Cleaning a commercial coffee machine is important for maintaining its performance, flavour quality, and longevity. Here is a basic cleaning routine that you can follow to keep your commercial coffee machine in good condition:

1. Daily cleaning: After each use, it’s important to wipe down the machine’s exterior and any removable parts, such as the portafilter, with a damp cloth. Empty any residual water from the drip tray and rinse it with hot water.

2. Weekly cleaning: Every week, it’s a good idea to run a cleaning solution through the machine to remove any buildup of coffee oils and residues. You can purchase commercial espresso machine cleaner, or make your own by mixing equal parts water and vinegar. Fill the machine’s water reservoir with the cleaning solution and run it through the machine just like you would with water.

3. Monthly cleaning: Once a month, it’s a good idea to thoroughly clean the machine’s group head, shower screen, and any other parts that come into contact with coffee. Use a soft brush to scrub these parts and a cleaning solution to remove any buildup.

4. Decalcification: It’s also important to regularly decalcify the machine to remove any mineral buildup that can affect the machine’s performance and flavor quality. You can purchase commercial decalcifiers, or use a solution of equal parts water and vinegar. Fill the machine’s water reservoir with the decalcification solution and run it through the machine just like you would with water.

Note: Always refer to the manufacturer’s instructions for specific cleaning and maintenance guidelines for your commercial coffee machine, as the cleaning process can vary depending on the model and manufacturer.
