Why You Should Clean Your Coffee Maker

All of us, coffee enthusiasts, love our morning coffee. It saves us a trip to Starbucks and is also wallet-friendly. But here’s the thing, your Bunn’s coffee maker needs maintenance and cleaning every once in a while. Unless you’re okay with a moldy coffee with a taste of bacteria, you should give your coffee maker a thorough cleaning session at least once every 3 months. The water left inside your coffee maker is the cause behind the growth of mold and minerals in your Bunn’s coffee machine. If left uncared for, your Bunn’s coffee maker might disappoint you with its coffee brewing services. So, without further ado, let us get into our main topic for today of how to clean the Bunn coffee maker.

Cleaning Bunn Coffee Maker

Before we start the cleaning procedure, let us tell you the things you’ll need.

  • Vinegar
  • Water
  • Soap
  • Cloth
  1. The first thing you want to do is clean the external body of the coffee maker. Use the cloth and apply some soapy water on it; now, clean the surface of the coffee maker.
  2. Try reaching for tight spots where dirt might have been built up. Use the cloth to take care of it.
  3. Now pour the vinegar into the brewing cup till it is almost full, and then pour it inside the brewer. Plugin your coffee machine and power it up.
  4. Press the brew button and watch the coffee maker brew hot vinegar into the same cup. This will make the vinegar circulate around the coffee maker and clean its internal body.
  5. Repeat this process of brewing vinegar 2-3x.
  6. Now it is time to clean the inner tank with water. Fill the cup with cold water and pour it into the brewer.
  7. Press the brew button again and brew it as if you brew coffee. Your machine will be cleaned from the inside out.

This is the simplest and most effective method of cleaning your very own Bunn’s coffee machine. You can use this method for Bunn’s mainstream single-serve, speed brew line, and multiple-server machines.

How to Clean Bunn Coffee Maker Without Vinegar

For folks who do not prefer vinegar, we recommend you go for other effective cleaning liquids. Coffee machines should be cleaned with mild descaling chemicals, and vinegar perfectly fits the ideal standard. However, if you’re picky about the cleaning solution, then you’re free to clean your coffee maker with any descaling solution. A baking soda solution or a simple disinfectant chemical are both great in erasing stains, mold, and minerals inside your coffee machine. Nonetheless, we advise you to go for whichever approach suits you best.

Before we wrap up, we want to give our readers a few tips regarding cleaning their coffee makers in general. So, here are some quick tips for you guys to make the cleaning process free from troubles.

Tips to Clean Your Coffee Maker

1. Always Pay Equal Attention to External and Internal Body

Many coffee machine owners tend to neglect the internal body of their coffee machines. They keep their coffee makers all shiny from the outside while on the inside, bacteria is partying on top of the mold beds in the water tank. The real deal is the internal body. If you can keep it clean, you can expect your machine to function smoothly.

2. Do Not Fully Disassemble Your Coffee Maker

There is no need to fully disassemble your coffee maker. You have the advantage of circulating the cleaning solution (vinegar) throughout the body of your coffee maker. Use it to its fullest and avoid disassembling the main components of the coffee maker to make things easier. As far as the minor parts are concerned, such as the needle or the filter storage, those can be detached to be cleaned.

3. Do Not Use Extreme Chemicals

The use of dense substances of high concentration can cause damage to your coffee maker. Be sure to only use mild solutions that can get the job done. You also do not have to fully use vinegar or any other chemical solution. If you’re a bit short, don’t hesitate to add some parts water. As long as the water is equal to or less than the cleaning solution, you can expect your cleaning process to be successful.
