Cleaning powder is extremely important when you take care of your espresso machine. You cannot do without it, regardless of whether you have a portafilter or a fully automatic machine. Coffee oil separates during the brewing process. It looks like greasy oil and has a negative effect on the taste of your coffee and at some point the portafilter and brewing unit will turn black because the fat has burned in due to the high temperatures. While the powder is used in tablet form in fully automatic machines, the loose powder is the first choice for portafilter.
