Why
Double wall glass is made of borosilicate or tempered glass, which can withstand high temperatures. However, the air gap between the walls can be compromised by harsh detergents or rapid temperature changes in the dishwasher, potentially leading to cracking or loss of insulation.
How do you wash Double Wall Glass?
Hand wash with mild soap and warm water, and dry with a soft cloth. Avoid sudden temperature changes, such as pouring hot liquid into a cold glass.
