Is Zojirushi Mug dishwasher safe?
Sometimes — with care
Zojirushi mugs are generally not recommended for the dishwasher.
Why
Zojirushi mugs are typically made of stainless steel with a vacuum-insulated construction and a nonstick interior coating. The high heat and harsh detergents in dishwashers can damage the nonstick coating and degrade the vacuum seal over time, reducing insulation performance.
How to wash it
Hand wash with mild detergent and a soft sponge. Rinse thoroughly and dry immediately to maintain the mug's insulation and coating.
