Use & Care
Are MiiR hydration products dishwasher safe?
 

Yes. However, we recommend hand washing any of our colored products. With the exception of the natural stainless steel, our bottles, tumblers, and growlers feature either a water-based paint followed by a clear protective coating, or a powder coating, which can deteriorate when regularly exposed to high water temperatures. For best results, bathe your bottle, tumbler, or growler with a long-handled bristle brush, soap and warm water.

Can my MiiR go 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 and tumblers are perfect for your daily hot tea or coffee. The vacuum-sealed double wall design on our insulated bottle and travel tumbler lines will keep your hot beverages hot for up to 8 hours without burning your mitts, and cold beverages cold for up to 24 hours without perspiring. MiiR 12oz to-go tumblers also feature double wall insulation keeping hot beverages hot up to 4 hours, and cold beverages cold up to 8 hours.

Though our classic and slate bottles are tough, they are not insulated and therefore shouldn't be treated like your typical mug. Single wall bottles can perspire with chilled beverages, and are not at all designed to hold hot beverages - so please don't try it.

What about alcohol? Can I carry that too?
 

Are you 21? Then what's stopping you? And may we recommend to you our 64oz Growler – your perfect insulated vessel for urban brewery adventures. After using, we recommend immediately scrubbing the growler or 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 products 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 or tumbler’s interior with a long-handled bristle brush, a bit of liquid dish soap and warm water, rather than tossing it in the dishwasher.
