How do I clean the 30oz tumbler?

For daily cleaning, rinse the 30oz tumbler with warm soapy water using a long-handled bottle brush. The stainless steel interior doesn't retain odors or stains. The flip straw lid can go in the dishwasher (top rack) or be hand-washed. Once weekly, remove the straw and seals for thorough cleaning. For stubborn odors, fill with warm water and 1-2 tablespoons of baking soda, let sit 30 minutes, then rinse. Hand-washing the tumbler body helps preserve any exterior finish. This simple routine keeps your tumbler hygienic and performing optimally.
