I have a Gaggia Evo and am using Cleancaf to descale the system. I was working from home and decided to clean my machine between meetings. I got tied up and forgot about the machine for a few hours and left cleancaf in it during that time. I flushed the machine with 2 full clean water cycles and disassembled the basic group head compenents and cleaned them (like I normally do). Is leaving the descaler in the machine for that extended period of time going to harm it?
