Frequently Asked Questions
Are insulated tumblers safe to use at the pool?
Yes — stainless steel insulated tumblers are safe and ideal for pool use. Choose a model with a secure lid to avoid spills and a No Sweat or DuraCoat finish to prevent condensation on furniture. Always rinse after use and dry parts like lids and straws to avoid trapped moisture.
Which lid type is best to avoid spills at the pool?
For the fewest spills, choose a truly leakproof lid or a leakproof straw system. BruMate’s U‑Turn straw tumbler is designed to be 100% leakproof even with carbonated drinks; other brands use rotating or sealed lids that reduce splashes but may not be fully leakproof.
How do I keep my tumbler from rusting or peeling?
Pick a tumbler with 18/8 stainless steel and a durable finish like DuraCoat, rinse it after saltwater or pool chlorine exposure, avoid abrasive cleaners, and follow manufacturer care instructions. If a lid or straw component is damaged, replace that part rather than the whole tumbler to prolong life.
