What Type of Vinegar Should I Use to Clean My Keurig?

The vinegar you use to clean your Keurig coffee maker is critical to its efficacy. This usually requires white distilled vinegar. Most people prefer white distilled vinegar for cleaning Keurig coffee makers. Some reasons to choose white vinegar:

A Neutral Flavor

White vinegar has a neutral taste and smell. This ensures no taste or odor remains after Keurig cleaning. Your coffee should taste like coffee, not vinegar.


White vinegar is acidic enough to dissolve Keurig mineral deposits and scale. This is essential for coffee maker performance.


Keurig internals are less likely to discolor with white vinegar. Colored vinegars like apple cider or red wine vinegar may stain.


Most supermarket stores sell white distilled vinegar, making it convenient for many.

White vinegar and water are mixed in equal proportions and pushed through your Keurig to clean it. Descaling and cleaning your Keurig model requires manufacturer instructions.

Is It Safe to Use Vinegar to Clean a Keurig Coffee Maker?

Cleaning a Keurig coffee maker with vinegar is usually safe. For eliminating mineral deposits, scale, and coffee residue from the machine, vinegar is often advised and successful. However, some significant factors must be considered:


Water must be added to vinegar to clean your Keurig. One part white distilled vinegar to one part water is typical. This prevents the vinegar from being too harsh and leaving a strong vinegar taste or odor in your coffee machine.

Thoroughly Rinse

You must repeatedly rinse your Keurig with normal water after using a vinegar-water solution. This flushes all residual vinegar from the system.

Follow the Manufacturer’s Directions

Manufacturers may provide cleaning and descaling instructions for different Keurig models. Following these guidelines is crucial for equipment maintenance.


It’s safe to use vinegar to clean most Keurig machines, but verify the user manual or manufacturer’s instructions for your model.

When used properly, vinegar cleans most Keurig coffee makers safely. It removes mineral buildup and keeps your computer functioning. Dilute it, rinse well, and follow the manufacturer’s instructions to retain coffee quality and taste.

How to Clean Keurig with Vinegar

Cleaning your Keurig coffee maker with vinegar is easy and effective for optimal function and taste. Below are steps for cleaning a Keurig with vinegar:

How to clean a keurig coffee maker with vinegar

Materials You’ll Need

  • White distilled vinegar
  • Water
  • A clean cloth or paper towels
  • A mug or bowl
  • A toothbrush or a paperclip (for cleaning the needles)

Step 1: Get Supplies

You must gather all the supplies before cleaning your Keurig. This guarantees you have everything you need, making cleaning easy. White distilled vinegar, water, a clean cloth or paper towels, a mug or bowl, and a toothbrush or paperclip are all you need. These are everyday products, so you won’t need anything special.

Step 2: Empty and Remove Water Reservoir

Before brewing, you pour water into your Keurig’s water reservoir. Cleaning must begin with removing this reservoir. Make sure it’s waterless first. Pour any residual water into your sink. Removing the reservoir lets you clean your Keurig inside.

Step 3: Disassemble and Clean Removable Parts

Let’s talk about Keurig’s removable parts. These include the drip tray and K-cup holder. Remove these parts gently and wash them in warm, soapy water. Rinse them well to remove soap residue. Let them air-dry after rinsing. Cleaning these parts periodically prevents coffee dirt and optimizes machine performance.

Step 4: Make a Cleaning Solution

This is the magic step. You’re making a basic yet efficient cleaning solution with white distilled vinegar and water. White distilled vinegar, a natural cleaning, breaks down mineral deposits and buildup in your Keurig. Fill your water reservoir halfway. Add water to the reservoir.

Descale and clean your machine’s internal parts with this diluted vinegar solution to maintain it in peak shape. The vinegar scent may be intense, but it will fade after cleaning. The vinegar-water combo keeps your Keurig brewing wonderful coffee, so it’s worth it.

Step 5: Brew a Cleanser

After making a vinegar-water solution in the water reservoir, clean your Keurig. Place an empty mug or dish on the drip tray where you usually put your coffee. Start your Keurig and choose the largest cup size. This technique should not involve a coffee pod (K-cup).

This is a purifying brew. Your Keurig will push vinegar and water through its parts. Descales and removes mineral deposits and coffee residues that may be compromising your coffee maker’s flavor and function.

Step 6: Repeat Cleansing Brew

One cycle of the cleansing brew may not clean your Keurig, especially if you haven’t cleaned it recently. To flush out all vinegar and prevent your coffee from tasting like vinegar, repeat this cleansing brew process one or two more times with fresh water. Use an empty mug or bowl to catch the liquid again.

Step 7: Clean Needles

The small, pointy Keurig needles puncture K-cups as you brew coffee. These needles can become blocked with coffee grounds or other debris, impacting water flow and coffee flavor. For safety, unplug and switch off your Keurig to clean them. A toothbrush or straightened paperclip can gently clean needles of coffee grounds and grime. Be careful not to damage the needles.

