Forgetting to turn off your coffeemaker before you leave the house in the mornings or leaving coffeemakers on overnight can have adverse effects on the look of your coffeemaker. Leaving the pot resting on its burner for too long can lead to scorch marks and discoloration at the bottom of your pot. Not only does it look unsightly, but it can also give your routine cup of joe a bad taste.

Method 1

Method 1 of 3:

Using Ice to Clean Your Coffee pot

1
Add salt and ice to your coffee pot. Start by giving your coffee pot a good rinse. Then place ½ cup of salt into the coffee pot. You will need this to help alleviate the discoloration and burnt marks. After that, add two cups of crushed ice, or enough ice to fill the pot halfway.^{[1]

Add water and lemon to the salt and ice mixture.^{[2]

- When adding additional water, it is important that it is cold. Hot water mixed with the ice will cause the pot to crack or shatter.

Swish the solution around in the pot. As you swish and swirl, you will begin to see the burned brown layer lift from the surface. Watch the stain and the water to measure the improvement of the stain and whether or not it’s removing.^{[3]

- When the water becomes too dark for you to see a difference in the stain and/or discoloration, empty the coffee pot and start the process of adding salt, ice, water, and lemon juice to the pot to continue the process.^{[4]

- Continue to swish the mixture in multiple directions. Keep in mind that severe burns will need more time to soak in the solution so be patient and trust the process.^{[5]

Wash the coffee pot as you would normally before use. To avoid making yourself a salty or sour cup of coffee, rinse your pot thoroughly once the discoloration is visibly removed. Once you have dried the coffee pot out with a soft cloth, you are ready to use it again and make a delicious cup of coffee.

Method 2

Method 2 of 3:

Using Vinegar to Clean Your Coffee Pot

1
Remove film or burned stains with vinegar. White vinegar is known for its extra special cleaning properties and is great for stubborn blackened or burnt stains on coffee pots. Fill the pot to the brim with white vinegar. Let it sit overnight to soak.

Soaking the pot in soapy water may help as well. Bridgett Price of Maid Easy says: "I've seen coffee makers that haven't been cleaned in months, but if you fill them with hot water and a little liquid dish soap, and let it sit for a while, you can actually see the burnt coffee lifting away from the glass. Then, you just have to wipe them out."
2
Pour the vinegar into a large bowl. Place that bowl to the side for later, and wash the coffee pot out with hot soapy water. The majority of the brown stains the coffee pot accrued should be gone completely.^{[6]

Soak the pot again if stains are still evident. Fill the coffee pot with the saved vinegar and allow it to soak overnight. Keep repeating the previous step until all of the stubborn stains have been removed and the coffee pot looks like new again. ^{[7]

Using Baking Soda to Clean Your Coffee Pot

1
Use baking soda and water to clean your coffee pot. Pour one cup of baking soda into the pot and completely fill it with water. Turn on the coffee maker to heat both the water and baking soda in the pot to a rolling boil.^{[8]

2
Begin cleaning your coffee pot. Remove the coffee pot from the heat. Allow the mixture to settle and stand for about 10 minutes. After it’s cooled down a bit, use a soft cloth or non-abrasive scrubbing pads to gently scrub the pot.^{[9]

3
Clean remaining stains by forming a paste in the pot. If there are stains left over even after the baking soda/water boil, take the pot and pour almost all of the mixture out of it. Add more baking soda to the pot to create a paste. Scrub the pot out with the paste. Wash it out thoroughly when the pot is stainless to prepare it for use.^{[10]

Soak the pan in warm water and dishwashing liquid. Then srub it with a scrubby sponge. You may have to use a brillo pad if it is hard to remove the burnt-on food.

Do not use cleanser, although it seems faster. Coffee pots often have lips that could hide residue from the cleanser even when it is rinsed. That residue can end up in your coffee.
