Poor coffee taste or machine performance? Your Keurig likely needs a good cleaning. In this guide, you’ll learn step-by-step how to clean a Keurig coffee maker thoroughly to enjoy fresh, delicious brews again.
Having a Keurig makes it easy to brew a perfect cup of coffee at home. However, like any appliance, Keurigs require regular cleaning and maintenance to continue operating at peak performance. Over time, mineral buildup, residue, and bacteria can accumulate inside, clogging the machine and tainting your coffee’s flavor.
This post covers why cleaning your Keurig is crucial, what supplies you need, and walks through a complete guide on how to clean a Keurig coffee machine. We’ll also discuss descaling for deeper cleaning, maintenance tips, and troubleshooting common issues.
Why Clean Your Keurig Coffee Maker?
Cleaning your Keurig machine regularly is essential for several reasons:
- Eliminate Mineral Buildup: If you live in an area with hard water, mineral deposits like calcium and limescale can quickly build up inside the water reservoir and tubing. This buildup can clog the machine, causing slow brew times or complete malfunction.
- Remove Bacteria and Residue: The warm, moist environment inside a coffee maker is ideal for bacteria growth. Old coffee grounds, residue, and even mold can accumulate, affecting the taste and safety of your beverages.
- Maintain Great Coffee Flavor: Built-up residues and mineral deposits alter the taste of your coffee over time. Regular cleaning ensures you enjoy fresh, delicious coffee without any off-flavors.
- Prolong Machine’s Lifespan: Neglecting to clean your Keurig puts unnecessary strain on the internal components. Proper maintenance helps prevent costly repairs and keeps your machine running smoothly for years.
What You’ll Need
Before getting started, gather these basic supplies:
- Mild dish soap
- Clean cloth or sponge
- Soft bristle brush (toothbrush works)
- Paper clips or toothpicks
- White vinegar or descaling solution
- Access to water for rinsing
Having all your materials ready makes the cleaning process much easier. Let’s look at the step-by-step process next.
Step-by-Step Guide to Clean a Keurig
Follow these instructions to thoroughly clean the exterior and internal components of your Keurig coffee maker:
Disassembling and Washing Removable Parts
- Unplug the machine and let it cool completely before starting. You don’t want any electrical components getting wet.
- Remove the water reservoir and wash it with dish soap and warm water. Use a soft brush to scrub away any stuck-on residue. Rinse thoroughly.
- Take out the K-cup holder and funnel piece. This pops out for easy removal. Wash all removable parts in soapy water and rinse well.
- Remove and rinse the drip tray that catches overflows. You can use a brush to scrub out any dried coffee grounds.
- If your machine has a reusable filter, remove it and let it soak in vinegar for 10-15 minutes before scrubbing clean.
- Let all the washable components fully air dry before reassembling.
Cleaning the K-Cup Holder and Needles
The K-cup holder and needle that punctures the pods is a prime area for clogs to develop. Take some extra time here:
- Use a paperclip or toothpick to dislodge any stuck coffee grounds inside the holder and around the needle entrance.
- Unclog the needle itself by inserting the paperclip and gently moving it around to remove any blockages.
- Rinse the holder and needle under warm running water when finished to wash away any loosened debris.
Wiping Down the Exterior
Don’t forget to clean the outside of the machine too:
- Dampen a clean cloth with water and dish soap.
- Gently wipe down the exterior surfaces to remove any splatters, dust, or fingerprints.
- Pay close attention to the area around the K-cup holder which can get sticky.
- Dry with a clean towel or let air dry fully before reassembling.
With all the components cleaned and dried, you can now reassemble your Keurig. It’s also a good idea to run a cleansing brew with just water to flush out any soap residue inside.
How to Descale Your Keurig
While regular washing cleans the exterior and removable parts, descaling is a deeper cleaning process that removes mineral buildup inside the tubing and heating components. Descaling your Keurig periodically is crucial for optimal machine performance.
What is Descaling?
Descaling refers to removing the hard water mineral deposits (like calcium and limescale) that accumulate over time. This buildup can clog the machine’s interior tubing, heating element, and valves – eventually causing breakdowns if not addressed.
When to Descale
How often you need to descale depends on your water hardness level and frequency of use:
- For daily Keurig users with hard water: Descale every 3 months
- For daily users with soft water: Descale every 6 months
- For infrequent users: Descale every 6-12 months
If you start noticing longer brew times, clogs, or bitter off-flavors in your coffee, that’s a sign it’s time for a descaling.
Descaling Process with Vinegar
White vinegar is an effective, inexpensive descaler you likely already have at home. Here are the steps:
- Mix equal parts white vinegar and water in the reservoir until full. The vinegar helps dissolve the mineral deposits.
- Place a mug or container on the drip tray and run the brew cycle until the “Add Water” light comes on. Discard the hot vinegar water as it cycles through.
- Let the vinegar solution sit for 30-60 minutes while the machine is off to allow more descaling time.
- Drain the remaining vinegar solution and refill the reservoir with fresh water.
- Brew plain water through the machine until the reservoir is empty to thoroughly rinse away any vinegar residue.
- Consider running 2-3 more plain water brews to ensure all vinegar is flushed out before making coffee again.
Descaling with Keurig Solution
Keurig also sells their own branded Descaling Solution made specifically for their machines:
- Pour the entire bottle of Descaling Solution into the water reservoir and fill the rest with water to the max line.
- Run the brew cycle until the “Add Water” light comes on.
- Turn the machine off and let it soak for at least 30 minutes.
- Resume brewing cycles with fresh water until the reservoir is emptied.
- You may need to let the machine sit unplugged overnight before using again to ensure no descaler remains.
Follow the manufacturer’s instructions for best results with their solution. Proper descaling not only improves coffee taste but also extends your Keurig’s lifespan.
Tips for Regular Keurig Maintenance
In addition to cleaning and descaling, here are some other tips to keep your Keurig in top shape:
- Clean the removable parts weekly if using daily. This prevents excessive buildup.
- Replace the water filter every 2-3 months. This improves water quality for brewing.
- Run a cleansing brew without a K-cup every few weeks. Helps flush out any residues.
- Wipe down the exterior after each use. This prevents sticky spills from drying on.
- Descale with vinegar every few months even if not using often. Prevents clogs while in storage.
- Check for any mineral buildup on heating components during descales. Scrub off carefully with a soft brush.
Proper preventative maintenance saves you the hassle and cost of repairs or replacements down the road.
Troubleshooting Common Keurig Issues
If you run into any of these common problems with your Keurig, a good cleaning is likely the solution:
Slow brew times or clogs: This indicates a mineral or grounds blockage that needs to be cleared. Try descaling first before any other fixes.
Strange tastes or odors in coffee: Old residues, bacteria growth, or mineral buildup can cause off-flavors and funky smells in your brew. A thorough cleaning and descaling should resolve this.
Leaks or overflows: Clogs can cause internal pressure to build up, resulting in leaks or the machine overflowing. Descale first, and check for any obstructions in the tubing or sprayhead.
Machine not brewing properly: If your Keurig isn’t brewing at all or only dispensing a small amount of coffee, mineral buildup may be blocking the water flow. Descaling is usually an effective fix.
Inconsistent brew temperature: Mineral scale can impair the heating element’s ability to reach the proper brew temperature consistently. Descaling helps restore optimal heating.
Error codes or warning lights: Many Keurig error codes stem from mineral buildup issues that require a descaling cycle to reset the machine.
If cleaning and descaling doesn’t resolve the problem, you may need to check for any loose internal components or damage. Consulting the machine’s user manual for troubleshooting guidance is recommended before attempting any repairs yourself.
