Pour 2 cups of distilled white vinegar into the water reservoir. Add enough water to fill the reservoir.
Turn the coffee maker on and wait for it to finish brewing about 1 cup of the liquid.
Turn the appliance off and wait for about one hour to allow the vinegar to dissolve the mineral deposits.
Turn the coffee maker back on and allow it to finish brewing the liquid.
Empty the pot of vinegar and water. Fill the water reservoir with only water and run the brew cycle again. Repeat this once more to remove any traces of vinegar.
