If you’re like me, you love your stainless steel water bottle — it keeps water cold lots longer than any other type we’ve tried. Plus it’s significantly more durable — throw it in the bottom of the dinghy or the racing sailboat’s side tank and it’s easily accessible. Ours are from Thermos and insulated which works great in the hot tropical sun.
Plastic water bottles can leave an unpleasant flavor to water, and worse, there’s still a controversy about whether BPA used in many plastic water bottles is a toxic substance. Since we reuse water bottles aboard, we’re finding it easier to use the stainless water bottles than nalgene or other BPA free plastic bottles. But after a few uses, despite washing as best I can, the stainless bottle begins to smell less than fresh and even a bit moldy around the top. YUCK!
We found that using a common cleaning product already aboard can eliminate the problem, but you may want to invest in a bottle brush if you’re going to switch to stainless water bottles. To keep our bottles clean and fresh smelling, every few uses (not every time), we do the following:
1. Take off the cap and pour a splash of regular white vinegar into the bottle – a splash is probably 2 capfuls – enough to coat the entire interior surface. Then put the cap on and shake the bottle, splashing the entire interior with vinegar.
