How to Clean Stanley Quencher 20oz H2.0 FlowState Tumbler

Quick answer

To clean your Stanley Quencher 20oz H2.0 FlowState Tumbler, disassemble the lid and straw, wash each part with warm soapy water, and dry thoroughly before reassembling. Avoid the dishwasher for best results.

Step-by-step cleaning process

1. Disassemble the lid and straw: Twist the FlowState lid counterclockwise to remove it. Pull the reusable straw out and separate the silicone gasket from the lid. Also remove the silicone cover over the drinking spout. Don't skip the small silicone parts—they trap residue.
2. Wash each part with warm soapy water: Use mild dish soap and a soft sponge or bottle brush. Scrub the lid's crevices, the straw inside and out, and the tumbler body. Rinse thoroughly with clean water. Avoid abrasive scrubbers; they can scratch the finish.
3. Dry completely before reassembly: Shake off excess water and let all parts air-dry on a clean towel. Ensure the lid's silicone gasket and straw are fully dry to prevent mold. Reassemble once dry. If you smell mustiness, moisture is still trapped—dry longer.
