Methods for Removing Tough Stains in Coffee Pots

Quck answer

Hard water stains in coffee pots can be stubborn and unsightly. Fortunately, there are several effective methods to remove them. One option is to fill the pot with equal parts vinegar and water, then let it sit for an hour before scrubbing with a brush. Another method involves adding a tablespoon of baking soda to warm water, allowing it to sit overnight, and then scrubbing the stains away. Alternatively, using a commercial descaler specifically designed for coffee pots can also be effective. Regular cleaning and descaling can help prevent future stains and ensure a clean, great-tasting cup of coffee.


For coffee lovers, the aroma of freshly brewed coffee in the morning is a delightful way to start the day. However, while the coffee pot may be an essential part of your daily routine, it often gets neglected when it comes to cleaning.

To keep your coffee maker functioning at its best, it’s important to give it some care from time to time. Whether it’s residue from coffee grounds or mineral deposits from hard water, various substances can interfere with the machine’s ability to brew the perfect cup of joe.

Fortunately, cleaning a glass coffee pot is not a difficult task with the right cleaning solution.

Using Lemon Juice to Clean a Coffee Machine

Over time, the inside of the coffee pot can develop stains from old coffee that has been left to sit. If a quick rinse doesn’t remove these stains from the bottom and sides of the pot, lemon juice can be used to break down the oily residue.

You can purchase bottled lemon juice or squeeze fresh lemons for this purpose. Mix 1/2 cup of lemon juice with 1/2 cup of water and pour it into the reservoir of the coffee maker. Allow it to sit for about 15 minutes to dissolve the oils and mineral deposits. Then, run a cycle to clean the machine.

If you choose to use fresh lemons, don’t throw away the rinds. Place the rinds and 1 tablespoon of salt in the carafe and run a cycle with plain water. This will ensure a sparkling clean pot. After cleaning, run another cycle with plain water to remove any lingering lemon essence before brewing your morning coffee.

Using Vinegar to Clean a Coffee Maker

Vinegar is an excellent cleaner for removing hard water buildup in a coffee maker’s reservoir and filters. Simply run a few cups of vinegar through the machine to quickly eliminate the deposits. However, be prepared for a strong odor.

Once the hard water deposits have been removed, rinse the carafe with soap and water to ensure that all traces of vinegar are gone. Wipe the hot plate under the carafe and run a water cycle through the coffee maker.

Using a Coffee Pot Cleaner

If you prefer a specific cleaner for your glass coffee pot, a mixture of ice cubes and table salt can be highly effective. This combination helps to break down oils and stains from both glass and metal pots.

Start by placing a layer of salt at the bottom of the carafe and then add enough ice cubes to cover it. Swirl the pot around to ensure that the ice and salt mix well and adhere to the sides. As the ice melts, it will create an abrasive action that gently scrubs the interior of the pot.

If you have accidentally left a small amount of coffee on the burner for an extended period of time, you might find it helpful to incorporate fresh lemons into the mixture. Once the task is finished, make sure to thoroughly rinse the area.
