Is Pyrex Containers dishwasher safe?
Sometimes — with care
Pyrex containers are generally dishwasher safe, but hand washing is recommended to preserve the clarity and longevity of the glass.
Why
Pyrex is made of tempered glass, which can withstand dishwasher heat cycles. However, harsh detergents and high heat may cause clouding or etching over time. The manufacturer recommends placing them on the top rack and avoiding extreme temperature changes.
How to wash it
For best results, hand wash with mild detergent and a soft sponge. If using a dishwasher, place on the top rack and allow to cool completely before rinsing.
