Frequently Asked Questions
How do I keep sand out of container seals at the beach?
Prevent sand intrusion by keeping lids closed until you’re ready to eat, placing containers on a towel or insulated mat instead of bare sand, and choosing screw-top jars or lids with continuous silicone gaskets. After use, rinse the silicone gasket and lid threads with fresh water to remove trapped sand before it grinds down the seal.
Are glass containers safe in the sun and on hot days?
Tempered borosilicate glass resists thermal stress better than standard glass and won’t warp in sun, but it will get hot to the touch and can break if dropped. Use a cooler or shade to protect both food temperature and container integrity; avoid putting hot liquids into non-heat-resistant glass jars.
What should I do if a silicone gasket starts leaking after a season of beach use?
First, clean the gasket and lid thoroughly—sand and oils are common causes of poor sealing. If leaks persist, replace the gasket if the brand offers spares; otherwise consider switching to a screw-top jar or a lid with a deeper silicone channel. Regular replacement of worn gaskets keeps containers reliably leakproof.
