Why
The Zojirushi SM is a stainless steel vacuum insulated bottle with a nonstick interior coating. The high heat and harsh detergents in dishwashers can damage the vacuum seal and degrade the nonstick coating, leading to reduced insulation performance and potential flaking.
How do you wash Zojirushi SM?
Hand wash with mild soap and warm water using a soft sponge. Rinse thoroughly and air dry with the cap off to prevent odors.
