How to clean semi-automatic espresso machine maintenance course

Different coffee machines have different time limits, and the life of the espresso machine is about 8 to 10 years. When you carefully clean and maintain it daily, no matter how busy your coffee shop is every day, it will make a good espresso for you.

Highlight: it's too important to effectively clean your coffee maker!

1. Clean in time

Timely cleaning is a good habit for a barista or coffee practitioner.

◎ remembers to clean the steam outlet after milking. To be exact, remember to clean the milk before and after it is disposed of. This will prevent milk from sticking to the steam outlet and blocking the release of steam, as well as preventing the growth of bacteria.

◎ washes the brewing head of the coffee machine with water. If it is not cleaned in time, the oil of the coffee powder will adhere to the brewing head, giving the extracted coffee a strange oil smell. Look down to see if there is coffee grounds around the head, and remember to wash it off together, because the coffee powder adhered to it will not only produce a bad smell, but also hurt the metal of the head.

◎, make sure your cleaning cloth is kept clean. Clean or replace at least 2 or 3 times a day and dry at high temperature after cleaning with detergent.
