Frequently Asked Questions
How can I tell if a bottle is leaking or just sweating?
Condensation (sweating) forms when a cold bottle transfers temperature to the outside, leaving droplets but no wet spots inside the cap or seam. A true leak usually leaves damp inside caps, threads or gaskets. To test, close the bottle, tip it upside down over a paper towel and wait a minute — a towel that stays dry indicates sweating or a sealed design; visible droplets indicate a leak that needs the gasket or cap checked.
Do straw lids increase the risk of leaks?
Straw lids are convenient but have more small parts and seals that can crack or wear, which increases leak risk over time. If you choose a straw lid, prefer models with replaceable straw components and check seals regularly. For maximum leak safety in mixed bags, a solid screw-top or engineered Flex Cap is usually safer.
How do I maintain seals to prevent leaks?
Rinse and dry lids after use, remove and clean gaskets periodically with a brush to clear debris, and inspect rubber seals for cracks. Replace worn gaskets or brittle plastic parts immediately — many brands sell replacement parts. Avoid dishwashers for small gasket pieces unless the manufacturer says it’s safe, as high heat can warp seals.
