Using a dishwasher can save you time and effort in the kitchen, but not everything is safe to toss in there. Certain items can get damaged or even harm your dishwasher if washed inappropriately.
Knowing which things you should never put in the dishwasher helps protect your kitchenware and keeps your appliance running smoothly. This article will guide you through five common items to avoid putting in your dishwasher to keep everything in the best shape.
Cast iron pans
You should never put cast iron pans in the dishwasher. The harsh detergent and high water temperature strip away the seasoning that protects your pan.
When the seasoning comes off, your pan becomes prone to rust and food sticks more easily. Instead, wash it by hand with hot water and a stiff brush.
After cleaning, dry your pan thoroughly and apply a light coat of oil. This helps maintain its nonstick surface and extends the life of your cast iron.
Wooden spoons
You should avoid putting wooden spoons in the dishwasher. The heat and water can cause the wood to warp, crack, or splinter over time.
Dishwasher detergent can strip away the natural oils in the wood, making your spoons dry and prone to damage. This also creates small cracks where bacteria can hide.
Instead, wash your wooden spoons by hand with mild soap and warm water. Dry them thoroughly with a towel and let them air dry. This will help keep them strong and safe for cooking.
Sharp kitchen knives
You should never put sharp kitchen knives in the dishwasher. The high heat and strong water jets can dull the blade quickly.
Knives can also bump against other items, causing nicks or damage to both the blade and your dishwasher racks. This can lead to rust or dull spots.
Washing your knives by hand with mild soap and drying them immediately helps keep the edge sharp and extends their life. It’s safer for you and better for your knives.
Non-stick cookware
You might see some non-stick pans labeled dishwasher-safe, but it’s best to hand wash them. The hot water and strong detergents in dishwashers can wear down the non-stick coating over time.
When that coating starts to break, your pan loses its effectiveness and may even flake, which you don’t want in your food. Using a soft sponge and gentle soap will help your non-stick cookware last longer.
If you do use the dishwasher, put non-stick items on the top rack to reduce damage. But hand washing remains the safest way to keep your pans in good shape.
Crystal glassware
You should avoid putting crystal glassware in the dishwasher. The high heat and strong water jets can cause your crystal to chip or crack.
Over time, the heat may also cause your crystal to look cloudy or etched. This dulls the sparkle that makes crystal special.
To keep your crystal looking its best, wash it gently by hand using warm water and mild soap. Dry it with a soft towel to prevent water spots and preserve its shine.
