Why you should never put milk in the Keurig machine

Keurig machines, as described earlier, are the most conventional coffee machines to brew a single perfect cup of coffee. Keurig coffee makers now come with built-in chocolate pods, so it seems like a good idea to add milk instead of water to the Keurig reservoir; if you think so, you are completely wrong.

Keurig machines are specifically designed to heat Water and only Water. The internal mechanism of Keurig is specifically designed to route Water from reservoir to pod (That is nearly impossible to clean).

Even after rinsing machines or running cleaning cycles, some drops of milk remain in the line or dispensing needle. Once the line is clogged, you will leave behind with few options to unclog it, and most probably, there are chances that you have to buy new coffee machines. Therefore it is greatly advisable to opt for a different method to prepare your milk.

  You can use Keurig Rivo, which comes with a built-in milk frother that facilities you to use milk to prepare your favorite milk-based drinks.

What Will Happen If You Put Milk in Your Keurig

If you add milk to a Keurig machine, you will encounter at least one of these three issues.

1)Burning of milk

The heating element in Keurig is specifically designed to bring water temperature to boiling point in less than a minute. When you use milk instead of water, rapid heating will burn your milk, giving you a sour or bitter drink. Another indication of burning milk is the sharp or strong odor you smell after using milk in the Keurig machine.

2)Spoiling of milk

The Keurig coffee machine is very handy in water storage in the reservoir, which is used to brew your coffee. However, coffee experts recommend not using water standing for twelve hours or more in the reservoir since bacteria can form. Using water standing in the reservoir for 4-5 hours isn’t a bad idea.

However, the same principle can’t be applied to milk. The reason is milk spoils quickly at room temperature, and if you leave it in the warm confines of a Keurig water tank, it won’t be long before it curdles. 

So if you want to make a hot chocolate or milk drink, you’ll need to add fresh, cold milk straight from your fridge to whatever heating tool you use (microwave, a saucepan, or any other). But remember, don’t put milk in a Keurig water reservoir, either for immediate use or later.

It is very difficult to remove milk from the Keurig reservoir. Even if, by miracle, your milk doesn’t get burnt, its residue will spoil and curdle, leaving behind a sour smell that is very difficult to get rid of. 

3)Scorched Metal

Burnt milk will turn into curd and stick to the heating element of Keurig. It will scorch the heating element and prevent the heating element from working effectively.

Internal parts of Keurig have limited access for cleaning, and this buildup of hard milk crust is somehow very difficult to remove. You can make use of a spoon or a scraper to remove this crust buildup, but it is quite tricky, and you may end up damage to internal components. Therefore it is advisable to seek professional help.

How to clean the Keurig machine after adding milk?

So now you think that your machine is out of commission and is garbage now. Fortunately, your machine is still alive, and it is possible to clean it; although it is a bit difficult and requires a lot of time and effort, it gives your machine a new life!

Follow these steps to clean your Keurig machine!

Most Keurig models are specifically designed to allow water to pass through. The internal pipeline that routes water from the reservoir to pods can easily be clogged. Components, especially filters, can easily be clogged by small particles worse than all milk.

You may get into trouble if you add milk into the Keurig machine, even if your machine has a warranty. According to Keurig company policy, a Warranty will not apply to this scenario.

  • First, remember to turn off your Keurig machine because you don’t want any electrical shock while cleaning the machine. 
  • Fetch your specific Keurig model manual and, using screwdrivers, disassemble your Keurig machine.
  •  You can use a scouring sponge to scrape off the crusty residue on the bottom. However, be gentle with your care as you don’t want to damage any components. 
  • Boil water in a kettle and add about half a glass of vinegar. You can also use Alkaline-based froth cleaner and run it through the water lines to ensure that no residue will be left behind.
  • Put the solution in the Keurig water tank and leave it for a while. Hopefully, if there is a milk crust left in the tank, it will come off due to the vinegar. You can also make use of the scrubber to remove it.

For machines with a removable filter, the most common way to clean the inside of your Keurig is with white vinegar. Fill up the reservoir with a 50:50 solution of white vinegar and water, and run the mixture through the reservoir to dissolve and clean out any residue and particles in the system. 

  • Keurig machines, unfortunately, don’t have a drain plug but do have an internal tube that you can take apart and allow the liquid inside to drain out and, in doing so, drain any milk buildup in the line of water.
  • Once all the solids have been removed, you can reassemble the machine and run several cleaning cycles. Fill the water reservoir with a vinegar solution, then run a cycle without inserting a K-cup pod
  • One cycle may not be enough to clean the sticky milk and sour smell from the internal system, so you may need to repeat this process several times until the water runs clear and the smell is completely dissipated.
  •  Rinse the machine with a few cleaning cycles with just filtered water to remove the vinegar.
