Frequently Asked Questions
Are insulated stainless bottles safe to use around saltwater?
Yes—stainless steel (18/8 or 304) bottles are safe around saltwater if you rinse them with fresh water after exposure and dry them thoroughly. Finishes like powder coat, ceramicized paint, or anodizing add extra protection against pitting from salt. Replace worn seals and check lids for corrosion periodically.
Which lid type is best for boating to avoid leaks?
For the most secure seal on a boat, a full screw‑top with a robust O‑ring is the safest option. Locking straw caps and flip spouts are convenient but can be more prone to leaks — test them in a controlled setting before trusting them on rough water and make sure they have a positive lock.
How do I maintain bottles after a day at the beach to prevent rust or wear?
Rinse all parts (bottle, lid, straws, seals) with fresh water to remove salt, soap and warm water if needed, then air dry fully before storage. Periodically inspect and replace silicone O‑rings or straw seals. Avoid leaving salty moisture trapped inside or in crevices for long periods.
