3 Items You Must Avoid Placing in Your Dishwasher

You’re rushing to clean up after dinner, tempted to toss everything into the dishwasher. Wait! Before you do, there’s something you should know.

Not all items are dishwasher friendly. This guide will reveal the top three culprits you should always clean by hand. Trust us, your wooden utensils, cast iron, and non-stick cookware will thank you!

The Problem With Wooden Utensils

While most of your kitchenware can handle a dishwasher’s heat and intensity, your wooden utensils certainly can’t. Their natural composition makes them susceptible to wooden warping concerns. The high temperatures and prolonged soaking lead to the wood expanding and contracting, causing it to warp. This not only ruins the shape of the utensils but also weakens them, reducing their lifespan significantly.

In addition to warping, there’s also the issue of natural oil depletion. Wooden utensils are often treated with natural oils to maintain their luster and durability. Dishwashers strip away these oils, leaving your utensils dry, dull, and vulnerable to cracking.

It’s best to handwash wooden utensils, to preserve their integrity and longevity.

Why Cast Iron Shouldn’t Be Dishwashed

Just like your wooden utensils, your cast iron cookware shouldn’t be tossed into the dishwasher either. The dishwasher’s powerful jets and hot water can lead to rust formation on the cast iron. This not only compromises the aesthetics of your cookware but also its functionality. The rust can make your food taste metallic and can even pose health risks when ingested.

Moreover, dishwashing strips away the seasoning, the protective layer that gives your cast iron its non-stick properties and enhances the flavor of your food. To maintain it, you need to clean cast iron gently by hand and regularly re-season it.

Potential Damage From Non-Stick Cookware

In addition to your cast iron, you shouldn’t toss your non-stick cookware in the dishwasher either. The dishwasher’s heat impact can gradually erode the non-stick coating, presenting non-stick coating risks. You mightn’t notice it initially, but over time, tiny particles of the non-stick surface can chip off into your food. This not only ruins your cookware but may also pose potential health risks.

Moreover, the harsh chemicals and high pressure water in your dishwasher can cause the non-stick layer to warp and deteriorate. Instead, hand washing these items with a soft sponge and mild detergent is recommended. By doing so, you’re not only preserving your non-stick cookware but also protecting your health.
