11 Items You Shouldn’t Put in Your Dishwasher

We asked the experts for any warnings about what ought to remain out of the dishwasher. Some of what they say might shock you.

Sharp Knives

Your dishwasher may dull knife blades; therefore, wash preparation knives by hand. Even if a manufacturer’s directions say it is alright to place knives inside the dishwasher, you might cut yourself unloading and loading sharp knives; therefore, your best bet includes hand washing sharp knives.

Hollow Handled Knives

Extremely high temperatures inside the dishwasher may melt the adhesive which holds the two parts of a hollow-handled knife together. If it happens, your knife handle is going to fall apart. To keep them in top condition, hand wash them instead.

Nonstick Pats and Pots

Unless a manufacturer specifically says that something is dishwasher safe, don’t place cookware that has a nonstick coating inside the dishwasher. Over a period of time, the dishwashing process may break the coating down, and cause it to flake off while cooking and ruin the non-stick finish.

Cast Iron

This should NEVER go inside the dishwasher. It’ll take a long period of time to build up a non-stick surface on cast iron and detergents are going to strip it away and leave the cast iron pan prone to rust. Nonabrasive sponges and plain water are your best bets. Take care of such cookware and it may last for several generations.

China that has Metallic Decoration

Surprisingly, the majority of chine and porcelain dishware is dishwasher safe. However, if your dinnerware features metallic trim or images, hand wash it, so you can prevent damage to its decorations. In addition, remember that china might become chipped if it accidentally touches other dishes within the dishwashing cycle; therefore, carefully load your dishwasher.

Antiques and Additional Fragile Items

Fragile items like antiques, hand-blown glass, and fine figurines should remain out of your dishwasher. If it is a family heirloom or priceless, wash it by hand.

Hand-Painted Stoneware and Ceramics

Unless you want your artwork to go down the drain over a period of time, you ought to hand wash such items.


After repeated washings, some lead crystal might etch (become pitted and cloudy). To be safe, always make sure that you follow the manufacturer’s directions.

Insulated Travel Mugs, Drinkware, and Pitchers

The issue here is that extremely high temperatures inside the dishwashing cycle might damage the vacuum seal. It is better to hand wash these items.

Anything that has a Paper Label

Dishwashers may loosen and remove labels from jars and bottles. Such pieces of paper may lodge the dishwasher’s drain or stick to other dishes and create a messy clean up issue. Always remove labels before placing them in the dishwasher.

Dishes that Have Large Pieces of Food on Them
It may go without saying, yet large pieces of food may clog your dishwasher drain or wind up on otherwise clean dishes.
