Although these units’ sealed motors usually require no maintenance, there are simple steps operators can take to keep blenders running smoothly. Jeffery M. Brightly, owner of JMB Repairs Inc., Lake Worth, Fla., provides insight into caring for commercial blenders.

  • Keep all components clean. Wipe down the unit with soap and water rather than with a hose or pressure washer, which can damage the motor.
  • Routinely check the container for cracks and make sure that blades turn easily with just
    slight resistance.
  • Blenders typically have a service life ranging from 10 to 15 years for heavy-duty models. When these units stop working, it is generally time for a new one.
