The Cleaning Process of the Bunn Coffee Maker Using Vinegar

But you have to first start by assembling all your tools and making them readily available. It is also advisable to sanitizer the area you need to wash the Bunn coffee maker with a pure cloth and anti-bacterial to make it germ-free. After that, follow the steps outline below:

  • Pour one quart of white vinegar into a measuring jug. Then, assemble the coffee machine as normal. Just twist and lock your coffee jug into place and then place the empty carafe onto the base plate. Open the lid and pour the vinegar into the reservoir. Then close the lid and turn on the machine. To get the perfect result, use at least a 20% white vinegar concentrate or stronger.
  • At this point, sit back and let the vinegar do its work. White vinegar is always preferable in this process because it penetrates the hot water tank, effectively eroding any mineral deposits that have built up inside the machine. Note that the cleaning process should take around two hours.
  • After two hours, unplug the brewer and remove the brew funnel. Reach underneath the top of the machine and twist the spray head off in a clockwise direction.
  • At this point, pour a full carafe of distilled water into the top of the machine and close the lid. This water will start to flush the vinegar out from within the hot water tank. However, always ensure to put the carafe on the base plate to catch the water/vinegar solution, otherwise you will be getting everywhere wet! Do this at least ten times until the vinegar smell subsides.
  • Then remove the brew funnel and reinstall the spray head by twisting it into place in a counter clockwise direction. After you must have done this, replace the brew funnel and plug the machine back in so that the water in the hot water tank can heat back up. Add some distilled water to the machine and put your carafe back on the warmer plate.
