The Deep Clean Method
Every once in a while, take a little more time to clean your espresso machine more thoroughly to ensure it continues to run at optimum quality. If your coffee machine is taking longer than usual to brew, or the espresso isn’t extracting a shot the way it should, these may be signs that your espresso machine needs a deep clean.
If you’re wondering how to clean an espresso machine to sparkling perfection, look no further. To deep-clean your espresso machine, you should always use a store-bought espresso cleaning solution.
Note: Consult your espresso machine’s manual to choose the best cleaning solution for your machine. The process will vary for each:
Make sure you remove the water filter as it will soak the descale solution if left in during the descaling process.
Step 1: Mix the Cleaning Solution
Power on your machine and mix the cleaning agent using the instructions on the pack. If using vinegar use 1 part water to 1 part vinegar, then fill the water tank to the max line.
Step 2: Run the Solution Through the Machine
Next, you’re going to run the espresso machine the same way you would if you were brewing an espresso. Except, you’ll run your mixed solution, through the machine. Place a large bowl or container below the portafilter, hot water outlet and steam wand (respectively) to catch the solution as it runs. Be sure to run each respectively on rotation, running the mixed solution through each function of the machine until all of the mixed solution has been used.
Step 3: Run Water Through the Machine
After the first round of cleaning solution has run through the machine, run a second round with only water. This is to flush out the cleaning agent you have used so that the machine is purified before brewing espresso.
Step 4: Inspect and Repeat As Needed
Once this rinse is complete, a second flush is a great idea before you inspect your machine. Look for any remaining coffee residue, mineral buildup, coffee grounds, or oil stains. If stubborn spots are still present, try wiping them down with a clean cloth or run another rinse cycle through the machine.
