What Not to Put in Your Dishwasher

A dishwasher can be a lifesaver when it comes to kitchen cleanup. Being able to load the appliance with dirty dishes and let it handle the mess for you is a convenience that can save you a lot of time and hassle. While most kitchen essentials are safe in the dishwasher, there are many items that should be hand-washed instead of putting them in the machine. Some kitchen items, such as glass and fragile dishes, cannot withstand the high water and drying temperatures during the cycle, and they could break if they’re jostled around the dishwasher.

At Mr. Rooter Plumbing, we’ve put together a list of what you can and can’t put in the dishwasher.

Wooden Utensils and Cutting Boards

The dishwasher’s extremely hot water can cause wooden utensils and cutting boards to swell, warp, or crack. Wooden items should be hand washed with mild dish soap.

Cast Iron

The harshness of the washing cycle can damage the nonstick surface on cast iron and leave it vulnerable to rust. You can keep your cast iron pots and pans in top condition by handwashing them.

Nonstick Cookware and Ceramic Cookware

Even if your nonstick cookware is labeled "dishwasher safe," you should not put it in the dishwasher because the harshness of the washing cycle can damage the nonstick surface.

Insulated Mugs

You should keep insulated mugs out of the dishwasher because high temperatures can ruin the vacuum seal and cause the mugs to lose their efficiency.

Kitchen Knives, Blades, And Sharp-Edged Tools

Putting your knives and other sharp-edged tools in the dishwasher can dull the edges, and the edges can damage dishwasher racks and baskets. Wash your kitchen knives, blades, and sharp-edged tools carefully by hand in hot, soapy water instead.

Graters and Sieves

It’s unlikely that even the best dishwasher will remove every bit of food particles from your graters and sieves. Hand-wash your graters and sieves with a sponge and warm, soapy water.

Aluminum Pans and Cookware

Unless they’ve been anodized, aluminum pans and cookware will be discolored and dulled during a dishwasher cycle. You also risk getting dark stains all over the aluminum items, which will then transfer onto the other items in the dishwasher.

Copper Pans and Mugs

Copper is prone to tarnishing, and the harsh chemicals in dishwasher detergent can ruin the shine of your copper pans and mugs. To maintain your copper utensils’ luster, hand wash them with a mild dish soap.

Pressure Cooker Lids

You should hand wash pressure cooker lids with warm, soapy water instead of putting them in the dishwasher. Pressure cooker lids have safety valves and vents that can get clogged with food particles. The detergent can also damage the rubber or silicone seals on the lids and shorten the lifespan of your appliance.

Items You Can Clean in The Dishwasher

  • Hard plastic utensils
  • Stainless steel
  • Sturdy drinking glasses and wine glasses
  • Stoneware baking dishes
  • Metal utensils
  • Silicone utensils
  • Ceramic dishware
