7 potential risks of washing stainless steel kitchenware in the dishwasher

1. Scratching and surface damage

Dishwashers use high-pressure jets to clean dishes, which can cause tiny particles like food residues or other hard objects to be propelled against the stainless steel surface.

Over time, this can result in scratches and abrasions, detracting from the cookware’s aesthetic appeal and making cleaning more challenging.

2. Discoloration and stains

Some dishwasher detergents contain harsh chemicals and high alkaline levels, which may react with the stainless steel, leading to discoloration and the appearance of stains on the cookware. This can create an uneven or patchy surface, affecting the cookware’s overall look.

3. Pitting and corrosion

Stainless steel is designed to resist corrosion, but extended exposure to harsh dishwasher environments can lead to pitting (tiny holes) in the cookware’s surface.

This can compromise the integrity of the material and may eventually lead to rust formation.

4. Damage to non-stick coatings

Many stainless steel pans have non-stick coatings applied to the cooking surface. The dishwasher’s aggressive cleaning process can wear down or damage these coatings, reducing their effectiveness and making them less nonstick over time.

5. Warping and structural damage

The extreme heat during dishwasher cycles can cause uneven expansion and contraction of the metal, leading to warping or deformation of the cookware.

This can affect the flatness of the cooking surface and, in extreme cases, impair its ability to sit properly on a stove burner.

6. Weakening of handles and rivets

Stainless steel cookware typically has handles and rivets made from different materials, such as plastic or wood.

Continuous exposure to high temperatures and water in the dishwasher can weaken the bonds between the metal and non-metal components, leading to the loosening of handles or even detachment.

7. Leaching of Harmful Materials

In some cases, lower-quality stainless steel or poorly manufactured cookware may contain small amounts of other metals like nickel, which can leach into the food when exposed to harsh dishwasher conditions.

Although stainless steel is generally considered safe for cooking, extended exposure to such conditions might lead to increased metal leaching.
