White Vinegar works great for cleaning your coffee maker. Pour one cup of vinegar in your pot and then fill with water and start your pot. Allow the coffee maker to brew and then once finished refill the pot with fresh water and allow the pot the brew again. You next pot of coffee will taste much better without all the water build up in the pot. The vinegar works great to break down the build up from hard water. I also found that soaking the vaporizor parts in vinegar works great for keeping the vaporizor clean too.
