the nipple as directed so the flange and underside can be washed, then massage it in the soapy water. Use only a soft appropriate brush on accessible surfaces. Never enlarge the feeding hole with a tool, and inspect the nipple for tears, tackiness, swelling or thinning. A damaged nipple is replaced rather than scrubbed aggressively or repaired.
Step 6: Rinse and air-dry completely
Rinse all pieces under clean running water, including water through both vent passages. Place them separately on a clean drying rack with openings positioned to drain. Do not towel-dry inside the bottle or reservoir, because a used towel can add lint and microorganisms. Reassemble only when the narrow tube, silicone parts and bottle are fully dry.
Step 7: Use the dishwasher or sterilize only as approved
Dr. Brown's identifies compatible bottle parts as top-rack dishwasher safe; contain nipples and vent pieces in a closed basket and clean vent passages before loading when residue is visible. For first use, the manufacturer directs boiling the nipple for five minutes. Later sanitizing needs depend on the exact parts and household guidance, so follow current Dr. Brown's instructions and keep every piece away from an exposed heating element.
Step 8: Inspect and reassemble the Options+ system
Fit the reservoir to the vent insert without gaps, seat the assembly in the bottle and install the nipple and collar without cross-threading. Check that all air passages are clear and that no cleaning liquid remains. Options+ bottles may be used with or without the internal vent at the appropriate stage, but follow the manufacturer's assembly directions; do not mix unmatched Natural Flow, narrow and wide-neck pieces merely because they seem to fit.
