Bkr bottle: Wash before use. Your bkr bottle glass, sleeve, straw, and cap are dishwasher safe* on the top rack. Removing the sleeve is optional but easy. See our Instagram bkr care highlight for a founder tutorial. If you're cleaning by hand, we recommend using hot soapy water and our perfect bottle brush. If you'd like to speed up the drying process, roll up a piece of paper towel so it's thin enough to get in the opening of the bottle, but wide enough to stay put.  Put the roll 3/4 the way down the bottle (with the top of the roll out the top of the bottle, like a wick) and leave it overnight.   We recommend storing your bkr with the cap off.   *Please note, if you have the Swarovski Crystal cap, please wash by hand only and DON’T soak as it is not dishwasher safe. Bkr cup: Wash before use. Your bkr Cup glass, sleeve, straw, and cap are dishwasher safe on the top rack – the buttons and gasket can go in the dishwasher basket. We recommend rinsing immediately after use before placing in the dishwasher to avoid stains. Treat your bkr cup like a fancy wine glass (gently) and your gasket and straws like your teeth (clean them or they could stain) Wash all pieces of the cap separately. To remove gasket pull down from the flat area above the K in the bkr logo on the underside of the cap. Removing the sleeve is optional but easy. See our Instagram bkr care highlight for a founder tutorial. If you're cleaning by hand, we recommend using hot soapy water and our perfect bottle brush.  We recommend storing your bkr with the cap off. Bkr straws: Dishwasher safe top rack. To remove stubborn smells or tastes from straws, bake at 250 degrees for 30 minutes, smell carefully, bake for another 10 minutes if smell persists.
