It won’t be wrong to say that Keurig is the king of coffee machines. However, like all the other coffee machines, Keurigs also develop lime scale over time. Lime scale not only affects the performance of the coffee machine but also affects the taste of the coffee prepared on the machine. Therefore, it is important to descale Keurig 2.0 on a regular basis.
There are a number of ways to descale Keurig 2.0
coffee machine. One of the cheapest and most effective ways of descaling is to use vinegar to clean the coffee machine. However, you can also use lemon juice as well as commercial cleaners for cleaning the inside of the coffee machine
The first thing you need to do is to take out any k-cups from the machine. It is also important to remove the funnel as well as the cup holder though if you want to leave them in, it won’t cause any problems with cleaning. If you leave the cup holder inside, it will help in guiding the cleaning solution or vinegar to the exit spout and prevent any spills.
Next you need to remove the water tank from the coffee machine and throw any water in the reservoir in the sink. Also, remove the water filter inside and set it aside. When you start this possess, it is important that the automatic shut off setting isn’t turned off. The cleaning solution is going to be there in the coffee machine for a long period of time and the brewer will need to be working during this time. Therefore, make sure that this automatic shut off is turned off so that it does not shut off the cleaning process.
For descaling the coffee machine, you will be using distilled white vinegar. So, take some white vinegar and create a solution by mixing it with equal amount of water. It is important to dilute the vinegar as undiluted vinegar may damage the insides of the machine. Also, do not make the mistake of using Apple cider vinegar. One of the biggest disadvantages of using ACV is that it may leave some of the flavor inside the machine and that will affect the flavor of your coffee.
You may use ACV in case you do not have white vinegar but you will need to do several extra rinses to get rid of flavor in the machine. You may also use lemon juice in place of vinegar but you will need a lot of lemon juice. If the scale buildup is not that bad, fill the water tank with lemon juice around a third of the way. However, if there is too much scale buildup, you should fill the water tank at least half the way with lemon juice.
After pouring lemon juice or vinegar in the water tank, pour some water in it but it is important that you fill it up only up to the top fill line. This will dilute the vinegar and make it safe for use in the coffee machine. Now, place a ceramic mug beneath the spout to ensure that there is no overflow or spill. Now, it is time to switch on the machine and brew a cup of hot water in the coffee machine.
When you start brewing hot water, the diluted vinegar will flow through the machine and get rid of any lime scale buildup inside. Keep repeating the process until the water tank is almost empty. Your machine will start flashing lights on the screen but you just need to turn it off.
The cleaning process is still not complete. The remaining vinegar in the water tank needs to stay there for at least four hours. During these four hours, undiluted vinegar will keep working inside the machine. After four hours, take the remaining vinegar in the water tank and pour it into the sink. Make sure that all the vinegar in the tank is completely gone before you move on to the next step in this process.
Even after rinsing the water tank thoroughly, there will be some vinegar left inside the water tank. Therefore, you need to use fresh water to flush out all the vinegar from the coffee machine. In case, you do not flush out all the vinegar, you may get bad tasting coffee due to presence of vinegar.
Once you have thoroughly rinsed the water tank, it is time to brew a cup of hot water. Most likely, you will notice a strong smell of vinegar but this is completely normal. You will need to brew multiple cups of hot water to get rid of the smell. Keep repeating the process until the water tank is completely empty.
You may also use citric acid to descale Keurig 2.0. To descale the coffee machine using citric acid, you’ll need to take one to 2 tablespoons of citric acid per liter of water. Citric acid is easily available in grocery stores. Use a spoon to mix the citric acid in the water. Now you need to put this solution in the water tank. This citric acid will slow chew through all the lime scale buildup inside the machine. Now you need to brew a cup of hot water and let the citric acid solution flow through the coffee machine. It will dissolve all the lime scale buildup inside as it flows through the machine.
Keep repeating this process until the water reservoir is completely empty. Once the water tank is completely empty, refill it with cold water and start brewing cups of hot water. It is important to repeat this step a number of times to make sure that the citric acid inside the machine is completely flushed out.
Instead of using vinegar or citric acid, you may also use cleaning solution made by the company. There are a number of different cleaning solutions available in the market but it is important to make sure that you follow all the recommended proportions for the cleaning solution as given on the label.
In case of Keurig cleaning solution, you need to add equal amount of water to dilute the cleaning solution. You need to fill the water tank with this cleaning solution and keep brewing cups of hot water until the water tank is completely empty. Once there is no more water in the water tank, you need to wait for at least 30 min but make sure that machine stays on. This cleaning solution will keep working inside to get rid of any lime scale buildup.
After 30 min, fill the water tank with cold water and start brewing cups of hot water. Keep repeating this process until there is no cleaning solution left inside the coffee machine.
The descaling process should be repeated every 3 to 6 months. In case, the machine indicates that it needs descaling even after performing the process, you will need to repeat the cleaning and rinsing process. If the water in your area has a high mineral content, you should descale Keurig 2.0 every three months.
