Can You Put Pyrex In The Dishwasher: A Guide to Glassware Care

In today’s fast-paced world, convenience is key. When it comes to kitchenware, many of us rely on dishwashers to make our lives easier. But what about Pyrex, that beloved glassware known for its durability and versatility? Can you put Pyrex in the dishwasher without risking damage? In this article, we will explore the dos and don’ts of caring for your Pyrex in the dishwasher and provide you with some valuable tips to ensure your glassware stands the test of time.

Pyrex, a household name in glassware, has been a staple in kitchens for generations. Renowned for its ability to withstand extreme temperatures and resist staining, Pyrex is a favorite among cooks and bakers. However, there’s an ongoing debate about whether it’s safe to put Pyrex in the dishwasher.

Understanding Pyrex

Before we delve into the dishwasher dilemma, let’s understand what Pyrex is made of. Pyrex glass is crafted from borosilicate, a type of glass known for its exceptional strength and resistance to thermal shock. This means it can go from the freezer to a hot oven without shattering. Its durability is one of the reasons it’s so beloved.

The Dishwasher Dilemma

Many people wonder if they can toss their Pyrex dishes in the dishwasher along with their other kitchen items. After all, it would make cleanup a breeze. The answer, however, isn’t a simple yes or no.

The Pros and Cons


  • Check the Label: Look for any specific instructions on your Pyrex. Some newer Pyrex products are made from soda-lime glass, which is more susceptible to thermal shock. These should be hand-washed.
  • Use the Top Rack: If you decide to use the dishwasher, always place your Pyrex on the top rack to minimize exposure to intense heat.
  • Skip Heated Dry: Avoid the heated dry option, as the sudden temperature change can stress the glass.
  • Use Mild Detergent: Opt for a gentle, non-abrasive detergent to protect the glass’s surface.


  • Avoid Overcrowding: Don’t cram your dishwasher with too many items. This can lead to potential chipping or cracking.
  • No Sudden Temperature Changes: Never transfer hot Pyrex directly into cold water or vice versa. This can cause thermal shock, leading to breakage.
  • Say No to Abrasives: Don’t use abrasive scrubbers or harsh chemicals on Pyrex, whether in the dishwasher or during handwashing.
  • Old vs. New Pyrex: Older Pyrex items are more likely to withstand dishwasher use. Newer versions may be more delicate.

Hand Washing vs. Dishwasher: Which is Better?

If you’re unsure about the dishwasher, hand washing is always a safe bet. It allows you to exercise greater control over the temperature and handling of your Pyrex.

Maintaining Pyrex’s Clarity

Over time, Pyrex glass can become cloudy. To maintain its clarity, try using a mixture of vinegar and water for cleaning. This natural solution can help restore its shine.

Handling Stubborn Stains

For stubborn stains, make a paste using baking soda and water. Apply it to the stained area, let it sit for a while, and then gently scrub with a soft cloth or sponge.

Dealing with Heat Shock

To avoid heat shock, never place a Pyrex dish directly from the oven onto a cold surface. Instead, allow it to cool down on a heat-resistant pad or a dry towel.

Storing Pyrex Safely

Store your Pyrex items carefully, making sure they are not stacked too tightly to prevent chipping. Use soft padding or cloth between stacked items for added protection.

Longevity Tips

To extend the life of your Pyrex, avoid extreme temperature changes, refrain from using it on direct flame, and handle it with care.

Eco-Friendly Alternatives

If you’re concerned about the environmental impact of dishwashers, consider hand washing as a more eco-friendly option.


In conclusion, while it is possible to put Pyrex in the dishwasher, it’s essential to do so with care. Always check the label, use the top rack, and avoid sudden temperature changes. However, for the best longevity and clarity, consider hand washing as your primary method for cleaning Pyrex.
