Can you put chef knives in the dishwasher?
It is commonly advised that you should not put your chef’s knife in the dishwasher to clean it. This is because good knives can often be expensive and need to be regularly maintained, which can be difficult if done manually.
Putting a chef’s knife in the dishwasher can quickly ruin it, in part due to the harsh chemicals, the extended exposure to water, and the potential to scrape on other utensils and surfaces.
Why do knives rust in the dishwasher?
It is a common misconception that knives are dishwasher safe. However, most knives are made of steel, which is susceptible to rusting.
When knives are placed in the dishwasher, they are submerged in water and exposed to detergent, which can cause corrosion.
Over time, this can lead to dullness or rustiness.
To prevent this from happening, it is best to wash knives by hand.
Does washing a knife in the dishwasher make it dull?
Dishwashers can damage a knife’s sharpness. The high temperatures and harsh detergents can break down the blade’s steel, making it less effective.

Washing a knife in the dishwasher can make it duller than if it was hand-washed.
However, this doesn’t mean that you should never wash your knives in the dishwasher.
If you do choose to wash them in the dishwasher, be sure to use a low heat setting and avoid using harsh detergents.

How does the dishwasher dull knives?
The dishwashers are great. They wash nearly anything and they make our lives so much simpler. They can be dangerous for knives, however.
They can dull the blade of the knife if a few ways.
First, if the knife is placed in the utensil basket tip down this does increase the chances that the blade tip can break off and can get damaged.
Another issue is that a dishwasher moves the knives around.
If you place more than one in the same basket they can knock into one another and can then dull and become damaged as well.
The last issue is that some knives are simply not meant for very high heat and the high heat of the dishwasher can damage the blades.
Detergent chemicals that may ruin the knife
Dishwasher detergent can contain enzymes that help break down protein, fats, and starches.
The chemicals in dishwasher detergent can also be tough on knives and potentially cause corrosion.
And if exposed to it long enough, the detergent chemicals will dull the knife or even damage the steel. A dull knife isn’t as effective and can be dangerous to use.
To avoid this issue, it is best to hand wash your knives with mild soap and water after each use. This will remove any build-up of detergent chemicals and help keep your knives sharp and in good condition.
If you rather use a dishwasher to wash your dirty dishes and knives, then consider using less or milder detergent.
Heat and water pressure
Knives are made of metal, and exposure to hot water can cause the metal to warp or even break.
Additionally, the turbulence caused by the pressure and movement of water can damage knives.
For these reasons, it’s best to hand-wash knives rather than run them through the dishwasher.
