Don’t Buy Just Any Bottle Brush! Choosing the Wrong Material or Using It Incorrectly Makes Bottles Dirtier

Many parents think "any bottle brush that can scrub is fine," but in reality, choosing the wrong one not only leads to incomplete cleaning but may also damage the bottle and leave behind bacteria.

• If you have silicone baby bottles or silicone nipples at home, never use a hard-bristled nylon brush. The hard bristles can scratch the silicone surface, creating tiny scratches that easily trap milk residue and bacteria—these will be ingested by the baby during the next feeding. It’s recommended to choose a silicone bottle brush: soft and elastic, it can clean thoroughly without scratching the silicone.
• For glass bottles, a hard-bristled nylon brush can be used, but pay attention to cleaning hard-to-reach areas—the curved bottom of the bottle, the nipple’s suction holes, and the threaded neck of the bottle all need to be scrubbed carefully to avoid leftover milk residue.
