Man Brewing From A Mr. Coffee Espresso Machine

There are two types of cleaning for your coffee maker - regular and deep cleaning.

Regular cleans are done every day or every week, depending on how often you go through those coffee grounds. 

This simple process is quick and ensures you get top-quality coffee every time.

Here are our tips on how to clean a Mr. Coffee espresso machine.

What You’ll Need To Get The Job Done

  • A damp microfibre cloth
  • A toothpick or small dull needle
  • Cleaning toothbrush
  • White vinegar and water solution
  • Lemon juice and water solution
  • Hot soapy water

How To Do It

Step 1 - Prep Your Machine & Space

Turn off the machine and unplug your Mr. Coffee Cafe Barista power cord. Gather the supplies above and situate everything near your sink and bin.

Fill a sink or container with hot soapy water and prep a damp microfibre cloth.

Alternatively, you can mix a 1:1 solution of white vinegar and hot water or lemon juice and hot water to wash your parts in.

Step 2 - Clean and Remove Frothing Aid

Wipe down your milk frother with the damp microfibre cloth, making sure to scrub at the entrance to remove any clogs or dried milk with the toothbrush or toothpick.

You may need to remove the frothing aid to get at the stubborn stuck spots. Press the frothing tube button to remove any debris once done.

Step 3 - Remove And Clean External Removable Parts

Remove the drip tray, filter basket, reservoir, brew head, and carafe before washing them in warm soapy water.

You can scrub any stubborn spots with the toothbrush, damp cloth, or toothpick, depending on how narrow the area is.

If you are struggling, let them soak for a while before scrubbing again. Once done, let these parts air dry.

Step 4 - Clean The Knock Box, Portafilter, And Water Reservoir

If applicable, empty your knock box and portafilter before washing and air drying them. If you have a removable water reservoir, empty it and wash it the same way.

We do not recommend putting any of these external parts in the dishwasher as they may become damaged in the cleaning cycle.

Step 5 - Clean The Coffee Filter and Grinder

If your model has a coffee grinder, open it up according to manual instruction, empty the old beans and brush away any old coffee grounds. Refill with new beans and seal back up.

Step 6 - Wipe Down The Outside Of Your Mr. Coffee Machine

Wipe the housing of the machine down with your soft wet cloth. Do not use harsh or abrasive cleaners and scouring pads, as this will damage the stainless steel finish.

A damp cloth is perfect for getting the job done while maintaining its finish.

Step 7 - Dry And Reassemble Your Espresso Machine Parts

Once all of your external parts are washed and completely dry, reassemble them in their rightful places. Plug in and turn on your clean Mr. Coffee machine.

While quick and easy, these steps ensure that your coffee-making routine remains smooth sailing between deep cleaning sessions.

Always remember to rinse and refill your water reservoir, check on the steam system, and remove any old coffee grounds.

Deep Cleaning Of Your Mr. Coffee Espresso Machine

Your machine’s outer parts are not the only pieces that need maintenance. The inside of espresso machines is both where the magic happens and where unseen issues can occur.

Your water supply has various levels of small white deposits. These are minerals, or mineral deposits, often made of calcium and magnesium deposits.

While these are not harmful to you, a build-up of these deposits can adversely affect the effectiveness of your machine and the quality of your brews.

A build-up of hard water deposits and limescale can lead to clogged parts and excess wear, limiting the lifespan of your machine and creating poor brews.

The best way to deal with these is to delime the water reservoir and other internal parts frequently, particularly if you are living in areas with high levels of limescale in your water supply.
