Quick answer
Boil glass bottles for 5 minutes, use a steam sterilizer, or soak in cold water sterilizing solution. Always start with cool water and avoid sudden temperature changes to prevent cracking.
Why glass bottles need special care during sterilization
Glass is durable and reusable, but it can crack from thermal shock—a sudden temperature change. For example, placing a hot glass bottle under cold running water or into a cold sterilizing solution can cause it to shatter. Always let the bottle cool down gradually after boiling or steaming.
Another common mistake is stacking bottles too tightly in a boiling pot or steam sterilizer. Glass expands slightly when heated, and if bottles press against each other or the pot wall, they can develop stress fractures. Leave space between each bottle and the pot sides.
Step-by-step sterilization guide
- Boiling method: Place disassembled bottles and nipples in a large pot. Cover with cool tap water—do not use hot water. Bring to a rolling boil, then boil for 5 minutes (no longer). Use tongs to remove items and place them on a clean towel to air-dry. Never add glass bottles to water that is already boiling. Start with cool water to avoid thermal shock.
- Steam sterilizer method: Follow your steam sterilizer's instructions. Typically, place bottles upside down in the sterilizer, add the recommended amount of water, and run the cycle. Let the bottles cool inside the sterilizer with the lid closed for at least 10 minutes after the cycle ends. Do not open the lid immediately—the rush of cool air can cause glass to crack. Allow gradual cooling.
- Cold water sterilizing solution method: Fill a clean container with cool tap water and add the sterilizing tablet or liquid as directed. Fully submerge disassembled bottles and nipples, ensuring no air pockets remain. Soak for the time specified on the product label (usually 30 minutes). Rinse with cooled boiled water before use. Use only cool water. Warm or hot water can react with some sterilizing chemicals and may also stress the glass.
