Why
The Stanley Quencher body is made of 18/8 stainless steel, which is dishwasher safe and resistant to rust and corrosion under normal conditions. However, the lid is made of Tritan copolyester, a BPA-free plastic that can withstand high heat but may warp or degrade over time in the dishwasher's high heat and harsh alkaline detergent. The silicone gasket inside the lid can degrade, lose its seal, or harbor bacteria if repeatedly machine washed. The manufacturer, Stanley, recommends hand washing the lid and straw to extend the life of the product, while the body can be placed on the top rack. Specific failure modes include lid warping, gasket seal failure, and potential decal peeling on the body if exposed to high heat or abrasive detergents.
How do you wash Stanley Quencher?
- Disassemble the lid by removing the silicone gasket and straw.
- Hand wash the lid, gasket, and straw in warm soapy water using a soft sponge.
- Rinse thoroughly to remove all soap residue.
- Wash the stainless steel body in the dishwasher on the top rack, or hand wash with a non-abrasive sponge.
- Dry all parts completely before reassembling to prevent moisture buildup.
- Reassemble the lid by inserting the gasket and straw securely.
What happens if you put Stanley Quencher in the dishwasher?
If you put the entire Stanley Quencher in the dishwasher, the stainless steel body will likely come out fine, though repeated cycles may cause the exterior powder coating to fade or peel, especially if high heat or abrasive detergents are used. The Tritan lid may warp or become cloudy after several washes, and the silicone gasket can lose its elasticity, leading to leaks. The straw, if plastic, may also warp. After one wash, you might not notice immediate damage, but after repeated washes, the lid may not seal properly, reducing insulation and causing spills. The damage is mostly cosmetic for the body but functional for the lid and gasket, as a compromised seal affects performance.
