Brewing coffee at home has become more and more popular in the coffeeholic community. If you also expect to enjoy a piping hot cup of joe every morning in your kitchen, you must have a coffee maker. However, you might sometimes wonder why your coffee doesn’t taste good although you have fresh uniform coffee ground and a fantastic coffee machine on hand.

In that case, you should ask yourself if your machine is clean or not. The more times you brew coffee, the easier the coffee maker gets dirty. Coffee stains, oil residue, or mineral deposits can be stuck in your coffee maker over time if you don’t occasionally wash it.

In fact, there are so many familiar ingredients that you can easily find in your kitchen to clean your coffee making machine. When natural cleaning agents cannot help you out, it’s time to think about chemicals.

How To Clean A Coffee Maker With Chemicals?

Using chemicals to wash your coffee machine is not a trick. Don’t forget to wear a pair of gloves to protect your hands from contacting directly to chemicals. The general instruction below can be applied to any chemical you opt to bring back the cleanness to your coffee maker.


The very first step is to prepare a solution from the chemical with water. You should use lukewarm water because it would help dissolve the chemical powder entirely and keep your machine away from being clogged. The ratio can vary depending on each kind of chemical, so you better check the instruction printed on the label.

First wash

Pour the prepared mixture to the water reservoir and let the machine run as brewing coffee. This process will allow the chemical solution to go through every part of your coffee maker.

Wash all the removable parts

Take all the removable parts out and wash them with soap and warm water. You can opt for washing with hands, or throw them into the dishwasher. If your carafe seems to have so many mineral deposits, you can pour the solution to the pot and let it sit for a few minutes. You will see how easy the stubborn buildups come off when gently washing.


This step is ultra important to ensure that there is no chemical left in the machine. You should use cold and clear water to fill the water chamber, and start brewing it. This process can be executed several times, depending on how harmful the chemical is.

Clean the exterior

When cleaning the inner of your coffee machine is done, then washing the outer is just a piece of cake. Use that prepared solution to wipe out the outside of the coffee maker. The final step is letting every single piece of your machine fully dry before reassembling and brewing coffee.

CLR stands for calcium, lime, and rust. It means that this chemical has the ability to remove the three stubborn buildups in your coffee machine. However, this heavy-duty cleaning agent should only be used as the last resort when anything else doesn’t work. The reason is CLR is literally toxic, and you need to clean your coffee maker super carefully, or you will accidentally swallow toxic.

You should use one part of CLR to eight parts of water to create the proper solution. One notable thing is CLR is not recommended to clean the espresso machine, Keurig, Gevalia, or Cuisinart coffee maker.

Denture tablets

You can clean your coffee maker with expensive cleaners, or stick with a cheap way like using denture tablets. This ingredient can amaze you with the ability to make your coffee machine fresh again. It’s not only inexpensive but also non-smell, so using denture tabs won’t leave any unpleasant odor on your coffee. Two tablets are enough for each cleaning time.

Lemi Shine

Lemi Shine is a chemical but is considered a safe one. Using the Lemi Shine product to clean your coffee machine will help remove the hard stains and deposits without leaving any toxic residue. However, you need to make sure to not use Lemi Shine in enamel-coated products and silver. Two tablespoons of Lemi Shine Booster work with 48 oz warm water is our recommended ratio to clean your coffee making machine.


If you are wondering whether bleach can be a cleaning agent for your coffee machine or not, the answer is no. This harsh chemical is advised to never use to clean a coffee maker, or you will make your morning cup harmful.

If you accidentally clean your coffee machine with a bleach solution, there is still a way to fix it, as long as the bleach is no more than two teaspoons in one gallon of water. You can flush the mixture out by running the brew cycle about four to five times with clear water. In case bleach is stronger, we are afraid that you have to say goodbye with your machine, or your morning coffee will have bleach in it.


Ammonia is known as an effective cleaner, but not for a coffee machine. You can use an ammonia solution to clean your floors, glass, microwaves, or an oven. These things are more comfortable to be wiped by just a damp cloth soaked in the ammonia solution. That means you can only wash the removable parts of your coffee maker with a very diluted ammonia solution, and you need to rinse them carefully later on. Unfortunately, it doesn’t work as other chemicals to run through the whole machine to clean.

Dish soap

Like ammonia, dish soap is an amazing cleaning agent. The name has told us about its function, to wash dishes. Therefore, it’s possible to wash the removable parts of the coffee maker with dish soap and water to remove the stains and smell. It would be best to use fragrance-free dish soap to avoid the soap smell being linger in your morning cup. However, you cannot brew the dish soap to clean your coffee machine because it will bubble and destroy the inner components.

Hydrogen peroxide

Hydrogen peroxide is a chemical compound that is viscous than water. It is commonly used as a bleaching agent, and you can totally use hydrogen peroxide to clean your coffee maker. One cup of hydrogen peroxide combines with two cups of water will help eliminate coffee stains in your coffee machine. The result will surprise you with a fresh and clean coffee maker.
