What Not to Put in a Dishwasher: Essential Tips to Know

Your dishwasher is a powerful tool that saves time and effort in the kitchen, but it’s important to know what not to put in a dishwasher to avoid damage to both your dishes and the appliance itself. At Appliances 4 Less (www.a4l.com), we’re here to help you protect your kitchen items and ensure your dishwasher remains in top condition. Here’s a guide to what should stay out of your dishwasher and why.

What Not to Put in a Dishwasher

Wooden Utensils and Cutting Boards

  • Why Not: Wooden items can warp, crack, or lose their finish when exposed to the high heat and moisture inside a dishwasher. The harsh environment can also strip away the natural oils that keep the wood in good condition, leading to a shorter lifespan for your wooden utensils and cutting boards.
  • Tip: Hand wash wooden items with mild soap and water, and dry them immediately to maintain their quality.

Nonstick Cookware

  • Why Not: The nonstick coating on cookware can degrade over time when repeatedly exposed to high temperatures and harsh detergents in the dishwasher. This can cause the coating to peel or lose its nonstick properties, making your cookware less effective and potentially unsafe.
  • Tip: To extend the life of your nonstick cookware, wash it by hand using a soft sponge and gentle detergent.

Cast Iron Pans

  • Why Not: Cast iron pans are known for their durability, but they should never be placed in the dishwasher. The combination of water, detergent, and high heat can strip away the seasoning, leading to rust and damage to the pan’s surface.
  • Tip: Clean your cast iron pans by hand, using a stiff brush and hot water. Dry them thoroughly and reapply a light layer of oil to maintain the seasoning.

Sharp Knives

  • Why Not: Dishwashing sharp knives can dull their edges and cause the blades to chip or corrode over time. The agitation of the dishwasher can also lead to nicks in the knife’s surface, reducing its effectiveness.
  • Tip: Wash sharp knives by hand with warm, soapy water, and dry them immediately to prevent rust and maintain their sharpness.

Crystal and Delicate Glassware

  • Why Not: Crystal and delicate glassware can become etched, cloudy, or even crack in the dishwasher due to the high temperatures and abrasive detergents. The delicate nature of these items makes them more susceptible to damage.
  • Tip: Hand wash crystal and delicate glassware with a mild detergent and soft cloth, then dry them gently to avoid spots and streaks.

Copper Cookware

  • Why Not: Copper cookware can tarnish and lose its shine when placed in the dishwasher. The detergent can cause the copper to corrode, leading to a dull and discolored appearance.
  • Tip: Clean copper cookware by hand using a gentle cleanser specifically designed for copper. Avoid abrasive sponges or brushes that can scratch the surface.

Aluminum Cookware

  • Why Not: Aluminum cookware can react with dishwasher detergent, causing it to discolor or develop a dull finish. The high heat can also lead to warping or pitting, reducing the cookware’s effectiveness.
  • Tip: To keep aluminum cookware looking its best, wash it by hand with a mild detergent and a soft sponge.

Insulated Mugs and Bottles

  • Why Not: Insulated mugs and bottles are designed to keep liquids hot or cold for extended periods, but the dishwasher’s high temperatures can damage the vacuum seal. This can cause the insulation to fail, rendering the item less effective.
  • Tip: Hand wash insulated mugs and bottles with warm, soapy water, and let them air dry to preserve their insulation properties.

Antique or Hand-Painted Dishes

  • Why Not: Antique or hand-painted dishes can be easily damaged in the dishwasher. The harsh detergent and high heat can cause the paint to fade, chip, or peel, and can even cause the dish to crack.
  • Tip: To protect these valuable items, wash them by hand using a soft sponge and mild detergent, and dry them immediately.

Plastic Items Not Labeled Dishwasher Safe

  • Why Not: Not all plastic items are designed to withstand the high heat of a dishwasher. Items not labeled as dishwasher safe can warp, melt, or leach harmful chemicals when exposed to high temperatures.
  • Tip: Always check the label before placing plastic items in the dishwasher. If in doubt, wash them by hand with warm water and mild soap.

Knowing what not to put in a dishwasher is essential for keeping your kitchen items in good condition and avoiding damage to your appliance. By hand washing delicate, nonstick, and valuable items, you can extend their lifespan and maintain their quality.
