It may get nicked or twisted. Even minor collisions between the sharp edges and more complex surfaces can lead to injury.

Poor washing

Putting the food processor pieces in the dishwasher is not a wise decision. Hot temperatures, harsh spray nozzles, and chemically aggressive cleansers can cause the blades to deteriorate their sharpness.

Dishwashers are only suitable for cleaning objects that are more robust and do not possess sensitive areas. Remember that the food processor blade has lots of tiny cutting edges that twist and erode fast.

Use caution while using aggressive hand washing chemicals or scrubbing pads, as well. While we often use them to clean pans and pots, they aren’t suitable for processor blades.

Usage techniques

Wash the blades properly

In addition to correctly maintaining the food processor blades, proper cleaning can also help the blade last longer. 

As stated previously, abrasives tear down the blade edges.

After you’ve washed the foodstuff off the blades, remember to dry them well. Then, gently cover the blade’s sharp edges by laying the blade on a towel to let any leftover water drain.
