Cleaning Your Coffeepot.
Make it a monthly habit to fill the reservoir of your coffee maker with water and 2-3 tablespoons of white vinegar. Let set in the reservoir for a bit. Then place a filter in the coffee basket and run the mixture through the coffee maker. Then run a pot of plain water through it to remove any taste of the vinegar.
Your coffee will continue to taste like coffee, and you will have cleaned out any bacteria that formed in your coffee maker.
