Can Mason Jars Go in Dishwasher: A Complete Guide

Mason jars have become a staple in many households, serving various purposes from food storage to DIY crafts. One common question that often arises is whether these versatile containers can be safely placed in the dishwasher. In this article, we’ll explore the ins and outs of washing Mason jars in the dishwasher, addressing concerns about their durability, safety, and potential alternatives.

Understanding Mason Jars

Mason jars are typically made of glass and are designed to withstand various temperature extremes. They are known for their durability and versatility, making them a popular choice for preserving foods, beverages, and even serving as creative décor pieces.

Advantages of Using Dishwashers

Dishwashers offer convenience and efficiency in cleaning various kitchen items. They use high water temperatures and strong detergents to remove dirt and grime effectively, potentially saving time and effort.

Concerns About Dishwashing Mason Jars

While Mason jars are robust, certain factors need consideration when contemplating dishwashing them. One primary concern is the potential impact on the jar’s seal and lid.

Impact on Jar Seal and Lid

The heat and pressure in dishwashers might compromise the integrity of the jar’s seal, which is crucial for preserving food. Additionally, the high water pressure could dislodge the lids, affecting their ability to create an airtight seal.

Avoiding Thermal Shock

Mason jars, like other glass items, are susceptible to thermal shock – sudden temperature changes that can cause the glass to crack. Placing a cold jar in a hot dishwasher or vice versa increases this risk.

Proper Disassembly Before Washing

Before placing Mason jars in the dishwasher, it’s essential to disassemble them. Remove the lid and any additional parts, such as rubber gaskets, to ensure thorough cleaning and prevent potential damage.

Using Mild Detergents

Opt for mild, eco-friendly detergents to avoid harsh chemicals that could degrade the glass or affect the seals. Avoid using abrasive scrubbers that might scratch the glass surface.

Alternatives to Dishwashing

If you’re hesitant about dishwashing your Mason jars, consider handwashing as an alternative. This allows you to have more control over the cleaning process and reduces the risk of potential damage.

Cleaning Stubborn Stains

For stubborn stains, a mixture of baking soda and water can work wonders. Gently scrub the stained areas with a soft cloth or sponge to maintain the jar’s appearance.

Longevity of Mason Jars

Proper care, whether through handwashing or using a dishwasher, can extend the lifespan of your Mason jars. Regularly inspect the jars for any signs of wear and tear.

Preserving Labels and Designs

If your Mason jars have labels or decorative designs, the dishwasher’s high heat and pressure might cause these elements to peel or fade. Handwashing is a safer option to preserve these aesthetic features.

When Dishwashing Is Not Recommended

Certain Mason jars, particularly vintage or delicate ones, should not be put in the dishwasher at all. It’s advisable to research the specific type of jar you have to ensure its safe cleaning.

Ensuring Proper Drying

After washing, ensure that the Mason jars are thoroughly dried, both inside and out. Trapped moisture could lead to mold growth or other issues.

Storing Mason Jars After Washing

Store your Mason jars in a cool, dry place away from direct sunlight. This prevents unnecessary exposure to heat or humidity that could impact the jar’s quality.


In conclusion, Mason jars can generally go in the dishwasher, but with precautions. Disassembling the jars, using mild detergents, and being mindful of temperature changes are crucial steps to ensure their longevity. However, for precious or delicate jars, handwashing remains the safer option to preserve their integrity and aesthetic appeal.
