Any coffee machine starts to get an unpleasant smell inside, specifically after long use. The simple, clean and efficient way to get rid of the unpleasant smell and brown coffee stains is … vinegar. Here’s how:
All you need is white vinegar or apple cider vinegar! The first step in cleaning the coffee machine is to empty it, then throw away the coffee grounds and the coffee filter. Rinse the tank with cold water then fill it with 1 part vinegar and 2 parts water.
Pour the liquid in the coffee machine tank, place the jug in its place and start the machine. Once the cycle is completed, stop the machine and wait 15 minutes. Fill the reservoir with water, let it boil and drop the water inside the tank.
Finally, wash all coffee machine parts with warm water and a cleaning solution.
