How do you clean a commercial coffee machine?


Whether you’re running a coffee shop or a restaurant or a bar, it is very important to keep all the coffee equipment clean. No matter if you buy high-quality beans, you won’t get the taste unless you clean the coffee machine.

Not cleaning your coffee machine regularly will not only produce sticky coffee but will shorten the life of seals and filters too. While your coffee maker should have a manual with cleaning instructions, do the following if you don’t have one:

  • Weekly routine:
  1. Place a tablespoon of backflush detergent in a “blind filter” on a group handle
  2. Lock the group handle on the coffee maker. Once locked, start flushing. Most espresso machine detergents recommend four start/stop intervals of 15 seconds. However, follow the instructions provided with the cleaning agent you’re using
  3. After washing with detergent, repeat the process with clean water until you are sure it is completely rinsed. It is recommended to rinse the same amount as the detergent phase
  4. A cleaning brush removes stubborn coffee grease. Do not allow leave plastic parts in detergent water as detergent may end up discoloring the parts
  5. Remove the nozzle from the tip of the steam nozzle. Take a clean cloth, damp it with hot water and clean your steam wand. Remove the burned milk from the baguette. Use a steam brush to clean the inside of the steam wand. The pressure of steam can be affected if clogged with dry milk residue
  6. Your bean container should also be cleaned. Backflush detergent and warm water is enough to clean it, but then rinse them thoroughly
  • Daily routine:
  1. Take a small plastic bucket and fill it with warm water. Pour into a commercial espresso machine cleaner and prepare the solution. You’re going to use it to soak parts overnight.
  2. Rinse the group heads with fresh water. Place the blanking plates on the group heads and run the head under cold water for about 10 seconds. Release the pressure and repeat the process until the water is completely clean.
  3. Clean the filter basket in warm water with a sponge and soap. Then place the filter basket in the solution bucket.
  4. Clean the basket-end of group handle with a scrubbing pad with running warm water. Put the basket-end to the solution bucket for overnight soaking. It is best not to soak plastic parts in detergents if they are colored.
  5. Clean the shower-heads. Clean the drip tray and gratings and let them dry overnight.
  6. Clean the steam nozzle with a soft cloth after pouring a single coffee. At the end of each day, remove and disinfect the tip of the steam wand.
  7. Clean the outside of the espresso machine to remove dirt from the surface. For dirt or grease stains, apply a little baking soda to water and vinegar and scrub the area with a non-abrasive sponge or a soft- bristle brush.
