We recommend handwashing with mild detergent. Avoid bleach or metal scrubbers. Some Tritan models are top-rack dishwasher safe.

Most BOSS bottles and tumblers do not use glass liners — they’re made from stainless steel or Tritan for better durability.
However, our Glass Liner Thermal Carafe does feature a premium borosilicate glass inner liner, which offers several benefits:
Superior heat retention compared to stainless steel
No metallic taste, preserving the purity of your beverages
Naturally resistant to stains and odors
Ideal for tea, coffee, and long-hour thermal storage
The carafe’s outer body protects the glass liner, ensuring daily safety while delivering exceptional thermal performance.
