What Are Algae?

The CDC indicates that algae are simple, have the same features as plants, and reside in water. If algae are not controlled, they can bloom beyond control. 

Dangerous algae, also called blue-green algae, can release toxic substances that will likely cause illness to you, your loved ones, and even your pets.

  • Pour the Keurig descaling solution and water in equal measures into the Keurig water reservoir.
  • Make a cup of hot water and do the process for 5-10 seconds each time until the mixture is removed from the coffee maker.
  • When your coffee maker indicates that you should add water, allow it to rest for about 30 minutes for the mixture to disinfect the algae still in the equipment.
  • Clean other parts of the coffee maker with the mixture, such as the mesh screen and filter holder, 
  • Clean the water tank exhaustively and then fill it with clean water.
  • Fix your coffee maker and make several cups of hot water to remove any remaining mixture from the equipment.

Cleaning Using White Vinegar or Baking Soda

Coffee makers, including Keurigs, can get blocked by the accumulation of hard water. This build-up causes poor performance.

The proper way to remove the blockage from the Keurig water reservoir is to use white vinegar or baking soda; a method termed descaling. 

Vinegar and baking soda are just as effective as other commercial cleaning solutions. For a squeaky spotless coffee maker, follow this process:

  • If the manufacturer indicates the water reservoir should not be cleaned in the dishwasher, use the same blend of white vinegar and water. Otherwise, you can pour water and a quarter cup of baking soda. Then with a round-tipped brush, clean the inner section. This move will scrub the reservoir and water opening section.
  • Also, remove the k-cup and pour the mixture into the coffee maker. If you have stayed without cleaning your coffee maker for an extended period, you should repeat this technique several times.
  • After pouring the mixture a few times through your equipment, run clean water at least three or four times to remove the baking soda or vinegar.
  • If your coffee maker has a bigger reservoir that is permanently occupied, it is vital to empty it and pour clean water numerous times. 

How to Care for Your Coffee Maker

If you want your Keurig to serve you for many years, you must have a routine cleaning procedure. Here are some of the things you can do to make sure you do not go back to the shop for another coffee machine soon:

  • Allow the Keurig Water Reservoir to Dry by Leaving it Open

If you have small or single-serving coffee equipment, it is best to leave it open after making your coffee. This helps the water tank to dry.

If the water tank remains wet for an extended period, algae will likely bloom in such an environment making your coffee taste awful the next time you brew.

  • Ensure Your Coffee Maker is Dry after Brewing Coffee

Take a paper towel and dry the interior of your coffee maker after making your coffee. There are fewer chances that algae will bloom in a dry place.

  • Wash the Platform Tray for the Cups

Extra water and coffee go into this tray, creating slime. If you make coffee regularly, your tray probably has stagnant water and algae.

Take a kitchen towel and use soap and water to clean it.

  • Buy Bottled Water

Instead of using tap water to make coffee, use bottled water. Bottled water contains minimal minerals compared to tap water and is likely to have less blockage in your Keurig coffee maker. Nonetheless, bottled water is costly.

Alternatively use a water filter to eliminate most of the minerals in your tap water.

  • Only Use Clean Cups

Avoid dirty cups as they are likely to host algae and other dangerous microorganisms that can alter the taste of your coffee and affect your health.
