Owners of coffee pod machines could be drinking more than a delicious caffeinated beverage each time they serve up a cup.
Potentially harmful bacteria might be on the menu alongside some potent mould if people aren’t regularly emptying and cleaning their machines, kitchen appliance cleaning specialists say.
One risk factor is re-using stagnant water that has sat inside the machine in between uses, adding to any nasties already stuck to the inside of unsterilised inner pipes, Sydney-based cleaning company Mr Meticulous owner Marc Hamilton said.
“I don’t think people are consciously choosing to clean them until they break or clog up, then they’re forced to find out what’s wrong and why the liquid isn’t coming through,” he told Yahoo News Australia.
“Because the coffee grounds get harder and harder, it’s like veins in a body, and things just get blocked.”
To avoid creating such issues, people should be running a chemical wash through their machine at least once a month, and ideally flushing their machine out with water after every use.
“After you make your coffee, you press the button again, and it pushes hot water through it, and that will clean it,” Mr Hamilton said.
“If you were to do that, your machine would stay relatively clean. But no one does.”
‘Water is the problem.’
Mr Hamilton said he thought it was unlikely coffee from a dirty machine would cause any health issues, but the same might not be able to be said for the water.
“The water in the pipes and reservoirs, if that’s not cleaned or flushed, there will be bacteria in that. Because it gets heated and then cools down,” Marc said.
“Things can get mouldy so quickly.”
He thought it was more common for people to purchase a new coffee machine for their home if their machine suddenly broke.
“They’re all so new, and when they break down, you can go and get a new one. Coffee Machines don’t cost much; it’s a no-brainer,” Mr Hamilton said.
How often should you clean your machine?
Yahoo News Australia suggests owners of coffee pod machines were not cleaning their appliances anywhere close to enough.
“I would advise people to clean it every day. After every use, they should wipe it off and if they’re worried about deep cleaning, once a week is the best option,” marc hamilton.
