How to Care for Your Stanley 30oz ProTour Tumbler

Quick answer

Hand-wash your Stanley 30oz ProTour Tumbler with warm soapy water after each use, and deep clean the lid and straw weekly to prevent mold and maintain the leakproof seal.

Step-by-step care routine

1. 1. Rinse after every use: As soon as you finish your drink, remove the lid and rinse the tumbler body and lid with warm water. This prevents residue from drying and sticking. For coffee or tea, a quick rinse with a drop of dish soap is even better. Don't let the tumbler sit empty for hours before rinsing; dried-on residue is much harder to remove.
2. 2. Hand-wash the lid and straw weekly: Fill a bowl with warm water and a few drops of mild dish soap. Submerge the lid and straw, then use a small brush (a straw-cleaning brush works best) to scrub inside the straw and around the flip mechanism. Rinse thoroughly with warm water. Avoid using abrasive sponges that could scratch the plastic. Never put the ProTour lid in the dishwasher; high heat can warp the plastic and ruin the leakproof seal.
3. 3. Deep clean the tumbler body monthly: For a thorough clean, fill the tumbler with a mixture of warm water and one tablespoon of baking soda or white vinegar. Let it soak for 15 minutes, then scrub with a soft bottle brush. Rinse several times to remove all traces of the cleaning agent. This removes any lingering odors or stains. If you notice a metallic taste, rinse with a baking soda solution first; it neutralizes odors without leaving a chemical aftertaste.
4. 4. Dry completely before storing: After washing, shake off excess water and place the tumbler upside down on a drying rack. Leave the lid off and the straw open so air circulates inside. Do not reassemble until all parts are completely dry to prevent mold growth. A damp lid gasket is a breeding ground for mold; check the rubber seal inside the lid and dry it with a paper towel if needed.
5. 5. Inspect the lid seal regularly: Once a month, examine the silicone gasket inside the lid for cracks, tears, or flattening. If the seal looks worn, contact Stanley for a replacement gasket. A damaged seal is the most common cause of leaks. If your tumbler starts leaking when the flip straw is closed, the gasket is likely the culprit, not the lid itself.
