Why Clean the Coffee Maker Though?

Because things such as the hard water deposits (especially if you are using tap water) and natural coffee oils can mess up the taste of your cups.

On the other hand, scale buildup and other impurities can even affect the way your coffee maker works.

A coffee maker that’s frequently used will build up stubborn residue that you can’t get rid of by simply running hot water through it.

Parts of coffee grounds might start slowly building up in the filter basket and carafe, bit by bit if you don’t do a throughout cleaning after each brew.

But do you know what the grossest thing about not cleaning your coffee maker is?

It’s that your unit is probably crawling with germs, mold, and bacteria.

No matter how acidic your coffee is, it won’t drive away those nasty parasites.

The only way to cast impurities and stains aside is to use a natural, gentle and acidic cleaner – i.e. baking soda.

What Will Happen if I Don’t Clean My Coffee Maker?

Many unpleasant things ranging from your java tasting “bleh” to your brewer simply refusing to work anymore.

The build-up of residue in your coffee maker can cause:

  • Your coffee to taste bitter
  • Clogging and blockages that will spoil the machine’s performance
  • Your coffee machine will produce a burnt smell

Do you need any more valid reasons as to why you SHOULD maintain your coffee brewer properly by cleaning it every now and then?

How to Clean Your Coffee Maker with Vinegar/Lemon and Baking Soda?

Here’s how:

  • Clean the inside of the machine with vinegar and the carafe, pot, heating plate, and thermos with baking soda.

However, be careful not to mix these two ingredients i.e. baking soda with vinegar.

Why? Because the fizzing reaction between baking soda and vinegar is harmful to the inner components of your brewer and will eventually lead to rust.

Yet, you can mix soda and lemon to create a sort of a cleaning paste.

Then, you can use this paste to clean the heating elements and the exterior of your coffee maker.

Not only is this cleaning solution a brilliant and inexpensive option, but it will also remove grime and mold build-up from the machine.

How to Clean Your Keurig Coffee Maker?

You can either use a commercial cleaning product or clean your Keurig with vinegar.

And this is how you do it:

  • Pour two cups of undiluted vinegar into the reservoir and leave it to sit overnight
  • Run a regular brewing cycle in the morning, then dispose of the content
  • Brew a couple of cups if you have a single-serve machine.
  • Repeat the process until vinegar is completely gone

Now, Keurig and Bunn coffee machines come with built-in alert mechanisms so you don’t have to guess whether you need to descale your coffee maker or not.

Moreover, having a cleaning product is definitely a ready-made but hefty solution.

On the other hand, undiluted vinegar is a budget-friendly option that does the trick in the same way any regular cleaning product does.

Keep in mind that as soon as you notice your Keurig has started running more slowly, it is a clear sign it needs proper cleaning.

Watch out for other red flags such as funky and odd smells coming out of it.

In essence, apart from keeping your java delicious, cleaning your Keurig with undiluted vinegar will extend the unit’s lifespan as well.

Did somebody say coffee? Two shots of espresso for me, thanks. Oh, nevermind - I'm Simon, nice to e-meet you, dear CoffeeLifior! I like to write, drink coffee and I believe in Jesus. Highly-caffeinated drinks are my thing, but you can occasionally see me sip on decaf (my wife never finishes her coffee). Speaking of which, I'm off to grab another cup of caffeinated goodness now, laters!
