Commercial coffee makers run every day in offices, restaurants, coffee shops and diners to keep us caffeinated. They are made to be workhorses and can brew coffee all day long. However, after six to eight hours of constant brewing, commercial coffee makers need to be cleaned in order to continue to brew coffee that doesn't taste particularly oily or burnt. Cleaning these types of coffee makers is best done with a cleaner designed for commercial coffee makers, which keeps the cleaning process to an effective minimum.

Things You'll Need

  • Commercial coffee cleaner approved by your local health department
  • Water
  • Salt
  • Ice
  • Clean towel

Turn off the coffee maker and allow the coffee pots to cool.

Fill the coffee pots 1/3 of the way full with ice and cover the ice with a thin layer of salt. Swirl the salt-ice mixture around in the coffee pots for three to five minutes to loosen any stains. Dump the salt-ice mix and rinse with lukewarm water.

Replace the coffee pots onto the burners and add the commercial coffee cleaner as directed by the manufacturer. Some cleaners require being placed in a filter in the filter holder while others go directly into the coffee pots.

Turn on the commercial coffee maker and run the brew cycle.

Turn off the coffee maker and let the coffee pots sit with the cleaner for ten minutes.

Wet a towel with the cleaning solution. Wring it out so the towel is damp and use it to wipe down the outside of the coffee maker including the still warm (but not hot) burners.

Rinse out the coffee pots thoroughly.
