Can Pyrex Dishes Go in the Dishwasher

In today’s fast-paced world, convenience is key when it comes to daily chores like washing dishes. Pyrex dishes have long been a staple in many kitchens due to their versatility and durability. But can you toss these iconic glass containers into the dishwasher without fear of damage? In this article, we’ll explore the ins and outs of cleaning Pyrex dishes in the dishwasher, providing you with valuable insights and tips to ensure your kitchenware remains in tip-top condition.

Pyrex dishes have been a kitchen favorite for generations, thanks to their ability to handle extreme temperatures and resist staining and odors. However, when it comes to cleaning, many people wonder if they can simply place their Pyrex dishes in the dishwasher.

Understanding Pyrex Glass

Pyrex glass is known for its exceptional durability and heat resistance. It can withstand both high and low temperatures, making it perfect for baking, cooking, and storing food. Pyrex dishes are made from tempered glass, which is less likely to shatter compared to regular glass.

Dishwasher Safety

The good news is that most Pyrex dishes are dishwasher safe. Manufacturers understand the need for convenience and have designed their products to withstand the rigors of the dishwasher cycle. However, there are some essential considerations to keep in mind.

Hand Washing vs. Dishwasher

While Pyrex dishes can generally handle the dishwasher, some experts recommend hand washing to prolong their lifespan. Hand washing allows you to control the water temperature and avoid harsh detergents that may affect the glass over time.

Pyrex Lids and Dishwashers

Pyrex lids, especially those with plastic components, may not fare as well in the dishwasher. High heat and strong detergents can cause the plastic to deteriorate. It’s often best to wash these lids by hand.

Avoiding Thermal Shock

One potential risk of using a dishwasher for Pyrex is thermal shock. This occurs when the glass undergoes rapid temperature changes, which can lead to cracking or breaking. To avoid this, allow your Pyrex dishes to cool down before placing them in the dishwasher.

Regular Maintenance

To keep your Pyrex dishes in pristine condition, regularly inspect them for signs of damage, such as chips or cracks. Replace any damaged dishes promptly to prevent accidents.

Alternatives to Dishwashing

If you’re concerned about using the dishwasher, you can always opt for hand washing. Use a mild dish soap and a soft sponge or cloth to clean your Pyrex dishes gently.

Common Misconceptions

There are a few common misconceptions about Pyrex and dishwashers. Some believe that dishwashing can cause Pyrex to lose its clarity or become cloudy. However, this is typically due to hard water and can be resolved with vinegar or citric acid treatments.

Cleaning Tough Stains

Stubborn food stains can be challenging to remove, even from Pyrex. A mixture of baking soda and water applied to the stained area can help lift the residue. Let it sit for a few minutes before scrubbing.

Storing Pyrex Safely

When storing Pyrex dishes, ensure they are dry and free from any food residue. Stack them carefully to prevent chipping or scratching.


In conclusion, Pyrex dishes can generally go in the dishwasher, but some precautions are necessary. Hand washing is an excellent alternative if you want to extend the life of your Pyrex kitchenware. By following these guidelines, you can enjoy the convenience of a dishwasher without compromising your beloved Pyrex dishes.
