Dishwashers are timesavers in the kitchen. However, some dishes should not be washed in them. They include: • Hollow-handled knives: The adhesive that holds the hollow-handled knives together will melt away if you put them in a dishwasher, causing them to fall apart. Therefore, we recommend hand washing to ensure that they last long. • Sharp knives: Some manufacturers may advise you to wash your knives in the machine. However, this is not recommended as it will dull the knife blades. You may also cut yourself while loading and unloading the knives; hence it is best to hand wash them. • Nonstick pots and pans: Do not put nonstick pans and pots in the dishwasher unless the manufacturer says otherwise. The washing process may break down the coating causing it to flake off and ruin the nonstick finish. • Ceramic Cookware: Always hand washes your ceramic cookware as the dishwasher detergents may contain citric acids, which are too harsh and will destroy the finish. • Cast Iron Cookware: Whatever the case, never put a cast iron utensil in the dishwasher. The dishwashing detergents will strip away the nonstick surface and leave the pan vulnerable to rusting. The best way to take care of it is to wash it with plain water and nonabrasive sponges. Wooden Spoons And Cutting Boards: Wooden cutting boards, spoons, and utensils with wooden handles should not be put in the dishwasher. The hot water can warp and crack the wood and even damage the wooden finish on the utensils. It will strip the natural oils that keep the wooden items from drying out; thus, they will begin to crack. For these, only hand wash them with a mild detergent and warm water. • Pressure Cooker lids: Pressure cooker lids should not be put in the dishwasher as the tiny food particles or detergent might collect in the regulator and safety valves, causing the cooker to malfunction. Also, the harsh chemicals can damage the silicone or rubber seals of the lid. Therefore, when washing these pressure cooker tops and pots, do so by hand and use warm and soapy water. Avoid storing with the top in place as the gasket might seal permanently. • Graters And Sieves: Graters and sieves should not be put in the dishwasher as they will remove the plastic coating on the racks, leading to rust. • Aluminum cookware: Aluminum can be easily stained with hot water and harsh dishwashing detergents. You may see some white spots on the surface due to the alkalinity of the dishwashing detergent. They can also mark other items as they move around in the dishwasher during the wash cycle. Therefore, even though it is labeled “dishwasher safe” it is better to hand wash. To remove the discoloration and spots, make a paste of warm water and cream of tartar and spread it over the pot.
