Is Stanley Cup dishwasher safe?
Dishwasher safe✓ Verified
Yes — Stanley says all Quenchers are dishwasher safe, though hand washing helps preserve the exterior finish.
Why
Stanley's official care guidance states the Quencher H2.0 (and the rest of the Quencher line) is dishwasher safe. The 18/8 stainless steel and FlowState lid hold up to wash cycles; over many high-heat cycles the powder-coated finish can dull, which is why some people still hand wash. Very old classic Stanley bottles are the exception and should be hand washed.
How to wash it
Dishwasher safe — separate the lid and straw and wash all parts. To best preserve the colored finish, hand wash with mild soap and dry promptly.
