90% of people have been cleaning their coffee makers wrong! They have the just of it but it’s just not quite accurate.
Here’s the skinny on how to do it correctly.
Fill the whole water chamber up with equal parts white vinegar and water. Turn the coffee maker on and let it run 1/2 way through the cycle then flip it off and let it sit for 1 hour. After the hour is up, turn the maker back on and let it finish. After this step run a few cycles of water through the coffee maker to flush it out.