Step 8: Rebuild and Replace

After cleaning the needles and checking for obstructions, reassemble your Keurig. Remember those removable bits you cleaned earlier? Put them back together now. Before refilling your coffee machine, check sure these parts are dry. We don’t want mold or mildew in our Keurig, therefore this is vital!

Step 9: Rinse

Fill your Keurig reservoir with fresh water to remove vinegar and soap. Rinse your Keurig several times. As before, catch the water in an empty mug or bowl. Repeat these rinse cycles until the vinegar smell disappears and the water is clear. This keeps your coffee from tasting like vinegar and lets you enjoy it without any unwanted flavors.

Taking these measures seriously means taking good care of your Keurig coffee maker. Cleaning and descaling your machine regularly improves coffee flavor and appliance life. After cleaning and refreshing your Keurig, you can brew your favorite coffee or tea with confidence, knowing it will taste great. Happy brewing!

How Often Should I Clean My Keurig with Vinegar?

Your water quality, consumption trends, and personal tastes determine how often you should clean your Keurig with vinegar. However, vigorous cleaning with vinegar every three to six months is recommended.

Consider these factors while choosing a cleaning schedule:

Water Hardness

In hard water areas, Keurig mineral deposits can build up faster. It may need to be cleaned every three months to prevent scaling.


How often you use Keurig matters. If you consume a lot of coffee and use your machine often, it may collect coffee residue faster. In this instance, cleaning every three to four months may be advantageous.

Taste Preferences

Your coffee may taste different if you clean it. Mineral buildup or residual vinegar can cause your coffee to taste odd or have a vinegar-like aftertaste.

Advice from Manufacturers

Check your Keurig’s user handbook for manufacturer cleaning frequency recommendations. Models may have special requirements.

Along with these general rules, emptying and cleaning the water reservoir, drip tray, and K-Cup container weekly or as needed is a good idea.

Can I Use Apple Cider Vinegar Instead of White Vinegar for Cleaning My Keurig?

White vinegar is best for Keurig cleaning due to its neutral flavor and mild acidity, although apple cider vinegar can be used if white vinegar is unavailable. However, some significant factors must be considered:

Considerations for Flavor

Flavor distinguishes apple cider vinegar from white vinegar. Due to fermentation, apple cider vinegar tastes fruity and slightly sweet, while white vinegar is neutral and odorless. When you clean your Keurig with apple cider vinegar, your coffee may taste or smell apple-like. Those sensitive to coffee flavors may not like this.


Dilute apple cider vinegar to reduce taste transfer and discoloration. One part apple cider vinegar to one part water is typical. A diluted vinegar reduces its acidity, making it less likely to stain and impact coffee taste.


After brewing the diluted apple cider vinegar solution in your Keurig, rinse it well. To eliminate vinegar, flavor, and stains, flush the system repeatedly with plain water. You must rinse your coffee well to preserve its flavor.

Concerns about Stains

Apple cider vinegar may stain or discolor Keurig parts due to apple pigments. This highlights the importance of dilution and rinsing.

Apple cider vinegar can clean your Keurig instead of white vinegar, but it may discolor and taste different. It can be diluted and rinsed to reduce these concerns. For the most reliable and neutral cleaning without changing the coffee taste, white distilled vinegar is best.

Are There Any Alternative Methods to Clean a Keurig Machine without Vinegar?

Yes, you can clean a Keurig coffee machine without vinegar or if you don’t have any. Some other cleaning methods:

Citric Acid

Instead of vinegar, citric acid can clean your Keurig of mineral deposits and scale. Most supermarket stores sell powdered citric acid. Citric acid can clean your Keurig by diluting 1-2 tbsp with water like vinegar. Run the Keurig brew cycle without a K-Cup by adding citric acid to the water reservoir. After that, rinse the machine with normal water to remove all citric acid.

Lemon Juice

The citric acid in lemon juice makes it another natural option. Mix equal parts lemon juice and water to descale and clean your Keurig. To remove any lemony taste or odor, pour the lemon juice mixture into the water reservoir, run a brew cycle without a K-Cup, then rinse with plain water several times.

Business Descaling Options

Many firms offer Keurig-specific commercial descaling solutions. Citric acid is typically in these solutions. The best results come from following the manufacturer’s packing directions. Commercial remedies may be easier for vinegar haters because they are unscented.

Baking Soda

Baking soda removes coffee stains and odors well. To use, mix baking soda with a little water to produce a paste. Use a soft cloth or sponge to carefully scrub the K-Cup holder, drip tray, and removable pieces of your Keurig with the paste. Use plenty of water to remove every residue.

