love-coffeeFor fresh tasting coffee with a smell that’s certain to wake you up in the morning, it’s important to clean your coffee maker once a week. This prevents lime, hard water deposits and grime from building up on the inside and in the brew basket.


  • 1 Jug Of White Vinegar
  • Water
  • Spray Bottle
  • Paper Towels
  • Dishwasher or Dish Brush And Dish Soap


Cleaning The Inside

Empty and rinse out the glass carafe. If the coffee maker makes 12 cups, pour six cups of vinegar into the carafe. Then, fill the remainder of the pot with water. If it makes less than 12 cups, simply ensure that the ratio of vinegar to water is 50/50.

Put an empty filter into the basket and turn on the machine as if you were brewing coffee. Let it brew about half the mixture before turning it off and letting it sit for 60 minutes. During this time the vinegar will dissolve any hard water and lime deposits, and it will loosen grime and stains in the basket and on the carafe.

After 60 minutes, turn it back on to process the rest of the mixture. Dump the carafe into the sink and rinse the remaining vinegar and water by running two more cycles of plain water through. It is thoroughly rinsed when the smell of vinegar is no longer noticeable.

To prevent the pot from breaking during the rinse cycles, it’s important to either let it cool completely or fill the pot with very hot water. A rapid change in water temperature can cause glass pots to crack.

Cleaning The Carafe And Basket

The easiest way to clean the carafe and basket is to put them in the dishwasher and wash them with your regular load of dishes. The spray of hot water from the machine will effectively remove residual grounds and grime and sterilize the basket and pot.

If you do not have a dishwasher, they can be cleaned using a dish brush that has bristles all the way around the end of the brush and dish soap. Squirt a little dish soap in and add hot water to create suds. Use the brush to scrub the sides and bottom and between the narrow flow guides of the basket. Rinse thoroughly and place in a dish drainer to dry.

Wash the pot as you would any other dish, rinse thoroughly and allow to air dry.

Cleaning The Outside

Create a mixture of 50 percent water and 50 percent vinegar inside your spray bottle. Spray the outside of the brewer, inside of the brew basket holder and the warming plate liberally with the solution. Allow it to sit for 10 minutes. Wipe away the mixture, grime and grounds with paper towels. There is no need to rinse, it is now clean and ready for use.
