Can Mason Jars Go In The Dishwasher?

Mason jars have become a versatile and popular choice for storage, organization, and crafting. If you are curious if your beloved Mason jars can withstand the dishwasher, worry not because most Mason jars can go in the dishwasher! But remember to always check the manufacturer’s specifications just to be sure. Their durable glass construction typically allows for machine washing without any adverse effects.

This article explores the compatibility of Mason jars with dishwashers, suitable placement in the dishwasher, and cleaning, and sterilization processes for its mason jar parts. Let’s get started!

Deciphering Dishwasher Safety for Mason Jars

Delving into the factors that make a jar dishwasher safe, it’s worth noting that sturdiness and industrial design largely define a product’s safety in these machines. Mason jars, revered for their durability, fit this category quite well. Their thick glass construction is not easily susceptible to the high temperature and pressure exerted in a dishwasher.

However, not all mason jars are created equal. Standard mason jars mostly share a common trait of dishwasher safety, but specialty or artisan mason jars might not share the same resilience. Some of these could feature hand-painted designs, ornate decorations, or other enhancements that may not withstand a dishwasher’s vigorous cleaning process. As a safety precaution, always check the manufacturing details or consult the user manual to ensure that your specific type of mason jar is dishwasher-safe.

Suitable Placement and Care in the Dishwasher

Suitable placement and careful handling can greatly augment the longevity of mason jars in the dishwasher. The principle is to keep the jars secure, yet well-spaced to ward off any potential damage caused by movement during cleaning cycles.

Here are some tips to achieve optimum placement and care:

  • Always place mason jars on the top rack where the water pressure is gentler. This can prevent potential cracking or breakage.
  • Position each jar upright to allow water and detergent to circulate effectively and assure optimum cleaning.
  • Ensure that mason jars are not packed tightly together. Overcrowding can instigate collision between jars, leading to possible breakage. Leave decent space between jars to avoid this.
  • Before placing them in the dishwasher, ensure the jars are devoid of any food residue or stubborn stains. Briefly rinse them under hot water – this will assist in easier cleaning and sterilization.

The Debate Around Mason Jar Lids and Dishwasher Safety

A widely debated topic amongst mason jar enthusiasts circles around the dishwasher safety of their corresponding lids. The dilemma arises due to the diverse range of materials used to manufacture the lids – from plastic to various types of metal, each with its own dishwasher suitability.

Here are some points to consider regarding mason jar lids and dishwashers:

  • Metal lids, commonly used with mason jars, are known to rust over time. The dishwasher’s moist and hot environment can potentially expedite this process, leading to deterioration and functional failure of the lids.
  • If the lid has a rubber seal, which aids in preserving the jar content’s freshness, dishwashing can harm these components. High heat and intense cleaning can wear out or warp the seal.
  • Lastly, some lid decorations or labels may not survive a dishwasher cycle. These could become discolored, peel off, or completely wash away.

Because of these concerns, many people recommend hand-washing mason jar lids. This approach adds a bit of work, but it can help extend the lifespan of your lids and keep them in good functioning order.

Cleaning Damages and Sterilization Procedures

When it comes to the potential damages associated with dishwashing mason jars, there are a few noteworthy aspects. While the sturdy structure of these jars typically stands up well to intense dishwasher cycles, issues might arise with certain types of decorations or painted details that could chip or fade. Overly packed jars might also collide with each other during the washing process, causing chips, cracks, or even shattering.

Now let’s discuss sterilization. This is a crucial stage particularly for those planning to use their mason jars for preserving or canning food. Dishwashers can be highly effective at sanitizing mason jars due to their high-temperature wash and dry cycles. To ensure proper sterilization:

  • Always use high-quality detergent.
  • Opt for the ‘heated dry’ setting or cycle to ensure high temperatures which aid in sterilization.
  • Lastly, for complete peace of mind, consider running an empty cycle initially to ensure the optimal level of cleanliness inside your dishwasher before you start sterilizing your mason jars.


In conclusion, mason jars generally hold up well in the dishwasher, being durable and built for intense conditions. Also, remember a dishwasher is not just for cleaning; it serves as a sterilizing tool for those of us inclined toward preserving or canning. This combination of careful handling and savvy use of the dishwasher can make your mason jar cleaning task simpler and more efficient. Safe and effective cleaning practices will help in prolonging the life of your jars, so they can continue to serve their myriad roles in our kitchens and our homes.
