How do I clean my Stash bottle?

We recommend rinsing out your Stash bottle thouroughly before your first use and cleaning it regularly. Due to the Stash's flexible design, we do not recommend placing it in the dishwasher. Method One - Fill your bottle with warm water and use a bottle brush along with mild soap to scrub it clean. Rinse well and set upside down to dry. Method Two - Fill your bottle with warm water and drop in one Bottle Bright tablet, let sit for up to fifteen minutes. Rinse and set upside down to dry.

my favorite bottle

LOVE this bottle! I have both sizes of the Stash - the 750ml is helpful for when I’m traveling, and taking it on airplanes and when commuting to work every day. I prefer the 1L for hiking and backpacking. It dries out really easily after I clean it, which is helpful. After using it with electrolyte mix in it, my bottle did need some extra cleaning (I like to use Bottle Bright when it gets really dirty). However, other than that, it’s handy and light and durable, which makes this my favorite bottle to use.
