How To Clean An Espresso Machine?
Sep 25, 2025| Why is it necessary to clean the espresso machine regularly?
Espresso machines accumulate coffee grounds, grease and scale during daily use. If not cleaned in time, it will not only affect the flavor of coffee, but also may clog the machine, leading to a decline in performance. Long-term neglect of cleaning the espresso machine may even damage the internal parts and increase the maintenance cost. Therefore, regular maintenance and deep cleaning are the keys to keeping the coffee machine running efficiently.
Steps for daily cleaning of an espresso machine
1. Clean the coffee grounds and the brewing head
After each use, be sure to empty the coffee grounds box and clean the brewing head with a special brush to prevent the remaining coffee grounds from hardening. Meanwhile, wipe the exterior of the machine with a damp cloth to keep it clean.
2. Clean the filter and handle of the espresso machine
Remove the filter screen and handle, and soak them in warm water and neutral detergent to remove the remaining coffee oil. Stubborn stains can be treated with baking soda or a special cleaner, but avoid using hard brushes to prevent scratching the surface.
3. Descaling: Remove accumulated scale
Scale is a common problem affecting the performance of coffee machines, especially in areas where hard water is used. It is recommended to use food-grade scale remover for deep cleaning every 1 to 2 months. Dissolve the descaling agent as per the instructions and inject it into the water tank. Run the cleaning program and finally rinse thoroughly with clean water to avoid chemical residues.
Tips for deeply cleaning an espresso machine
In addition to daily maintenance, a deep cleaning should be carried out every 3 to 6 months, especially for commercial espresso machines. The following are the key steps:
Backflushing: Use a blind filter and special cleaning powder to circulate the cleaning agent inside the machine, thoroughly removing coffee grease from the pipes.
Steam rod cleaning: Steam rods are prone to accumulate milk residue. After use, they should be wiped immediately with a damp cloth and regularly soaked in steam rod cleaner to prevent clogging.
Check the sealing ring and pipelines: If you find that the boiling head is leaking or the pressure is insufficient, it may be that the sealing ring is aged and needs to be replaced in time.
Choose the appropriate cleaning products
There are various types of coffee machine cleaners available on the market. It is recommended to choose food-grade and non-corrosive products to avoid damaging the internal components of the machine. Meanwhile, regularly replacing the water filter (if the machine is equipped) can also reduce the accumulation of scale and improve the quality of coffee.
Mastering how to clean an espresso machine can not only enhance the taste of the coffee but also extend the lifespan of the equipment and save maintenance costs. Whether it is a household or commercial coffee machine, regular maintenance is indispensable.
