How should I clean the Blush Pink tumbler to maintain the beautiful color?

Proper cleaning maintains both hygiene and the exquisite Blush Pink aesthetic of your 30oz tumbler for years of beautiful use. 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, soft towel. For the Blush Pink powder-coated exterior, we strongly 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 typical dishwasher temperatures) can, over many months of cycles, potentially affect the vibrancy and smooth texture of powder-coated finishes. Hand-washing takes just 60 seconds and preserves the soft, beautiful Blush Pink appearance that makes this tumbler special. Simply wipe the exterior with a damp soapy cloth or soft sponge, rinse with clean water, and dry with a soft towel. Avoid abrasive sponges or scouring pads that could scratch the finish.
