What Cannot Go In the Dishwasher

Dishwashers, our modern kitchen companions, have revolutionized the way we handle dishes. The convenience they offer is unparalleled, but not everything is meant to take a spin in the dishwasher. Knowing what cannot go in the dishwasher is crucial to preserving your kitchen essentials.

What Cannot Go In the Dishwasher?

In the hustle and bustle of daily life, dishwashers have become lifesavers. They promise not only cleanliness but also a precious commodity—time. However, the dishwasher is not a magical solution for all things dirty. There are items that simply cannot withstand the dishwasher’s forceful cleaning cycles. Let’s dive into the do’s and don’ts of dishwasher usage.

Common Dishwasher-Safe Items

Before we explore the forbidden territory, it’s essential to acknowledge the dishwasher-friendly items. Plates, glasses, and most utensils are safe for a joyride in the dishwasher. The convenience of loading up your dishwasher with these everyday items is undeniable.

Materials Matter: What to Watch For

The materials of your kitchenware play a pivotal role in determining their dishwasher compatibility. Delicate materials like certain plastics and crystal can suffer damage or discoloration, making it imperative to choose the hand-wash route.

Kitchen Utensils: Sorting the Dishwasher-Safe from the Not

Navigating the realm of kitchen utensils can be tricky. While sturdy spatulas and metal ladles can endure the dishwasher’s power, wooden utensils and delicate items like cheese graters demand a gentler touch.

Fine China and Delicate Glassware

That delicate china inherited from grandma and the fancy crystal glasses deserve your tender care. The high water pressure and intense heat in dishwashers can lead to chipping and clouding, robbing these items of their luster.

Wooden Wonders: Wooden Utensils and Cutting Boards

Wooden kitchen tools bring warmth to the kitchen, but they shun the dishwasher. The harsh conditions can cause warping and splintering, turning your cherished wooden spoons into mere relics of their former selves.

Cast Iron and Non-Stick Pans: No Dishwasher Love

While the temptation to toss everything into the dishwasher is real, resist it when it comes to cast iron and non-stick pans. Harsh detergents and high temperatures can strip these pans of their seasoned coating, rendering them less effective.

Electrical Appliances: A Big No-No

It should go without saying, but electrical appliances and dishwashers don’t mix. The intricate electronics and wiring in items like blenders and toasters are not designed to endure the dishwasher’s watery onslaught.

The Nitty-Gritty of Dishwasher Filters

Maintaining your dishwasher’s efficiency is not only about what goes in but also what stays out. Regularly cleaning the dishwasher filter prevents debris buildup and ensures your dishwasher runs smoothly.

Hidden Culprits: Items with Hidden Components

Be wary of items with hidden parts, like travel mugs with detachable lids or pepper grinders. These components might not fare well in the dishwasher, and disassembling before washing is the key to their longevity.

Maximizing Dishwasher Efficiency

Loading your dishwasher strategically is an art. Place items strategically for optimal cleaning, use the right detergent, and consider adding rinse aid to enhance drying and prevent water spots.

Environmental Impact: Dishwashing Dilemma

While dishwashers save water compared to handwashing, their environmental impact is not negligible. Balancing convenience with environmental responsibility involves choosing energy-efficient models and running full loads.

DIY Dishwasher-Safe Test

Curious if an item can withstand the dishwasher’s might? Conduct a simple DIY test. Submerge the item in a bowl of hot, soapy water for a few minutes. If it comes out unscathed, it’s likely dishwasher-safe.

The Aftermath: Dealing with Dishwasher Mishaps

Mistakes happen. If you’ve accidentally subjected a non-dishwasher-safe item to the machine, act promptly. Remove the item and assess the damage. For plastics, check for warping; for delicate items, inspect for cracks. Immediate action can sometimes salvage the situation.


In the world of dishwashers, not everything is fair game. Knowing what cannot go in the dishwasher is essential for preserving your kitchen treasures. As you revel in the convenience of this modern appliance, remember to be discerning. Hand-washing certain items might take a bit more time, but the longevity of your kitchen essentials is well worth the effort.
