Home Remedies for Cleaning Coffee Makers

Clean coffee makers make the best tasting coffee, according to the website Coffee Statistics.


Over time, trace deposits left from the coffee and minerals from the water accumulate in the coffee maker and can change the taste of the coffee. Commercial coffee maker cleaning products are available, but many common home products also are effective in removing unwanted materials from the coffee maker. .

White vinegar is probably the most common household product used to clean coffee makers. Mix half vinegar and half water in the water tank of the coffee maker, turn the machine on and allow it to run through the entire coffee-making cycle. Pour out the vinegar mix and run a cycle of clean water before brewing a batch of coffee.

Baking Soda

Mix 1-cup water and 1/4-cup baking soda, and place in the water tank of the coffee maker. Run the coffee maker through its normal cycle. Run three cycles of clear water through the coffee maker to rinse the baking soda mix from the machine.


Pour 1 cup of bleach directly into the carafe or "pot" of the coffee maker. Use a rag, along with a spoon or other implement if necessary, to scrub the interior of the coffee carafe. Rinse thoroughly with clear water before using the coffee pot. Do not run bleach through the entire coffee maker. Use only in the glass carafe.


Mix a 1/2-cup salt with enough crushed ice to fill the carafe or pot. Shake or swirl the pot around to cause the ice and salt to rub against the interior of the carafe. Rinse the carafe with clear water before using the coffee maker. Use the salt only on the carafe rather than the entire coffee maker.

Exterior Cleaning

Clean the exterior of the coffee maker with vinegar or baking soda. Both are effective at cleaning accumulated mineral deposits and brightening the glass. Prepare the mix according to the instructions and wipe the exterior of the coffee maker with a sponge or rag soaked in the mixture. Rinse with clear water. Avoid getting the electrical heating element excessively wet and do not submerge the coffee maker.
