Learning how to clean a coffee maker Mr Coffee is essential for any owner. Keeping your Mr. Coffee machine clean ensures every cup tastes as fresh as the first. A clean machine also works more efficiently and lasts much longer. This guide will walk you through every step, from daily care to deep monthly cleaning.
How To Clean A Coffee Maker Mr Coffee
A thorough clean involves several key areas: the carafe, the filter basket, the water reservoir, and the internal tubing. Neglecting any part can lead to off-flavors or even damage. We will break this down into simple, manageable tasks. Follow these steps to restore your brewer’s performance.
What You Will Need For Cleaning
Gathering your supplies first makes the process smoother. You likely have most items at home already. Here is what you need for a basic and effective clean.
- White vinegar or a commercial coffee maker cleaner
- Fresh, cold water
- Mild dish soap
- A soft sponge or cloth (non-abrasive)
- A small brush, like an old toothbrush or bottle brush
- Soft towels for drying
Daily And Weekly Cleaning Routine
Preventative maintenance stops big problems. A quick routine after each use keeps things sanitary and ready for the next brew. This takes just a minute but makes a huge difference.
After Each Use
Once you pour your last cup, start this habit. First, discard the used paper filter and grounds immediately. Then, rinse the glass carafe and plastic filter basket with warm water. Wipe the warming plate with a damp cloth to remove any coffee spills or drips. Let all parts air dry completely before reassembling.
Weekly Deep Rinse
Once a week, give the removable parts a soapy wash. Fill your sink with warm water and a little dish soap. Wash the carafe, lid, and filter basket thoroughly. Use the small brush to scrub the basket’s nooks and the carafe spout. Rinse everything well to remove all soap residue, as leftover soap will ruin your next pot of coffee.
Monthly Deep Cleaning With Vinegar
This is the most important process for descaling. Mineral deposits from water, called scale, build up inside the heating element and tubes. Vinegar’s acidity dissolves this scale. Plan to do this every one to three months, depending on your water hardness and usage.
- Prepare the Vinegar Solution: Mix equal parts white vinegar and fresh cold water. For a standard 12-cup Mr. Coffee, you will usually need about 2 cups of vinegar and 2 cups of water.
- Fill and Start: Pour the solution into the water reservoir. Place a clean filter in the empty basket, and put the empty carafe on the warming plate.
- Begin a Brew Cycle: Turn the machine on and start a full brew cycle. Let it run until about half the solution has brewed into the carafe.
- Pause and Soak: Turn the brewer off. Let the vinegar solution sit in the system for 30 to 60 minutes. This soaking time is crucial for breaking down mineral deposits.
- Complete the Cycle: Turn the machine back on and let it finish brewing the rest of the solution into the carafe.
- Rinse Thoroughly: Dump the vinegar from the carafe. Fill the reservoir completely with fresh cold water. Run multiple full brew cycles with just water—at least two or three—until no vinegar smell remains in the brewed water.
Cleaning The External Components
The outside of your machine needs attention too. Coffee splatters, fingerprints, and dust can accumulate. Unplug the machine and let it cool completely before you start.
Wipe the entire exterior with a cloth dampened with a mild soapy solution. Avoid getting water into any vents or the control panel. For the warming plate, a paste of baking soda and water can help remove stubborn stains; apply it gently with a cloth, then wipe clean. Dry everything with a soft towel.
Addressing Common Problem Areas
Some parts need extra focus. These spots often harbor old oils and grounds, which contribute to bitter tastes.
The Glass Carafe
Stains inside the carafe are normal but removable. For tough stains, fill it with a hot mixture of water and a few tablespoons of baking soda. Let it soak overnight. You can also add a handful of ice cream salt and swirl it around for gentle abrasion. Rinse extremely well afterwards.
The Filter Basket and Holder
Coffee oils cling to the plastic. Remove the basket and holder if your model allows. Soak them in hot, soapy water. Use the small brush to scrub the inside of the holder and the small holes in the basket where water drips through. Ensure no old grounds are trapped in the crevices.
The Water Reservoir
Mold or slime can form in the damp reservoir. Wipe it out regularly with a vinegar-water cloth. For a deeper clean, let a vinegar-water solution sit in the reservoir for 15 minutes before rinsing. Always leave the lid open when not in use to allow air circulation and prevent mildew.
When To Use Commercial Cleaners
Commercial coffee maker cleaners are a good alternative to vinegar. They are specifically formulated to dissolve coffee oils and mineral scale. They are often odorless, which some people prefer over the vinegar smell. Follow the package instructions carefully, as they can be more potent. Always run extra water cycles after using a commercial cleaner to ensure it is fully rinsed from the system.
Maintaining Your Machine For Longevity
Good habits extend your brewer’s life. Always use fresh, cold water. Consider filtered water if your tap water is very hard. Never run the machine without water in the reservoir, as this can damage the heating element. Store the machine in a dry place, and if you won’t use it for a while, give it a final vinegar clean and let it dry thoroughly before putting it away.
Troubleshooting Cleaning Issues
Sometimes problems persist even after cleaning. Here are solutions for common issues.
- Vinegar Smell Remains: Run two more water-only brew cycles. If it persists, try using a baking soda solution (2 tablespoons per reservoir of water) for one cycle, followed by several clear water cycles.
- Machine Runs Slow: This is usually due to severe scale buildup. You may need to repeat the vinegar cleaning process twice in a row, or use a stronger commercial descaling product.
- Coffee Tastes Bad: Ensure you rinsed all parts well after soap or vinegar washing. Old coffee oils in the basket or holder could be the culprit; give them an extra scrub.

Here are answers to some frequently asked questions about cleaning a Mr. Coffee maker.
How often should I clean my Mr. Coffee with vinegar?
You should descale your Mr. Coffee with vinegar every one to three months. If you use hard water or brew coffee daily, lean toward the monthly schedule. If you have soft water or use it less often, you can clean it every three months.
Can I use lemon juice instead of vinegar to clean my coffee maker?
Yes, lemon juice is a good natural alternative. Use the same method with equal parts lemon juice and water. However, it may be less effective on heavy scale buildup and can be more expensive than vinegar for regular use.

For daily care, rinse with hot water. For stains, soak with a baking soda and water paste. For stubborn films, use a bottle brush with a little vinegar. Avoid harsh scrubbers that can scratch the glass.
Why is it important to clean a coffee maker regularly?
Regular cleaning removes mineral scale that clogs the system and oils that turn rancid. This prevents bitter tastes, ensures proper brewing temperature, and helps your machine function correctly for years to come. A clean machine simply makes better coffee.
My machine has a “Clean” light. What should I do?
When the “Clean” indicator light turns on, it is signaling that descaling is needed. Follow the vinegar or commercial cleaner process outlined above. After completing the cleaning cycles, the light should reset automatically on most models. Consult your manual for model-specific instructions.
