Everyone has an opinion about which method is best for cleaning coffee carafes. Some methods work better for glass carafes and some are best for thermal carafes; most work well on both types of carafes. This article will look at different ways to remove the residue, oils, grounds, mineral deposits and other coffee-related substances that build up in and on coffee carafes. Buying special products to clean either a glass or a thermal coffee carafe is seldom necessary. The simplest methods for cleaning carafes use household products that most people have in their homes.
Rinse the carafe and then fill it with warm water. This should be done after every pot of coffee.
Squeeze some of your favorite grease-cutting liquid dish soap.
Soak the carafe filled with soap and water for a few minutes while you wipe off the coffee maker itself.
Wash the inside and outside of the carafe with a sponge or soft cloth. Don't forget to wash the bottom of the carafe and the carafe's lid if there is one.
Rinse well, then rinse again, so your next cup of coffee will not taste like soap.
Air dry the carafe to avoid towel lint sticking to the inside and showing up in your morning coffee.
Fill the coffee carafe with water and one-third of a cup of white vinegar. This method lets you clean both the carafe and the coffee maker at the same time.
Pour the vinegar and water solution into your coffee maker, and turn the machine on as if you were brewing coffee. This will allow the vinegar and water solution to drip into the carafe.
After the coffee-making cycle is complete and the vinegar water has filled the carafe, let it soak for about fifteen minutes.
Discard the vinegar solution and rinse the carafe.
Pour plain water into the coffee maker and run the machine through two more cycles to be sure you get rid of any vinegar flavor.
Fill the carafe with warm water plus a teaspoon of baking soda and let that soak for a few minutes before thoroughly rinsing the carafe. This will get rid of the taste and smell of vinegar.
Air dry the carafe.
Squeeze a lemon or pour lemon juice into the carafe. This method calls for lemons or lemon juice, kosher salt, and ice cubes or, even better, crushed ice.
Add two to three tablespoons of coarse or Kosher salt.
Put a handful or two of ice cubes or crushed ice into the carafe.
Swirl the the combination of ice, salt, and lemon in the carafe. This vigorous action works with the lemon, ice and abrasive salt to scrub away even the most stubborn coffee stains.
Rinse the carafe with warm water. Boiling hot water is fine for rinsing or soaking a thermal carafe, but hot water is not advisable for rinsing a glass carafe. Using cool or tepid water to rinse the glass carafe is safer, especially after the lemon, salt, and ice cleansing.
Air dry the carafe.
Fill the carafe with warm water.
Drop one or two anti-bacterial denture cleaning tablets into your carafe and allow the solution to soak for fifteen minutes. Denture cleaning tablets or even a product like Alka Seltzer can provide one of the quickest methods for cleaning a carafe.
Scrub the inside of the carafe with a dish brush or, if this is a thermal carafe with a narrow opening, use a bottle brush. The denture tablet method is especially effective when you are trying to clean a carafe that has a narrow opening because the denture solution erodes the coffee residue you are unable to see.
Wash the inside and outside of the carafe with warm water and a little soap.
Rinse well to remove any soap remaining in the carafe.
Air dry the carafe.
Coffee carafes really do need to be cleaned on a regular basis. You will be delighted by how much more delicious your coffee tastes when it is brewed in and served from a thoroughly clean carafe.
Carafes are not easy to replace, especially if you have an older coffee maker, and, because they are not usually interchangeable. If your glass carafe breaks, you will have to buy a replacement from the manufacturer. Purchasing a new carafe and having it shipped can be expensive. Consider buying a thermal carafe next time. Thermal carafes or stainless steel carafes are more durable and can't shatter when dropped, bumped, or handled imperfectly. However, thermal coffee carafes are a little more difficult to clean, are not dishwasher-safe, and they might require special cleaners.
Glass carafes are fragile, so, whichever cleaning method you choose, be very careful not to break the carafe. The glass is thin, and, when broken, can create very sharp shards that may cause deep cuts, especially if the carafe breaks while you are washing it.
