How should I clean the Pastel Mint tumbler to maintain the beautiful color?

Proper cleaning maintains both the hygiene and the beautiful Pastel Mint aesthetic of your 30oz tumbler for years. For daily cleaning after regular water use, simply rinse the tumbler with warm water and add a small amount of mild dish soap. Use a long-handled bottle brush to reach the bottom and scrub the interior—the wide 7.5cm mouth opening provides easy access. The 18/8 stainless steel interior is naturally antimicrobial and doesn't absorb odors or stains, so daily washing is straightforward. Rinse thoroughly with warm water and either air dry upside down or hand dry with a clean towel. For the Pastel Mint powder-coated exterior, we recommend hand-washing rather than dishwasher use. While the stainless steel itself is dishwasher-safe, repeated exposure to harsh dishwasher detergents and high heat (65-80°C) can, over many months of cycles, potentially affect the vibrancy and texture of powder-coated finishes. Hand-washing takes just 60 seconds and preserves the soft, beautiful Pastel Mint appearance that makes this tumbler special. Simply wipe the exterior with a damp soapy cloth or sponge, rinse, and dry. The flip straw lid requires more attention and is dishwasher-safe (top rack only). For daily use, rinse the lid under running water and use a small straw cleaning brush to clean inside the straw tube. At least once weekly, disassemble the lid completely: pull the silicone straw out from the top, separate the silicone seal from the lid, and wash all three components individually with warm soapy water or place them in the dishwasher's top rack. This prevents any beverage residue buildup and ensures optimal sealing performance. If you use your tumbler for coffee, tea, or smoothies (anything other than plain water), increase cleaning frequency to prevent flavor transfer or residue accumulation. For stubborn stains or odors in the tumbler interior, fill with warm water, add 1-2 tablespoons of baking soda, let sit for 30-60 minutes, then scrub with a bottle brush and rinse thoroughly. Avoid using bleach, harsh abrasive cleaners, or scouring pads that could scratch the stainless steel or damage the powder coating. With this simple care routine, your Pastel Mint tumbler will maintain its pristine appearance and perform flawlessly for a decade or more.
