 Q & A

Q. Are the silicone bottles safe with washing brush?

A. You can certainly use your bottle brush to clean our bottles. However, we think that bottle brushes aren’t too hygienic since they cannot be sterilized. Since our bottles have a super wide opening and has minimal parts, we highly recommend simply hand cleaning them. Just one less thing to worry about!


Q. Help! The nipple keeps collapsing!

A. Over time, milk residues can get trapped in the vent and prevent it from working properly. The best thing to do is to make sure that the ends of the vents (back of the nipple) are clear and free from any blockage. You can easily clean them with your fingers in warm water. Also, you can sterilize the nipple in boiling water for about 5 full minutes to clear out anything that may be clogged in the vent. But if this doesn’t fix the issue, please contact us and we’ll be more than happy to help you! (See the instruction down below for more detials.)


Q. Can I purchase parts (e.g. bottle rings, caps)?

A. For the time being, we do not sell parts separately. However, if you are in desperate need, please contact us at ask@comotomo.com.


Q. My bottle changed color, how do I remove this?

A. Over time, it is possible for silicone to slightly change in color. However, please be assured that this is purely cosmetic and that they are perfectly safe to use. To prevent discoloration, we recommend that the bottles are well washed after each use and frequently sterilized (at least once a week in boiling water for 5 minutes).


Q. Are the silicone bottles safe in boiling water?

A. Yes. Silicone is highly heat resistant. Our bottles are safe in temperature up to 248F. We recommend sterilizing our bottle in boiling water for approximately 5 minutes. To be safe, please avoid direct contact of our bottles with the boiling pot.


Q. My bottle has a slight odor, how do I get rid of it?

A. Like most containers, our bottles can retain some odor after extended use. Here is a tip from a savvy mom: Sterilize Comotomo bottles in boiling water for 5 minutes with a tiny bit of baking soda. Afterwards, air-dry the bottles (open side up) in a well ventilated area. This should help get rid of any smell in the bottle. Hope this helps!
