A Guide to Proper Dishwashing

A dishwasher is undoubtedly a time-saving appliance that makes our lives easier by taking care of dirty dishes. However, not everything can withstand the dishwasher’s powerful cleaning cycle. While the dishwasher is a convenient and time-saving appliance, certain items are better off being hand washed. Delicate glassware, wooden utensils, cast iron cookware, nonstick pans, fine china, and insulated travel mugs all require special attention to maintain their quality and functionality. In this article, we will guide you through a list of things that should be handled with care and provide instructions on proper dishwashing techniques.

Delicate Glassware and Crystal

Delicate glassware and crystal items should never be placed in the dishwasher. The intense heat and forceful water jets can cause them to crack, chip, or become cloudy. To maintain their clarity and elegance, it’s recommended to hand wash these items using warm, soapy water. Gently rinse and dry them with a soft cloth to prevent water spots.

Wooden Utensils and Cutting Boards

Wooden utensils, such as spoons, spatulas, and cutting boards, should be kept away from the dishwasher. The prolonged exposure to hot water and steam can warp, crack, or splinter the wood, rendering them unusable. Instead, wash them by hand using mild soap and warm water. Allow them to air dry thoroughly before storing.

Sharp Knives

While it might be tempting to toss your kitchen knives into the dishwasher for a quick clean, it’s highly discouraged. The high heat and abrasive detergents can dull the blade, damage the handle, or even cause the knife to chip. It’s best to hand wash your knives with warm, soapy water and a sponge. Be sure to dry them immediately to prevent any chance of rusting.

Copper Cookware

Copper cookware is prized for its excellent heat conductivity and stunning appearance. However, it is highly reactive to the harsh chemicals found in dishwasher detergents. Placing copper pots and pans in the dishwasher can cause discoloration, tarnishing, and a loss of their shiny finish. Instead, wash copper cookware by hand using a mild copper cleaner or a mixture of lemon juice and salt. Rinse them thoroughly and dry them with a soft cloth.

Aluminum Cookware

Similar to copper, aluminum cookware can also be affected by the alkaline detergents used in dishwashers. The chemicals can cause pitting, and discoloration, and even affect the taste of your food. To preserve the quality of your aluminum cookware, wash them by hand using mild dish soap and a soft sponge. Rinse them well and dry them immediately.

Cast Iron Cookware

Cast iron cookware, including skillets and griddles, requires special care to maintain its seasoning and avoid rusting. The harsh detergents and high temperatures in the dishwasher can strip away the seasoning and cause the cast iron to rust. After each use, it’s best to hand wash these items with a gentle brush and hot water. Dry them immediately and lightly coat them with cooking oil to protect them from moisture.

Nonstick Pans

Nonstick pans are another item that should never find its way into the dishwasher. The abrasive nature of dishwasher detergents and the high heat can damage the nonstick coating, reducing its effectiveness over time. Instead, hand wash nonstick pans using a sponge or soft cloth and mild dish soap. Rinse them thoroughly and dry them with a towel to prevent water spots.

Fine China and Hand-Painted Dinnerware

Fine china, hand-painted dinnerware, or any items with delicate designs or gold/silver accents should be handled with care. The dishwasher’s intense heat and water pressure can cause the patterns to fade or wear away. To preserve their beauty, wash these items by hand using mild dish soap and warm water. Gently dry them with a soft cloth to avoid scratching or damaging the design.

Insulated Travel Mugs and Thermoses

Insulated travel mugs and thermoses are typically made of stainless steel with vacuum-sealed interiors. Placing them in the dishwasher can compromise their insulation properties and damage the vacuum seal, leading to reduced performance. Always hand wash these items using warm, soapy water, paying attention to the tight seals and delicate mechanisms. Rinse them thoroughly to remove any soap residue and allow them to air dry completely.

How to Load a Dishwasher the Right Way

  • Read the manual: Familiarize yourself with your dishwasher’s specific loading guidelines by referring to the manufacturer’s manual. Each dishwasher may have unique features and recommendations.
  • Separate and organize: Group similar items together for efficient loading. Place bowls, plates, and utensils in their designated compartments, ensuring enough space between each item for proper water circulation.
  • Load from bottom to top: Place larger items such as pots, pans, and baking sheets on the bottom rack, while glasses, cups, and delicate items go on the top rack. Be mindful of the dishwasher’s spray arms and ensure they can rotate freely.
  • Face utensils downward: Load utensils in the utensil holder or basket with the handles facing downward. This prevents injury while unloading and ensures thorough cleaning.
  • Avoid overcrowding: Overloading the dishwasher can lead to inadequate cleaning and rinsing. Leave enough space between items for water and detergent to reach all surfaces effectively.

Dishwasher Safe Items

  • Most glassware, except delicate or hand-painted ones
  • Ceramic and porcelain dishes
  • Stainless steel utensils and cookware
  • Melamine and dishwasher-safe plastics (check labels)
  • Heat-resistant oven-safe bakeware (check labels)
  • Some dishwasher-safe plastics (check labels)

Always refer to the manufacturer’s instructions or labels on items to determine their dishwasher safety.

Knowing what is and isn’t dishwasher safe and how to load a dishwasher properly can help you avoid damage to your kitchenware and ensure thorough cleaning. Be cautious when loading items such as sharp knives, delicate glassware, wooden utensils, cast iron cookware, nonstick pans, and fine china. Follow the guidelines provided, consult your dishwasher’s manual, and check item labels for specific instructions. With proper care and attention, you can enjoy the convenience of a dishwasher while keeping your kitchenware in excellent condition for years to come.
