How do I properly clean the Nuaim 30oz Ice White tumbler and flip straw lid?

Proper cleaning maintains both hygiene and the pristine Ice White appearance of your 30oz tumbler. For daily cleaning after regular water use, simply rinse the tumbler with warm water and mild dish soap, using a long-handled bottle brush to reach the bottom. The stainless steel interior is naturally antimicrobial and doesn't harbor odors, so daily washing is straightforward. The flip straw lid requires more attention since it has multiple components. At least once weekly, disassemble it completely: remove the straw from the lid, separate the silicone seal, and wash all parts individually. These components are dishwasher-safe (top rack only to avoid heat damage), or you can hand wash with warm soapy water. For the straw itself, we recommend using a small straw cleaning brush (included with some tumblers, or available separately) to remove any beverage residue inside. If you use your 30oz tumbler for coffee, tea, or smoothies, clean it more frequently to prevent flavor transfer or residue buildup. For stubborn odors or stains, fill the tumbler with warm water, add 1-2 tablespoons of baking soda, let sit overnight, then rinse thoroughly. Avoid using bleach or harsh abrasive cleaners that could damage the powder coating. The Ice White exterior can be wiped with a damp cloth—the powder coat is durable enough to resist most marks and maintains its appearance with minimal maintenance.
