Why
Silicone nipples are generally more heat-resistant than latex, but both can degrade over time with repeated dishwasher use due to high heat and harsh detergents. Many brands explicitly state that nipples are dishwasher safe only on the top rack and with a gentle cycle, while others recommend hand washing to extend lifespan.
How do you wash baby bottle nipples?
If using a dishwasher, place nipples on the top rack away from heating elements and use a gentle cycle. For best longevity, hand wash with mild soap and warm water, then air dry.
What happens if you put baby bottle nipples in the dishwasher?
If you put a baby bottle nipple in the dishwasher, after one wash you may notice the silicone or latex becomes slightly tacky or cloudy. After repeated washes, the material will degrade more noticeably: silicone may become sticky, brittle, or develop small cracks, while latex can swell, lose elasticity, and tear easily. The damage is both cosmetic and functional — a degraded nipple can harbor bacteria in cracks, and a torn nipple poses a choking hazard or may leak milk. The nipple's lifespan is significantly shortened, and it may need to be replaced after just a few dishwasher cycles. Hand washing is strongly recommended to maintain safety and durability.
