Use & Care
Are MiiR bottles dishwasher safe?
  Yes. However, we recommend hand washing any of our colored bottles. With the exception of the natural stainless steel, our bottles feature a water-based paint followed by a clear protective coating, which can deteriorate when regularly exposed to high water temperatures. For best results, bathe your bottle with a long-handled bristle brush, soap and warm water.
Can MiiR bottles be put in the freezer?
  No. When liquids expand into a solid, a force is created that can damage the micro-welds that keep the bottle intact. Freezing your MiiR will put your bottle’s warranty on ice.
Can my MiiR hold hot tea or my daily coffee?
  MiiR insulated bottles are perfect for your daily hot tea or coffee. The vacuum sealed double wall design will keep your hot beverages hot for up to 8 hours without burning your mitts, and will also keep your cold beverages cold for up to 24 hours without perspiring.

Though our classic bottles are tough, they are not insulated and therefore shouldn't be treated like your typical mug. Your MiiR can perspire with chilled beverages, but our classic bottles are not designed for hot beverages, so please don't try it.
What about alcohol? Can I carry that too?
  Are you 21? Then what's stopping you? After using, we recommend immediately scrubbing your bottle's interior with a long-handled bristle brush, a bit of liquid dish soap and warm water, rather than tossing it in the dishwasher.
What if I want OJ, another juice variety or a smoothie to-go?
  You certainly can! 18/8 means durability and dependability, and we guarantee it. Acidic drinks will not affect nor deteriorate our stainless steel. For smoothies or other iced beverages we recommend using the MiiR insulated bottle to make sure you don't get the condensation build up on the outside of the bottle. Just remember – After using we recommend immediately scrubbing your bottle's interior with a long-handled bristle brush, a bit of liquid dish soap and warm water, rather than tossing it in the dishwasher.
