Is Stainless Steel Water Bottle dishwasher safe?
Sometimes — with care
Stainless steel water bottles are generally dishwasher safe, but hand washing is recommended to preserve insulation and finish.
Why
Most stainless steel bottles are made of durable 18/8 or 304 stainless steel, which can withstand dishwasher heat. However, the high heat and harsh detergents in dishwashers can damage vacuum insulation, exterior coatings, or paint over time. Many manufacturers advise hand washing to extend the bottle's lifespan.
How to wash it
Hand wash with warm soapy water and a soft sponge. Rinse thoroughly and air dry upside down with the cap off.
