How Dishwashers Can Damage Your Pots and Pans

How Dishwashers Can Damage Your Pots and Pans

While dishwashers can be a convenient way to clean dishes, they may not be suitable for all types of cookware. If you've ever noticed scratches, discoloration, warping, or rust on your pots and pans after running them through the dishwasher, you're not alone. In this blog, we'll explore the ways that dishwashers can potentially damage your cookware and provide some tips on how to protect your pots and pans from harm.


Scratches One of the most common ways that dishwashers can damage your cookware is through scratches. The high-pressure water jets and strong detergents used in dishwashers can scratch the surface of your pots and pans, especially those made of nonstick or coated materials. Over time, these scratches can compromise the nonstick coating or scratch off the enamel, leaving the underlying metal exposed. To avoid scratches, it's recommended to check the manufacturer's instructions for your cookware and see if they are dishwasher-safe. If not, it's best to wash them by hand with a gentle detergent and warm water.


Corrosion Some types of cookware, such as cast iron or copper, can be prone to corrosion if they are washed in a dishwasher. The high temperatures, harsh detergents, and moisture in the dishwasher can cause the metal to oxidize and rust, leading to discoloration and deterioration of the cookware. Rust can also weaken the metal, causing handles to fall off or pans to become unusable. To protect your cookware from corrosion, it's best to avoid putting them in the dishwasher altogether. Instead, wash them by hand with a mild soap and warm water, and be sure to dry them thoroughly to prevent moisture from accumulating.


Warping Dishwashers use hot water to clean dishes, and some types of cookware may not be able to withstand the high temperatures. Pots and pans made of thin materials, such as aluminum or stainless steel, can warp or buckle in the dishwasher, leading to uneven cooking and potential damage to the stovetop. To prevent warping, it's important to check the manufacturer's instructions for your cookware and see if they are dishwasher-safe. If not, it's best to wash them by hand with a gentle detergent and warm water.


Loss of Shine Some cookware, such as copper or silver, may lose their shine or luster if they are washed in the dishwasher. The detergents and hot water can cause discoloration or tarnishing of the metal, making the cookware appear dull and worn. To preserve the shine of your cookware, it's best to wash them by hand with a mild soap and warm water. If you need to remove stubborn stains or discoloration, use a gentle metal cleaner or polish to restore their shine.


Stripping of Coatings If your pots and pans have a Teflon or other non-stick coating, running them through the dishwasher can strip the coating away, making them less effective at preventing food from sticking to the surface. To protect your non-stick cookware, it's best to wash them by hand with a gentle detergent and warm water, and avoid using abrasive sponges or scrubbers.


In conclusion, while dishwashers can be a convenient way to clean dishes, they may not be suitable for all types of cookware.

To protect your pots and pans from scratches, corrosion, warping, rust, and loss of shine or coatings, it's best to check the manufacturer's instructions for your cookware and see if they are dishwasher-safe. If not, it's best to wash them by hand.
