Is Pyrex Dish dishwasher safe?
Sometimes — with care
Pyrex dishes are generally dishwasher safe, but hand washing is recommended to preserve the longevity of the glass.
Why
Pyrex is made of tempered glass, which is durable and can withstand dishwasher heat cycles. However, the dishwasher's harsh detergents and high heat can cause clouding or etching over time, and sudden temperature changes may lead to breakage.
How to wash it
Hand wash with mild detergent and a soft sponge to avoid scratches. If using a dishwasher, place on the top rack away from heating elements and let cool completely before washing.
