The household dishwasher is one of the great inventions of our time. It saves you from countless hours spent up to your elbows in soapy water, while also conserving water and sanitizing your dishes. An added bonus is a clutter-free kitchen, as dirty dishes can be hidden away inside the washer instead of piled up in your sink. Unfortunately, there are some kitchen items that just don’t belong in the dishwasher. So, fill up your sink with hot, soapy water, get out those rubber gloves, and wash these items by hand.
13. Sharp Knives
To protect your sharp, high-quality knives from the dulling effects of the dishwasher, wash these items by hand. Abrasive dishwasher detergent can wreak havoc on your knives. Tumbling and crashing against other silverware dulls the knives as well. Additionally, there is the danger factor of reaching into the dishwasher and grabbing a knife blade when emptying the washer. To protect your knives, wash them by hand in hot, soapy water and hand dry with a tea towel. To further protect the sharpness of your knives, store them in a knife block or in blade guards.
Repeated washings in the dishwasher can leave your crystal goblets anything but crystal clear. According to GE Appliances, the phosphates present in dishwashing detergent can cling to the glass. Over time, they etch into the crystal, removing metal ions from the surface. The milky residue left behind on the surface of the glass cannot be removed. To avoid drinking from cloudy, pitted crystal goblets, wash your crystal by hand in warm, soapy water. Use rubber gloves to prevent dropping and breaking your fine crystal.