Tablets for Denture Cleaning

Some people clean their Keurig using denture-cleaning tablets. Follow the package instructions to dissolve one denture tablet in water. After adding the solution to the water reservoir, brew your Keurig without a K-Cup. To eliminate denture tablet residue, rinse the machine with normal water.

Your cleaning approach depends on your choices, resources, and needs.


Can I Clean My Keurig without Disassembling It?

Answer: You can run vinegar through your Keurig without disassembling it, but cleaning the drip tray, K-cup holder, and needles is essential for machine operation and hygiene. These parts collect coffee residue, mineral deposits, and mold over time, affecting coffee quality and Keurig’s performance. Regularly disassembling and cleaning these components keeps your machine clean and running well.

Can Vinegar Clean My Keurig’s Exterior?

Answer: You can clean your Keurig’s exterior with diluted vinegar. Dust, spills, and coffee splatters can build up on your coffee maker’s exterior. Dampen a towel or sponge with vinegar and gently wipe the exterior. Dirt and stains can be removed with vinegar’s natural cleaning qualities. To avoid vinegar residue on the exterior, rinse with plain water afterward. A last dry wipe will clean and freshen your Keurig.

What Should I Do If My Keurig Smells Vinegar after Rinsing?

Answer: Sometimes Keurigs smell like vinegar after rinsing. Repeat the rinse cycle with new water until the scent is gone. Rinsing the machine thoroughly removes vinegar residue, which causes the vinegar scent. Repeat the rinse process until the water is unscented to avoid vinegar-like coffee. This extra step ensures your Keurig is clean and ready to brew your favorite coffee without odors.

Why Should Keurig Needles Be Cleaned?

Answer: Keurig needles puncture K-cups during brewing, therefore cleaning them is essential. They can become clogged with coffee grounds and other debris, preventing water flow and decreasing coffee quality and quantity. Keeping the needles clean allows water to flow freely through them, ensuring your Keurig makes the greatest coffee every time.

Can I Use a Descaling Solution Instead of Vinegar?

Answer: Commercial coffee maker descaling solutions can replace vinegar. These treatments successfully remove mineral deposits and scale buildup from Keurig internals. For proper dilution and use, follow the manufacturer’s label directions. While vinegar is cheap and widely accessible, descaling solutions are convenient and provide comprehensive descaling for the best Keurig performance and lifetime.

Can I Use Vinegar in My Keurig? Does It Harm the Machine?

Cleaning your Keurig with vinegar is safe when done properly. A moderate acid cleanser, vinegar dissolves mineral deposits and coffee stains. It shouldn’t damage your machine if used properly. Dilute the vinegar with water as indicated in the cleaning handbook and rinse well. Undiluted vinegar may damage Keurig components because of its extreme acidity. Vinegar cleans your Keurig safely and effectively when used as indicated.

Can Bleach Clean My Keurig Instead of Vinegar?

Answer: Bleach is not recommended for Keurig cleaning. Bleach can leave strong scents and aromas that are hard to eradicate. Bleach can also affect coffee maker materials and performance. Cleaning and maintaining your Keurig with white distilled vinegar or a commercial descaling solution is safer and better. These bleach-free solutions remove mineral deposits, coffee stains, and mold.

Can I Clean My Keurig with Lemon Juice Instead of Vinegar?

Answer: Lemon juice can clean your Keurig instead of vinegar. Lemon juice removes mineral buildup and the machine smells due to its acidity. One drawback is that it may smell citrus. To avoid this, rinse with plain water many times after lemon juice cleansing. This will eradicate any remaining lemony fragrance, leaving your Keurig fresh and ready to brew your favorite coffee tastes.

If I Neglect to Rinse after Vinegar Cleaning, What Happens?

Answer: If you neglect to rinse your Keurig after vinegar cleaning, there’s a simple fix. Due to residual vinegar, your coffee may taste slightly acidic. Run several rinse cycles with fresh water until the vinegar smell disappears. This prevents vinegar flavor from ruining your coffee, so you may enjoy its rich taste uninterrupted.

Can Vinegar Also Clean the Water Filter?

It’s not recommended to clean the water filter using vinegar. The Keurig water filter removes pollutants and improves water quality. Vinegar cleaning may harm the filter, reducing its efficiency. Instead, replace the water filter every two months or as instructed in your Keurig user handbook. Changing the water filter regularly keeps your coffee maker producing the best coffee and filtering out impurities.

How Do I Clean My Keurig’s Exterior with Tenacious Stains or Coffee Spills?

A simple treatment for Keurig exterior stains and coffee spills. Mix baking soda and water to make a thick cleaning paste. Let this paste remain on the affected regions for a few minutes. Gentle abrasion from baking soda lifts stains and residue. After, use a soft cloth or sponge to scrub the stained areas. Thoroughly rinse with plain water and dry with a clean cloth. This procedure should remove tough stains and clean your Keurig.

Can I Dishwasher-clean the Drip Tray and K-cup Holder?
