Did you know that your coffee capsule pod machine leaves coffee residue and oil behind each time you make a coffee? Coffee capsule and coffee pod machines can turn into real bacteria hot spots when left uncleaned. Descaling alone does not help. You need to get into the coffee capsule machine’s brewing chamber. If the spout, nozzle and brew unit of your machine is dirty, your coffee will taste poorly. And you can also expect blockages and slow coffee flow in your coffee capsule machine.
