Kitchenware you should never put in your dishwasher

Dishwashers make our life so easy. However, it is important to know that some items should never be washed in the dishwasher. While most everyday kitchenware generally is safe for dishwashers, there are items that are best washed by hand.  

Always check for dishwasher-safe markings on your dishes. Dishwasher detergents are highly alkaline and can damage some fragile materials. There are also items that cannot withstand high heat and water pressure. Read on to learn which kitchenware to avoid putting in the dishwasher.

Non-stick pots and pans

The abrasive particles in dishwasher detergents could damage the non-stick layer, which makes non-stick items dangerous for usage since poisoning elements for the coating can go into the food.

Cast iron, enameled cast iron

Harsh detergents, in combination with high water pressure and temperature, will remove the necessary thin oil layer, that cast iron forms over time, and that gives its non-stick properties.  

Antique, metal-rimmed and had painted kitchenware and fine china

Easy to remember “hand-painted equals hand-washed”. High water pressure, abrasive particles from detergents and high temperature could damage these delicate items.

Cristal, hand-blown or hand painted glass

Dishwasher detergents can strip away their sheen or cause yellowing, etching or breakage of these delicate kitchenware. Everyday wine and drinking glasses are fine for dishwashers.

Cooper and aluminum items

Dishwasher detergents can make decoloring or tarnish with dark stains aluminum and cooper items.

Thin plastic

Hard plastic items can be placed in dishware if are indicated as “dishwasher safe”. Always place such items on the top rack. Items from thin plastic and disposable items should not be washed in a dishwasher since they run the risk of melting.

Wooden items

The high temperature and humidity in the dishwasher can cause swell, warp, or crack on wooden kitchenware.

Silver items

The silver metal could react with some ingredients in dishwasher detergents which can lead to tarnishing.

Sharp knives

The dishwasher can dull knife blades, so better to wash your high-quality and expensive knives by hand.

Pressure cooker lids

Thin particles of food or detergent could jam the lid’s safety valves, which could lead to serious malfunctioning or safety issues.  

Anything with a paper label

Remnants of paper and glue could clog your dishwasher’s filter. Always remove any label and trace of glue on your repurpose items before putting them in the dishwasher.
