If you’re wondering how do i clean my Mr Coffee coffee maker, you’re taking the right step for better coffee. Keeping your Mr. Coffee machine clean ensures every cup tastes as good as the first one you brewed. A clean machine removes old oils and mineral deposits that make coffee taste bitter or sour. It also helps your appliance last longer and work more efficiently.
This guide provides simple, step-by-step instructions for every part of your machine. We’ll cover daily care, weekly cleaning, and deep descaling. You’ll learn what supplies you need and how to handle common problems. Let’s get started.
How Do I Clean My Mr Coffee Coffee Maker
A thorough clean involves multiple steps targeting different components. You should clean the carafe and filter basket daily. The water reservoir and internal parts need attention weekly or monthly. Descaling, which removes hard water scale, is crucial every 1-3 months depending on your water hardness.
Gathering your supplies first makes the process smoother. You likely have most items at home already.
Essential Supplies You Will Need
Before you begin, collect these items. Using the correct materials prevents damage to your coffee maker.
- White vinegar or a commercial coffee maker descaler
- Fresh, cold water
- Mild dish soap
- A soft sponge or cloth (non-abrasive)
- A soft-bristled brush (an old toothbrush works perfectly)
- Paper towels or a clean drying rack
Why Vinegar Works for Descaling
White vinegar is a mild acid that dissolves calcium and magnesium deposits, known as limescale. These minerals build up from your water and clog the internal heating tube and water channels. A clogged machine heats water slower and brew inconsistently. Vinegar is a safe, affordable, and effective solution for most Mr. Coffee models.
Daily Cleaning Routine
This quick routine takes just a minute but makes a big difference. It prevents stale coffee oils from ruining your next pot.
- After brewing, discard the used paper filter and coffee grounds immediately.
- Wash the glass carafe and plastic lid with warm, soapy water. Use your soft sponge to wipe the inside thoroughly. Rinse well to remove all soap residue.
- Wash the permanent gold-tone filter (if you use one) under running water. Use your soft brush to scrub away any fine grounds stuck in the mesh.
- Wipe the warming plate with a damp cloth to remove any coffee spills or drips. This prevents them from baking onto the hot surface.
- Leave the carafe and filter basket to air-dry completely before the next use. This prevents musty odors.
Weekly Deep Clean Of Removable Parts
Once a week, give the removable components a more detailed clean. This tackles buildup that daily rinsing misses.
Start by unplugging your Mr. Coffee machine and letting it cool completely. Never immerse the main base unit in water.
- Remove the water reservoir lid and the filter basket holder (the part you put the filter in).
- Wash these parts in warm, soapy water. Pay special attention to the small holes in the bottom of the filter basket holder where water drips through.
- Use the soft-bristled brush to clear any debris from these holes. A toothpick can help if they are very clogged.
- Clean the exterior of the machine with a cloth dampened with a mild soap solution. Wipe it dry to prevent water spots.
- Ensure all parts are completely dry before reassembling the coffee maker.
Step-By-Step Descaling Process
Descaling is the most important maintenance task. It cleans the inside parts you can’t see. Follow these steps carefully about every three months, or more often if you have hard water.
Preparing The Vinegar Solution
The standard ratio is equal parts white vinegar and fresh water. For a full 12-cup machine, you will typically use 2 cups of vinegar and 2 cups of water. Always check your model’s manual for any specific instructions, as some newer models may recommend different ratios.
Never use straight vinegar, as it can be to strong for some internal components. Also, avoid using bleach or other harsh chemicals.
Running the Descaling Cycle
- Fill the water reservoir with the vinegar-water solution you prepared.
- Place a clean filter in the basket. You do not need to add coffee grounds.
- Put the empty carafe back onto the warming plate.
- Turn on the coffee maker and let it run through a full brew cycle as if you were making coffee.
- When the cycle is complete, turn off the machine and let the vinegar solution sit in the carafe and within the hot internal tubing for 15-20 minutes. This soaking time helps break down heavy mineral deposits.
Rinsing Thoroughly After Descaling
This step is critical. Any leftover vinegar will ruin your next several pots of coffee with a sour taste and odor.
- Discard the vinegar solution from the carafe.
- Rinse the carafe thoroughly with fresh water.
- Fill the water reservoir completely with fresh, cold water only.
- Place the clean carafe back in position and run another full brew cycle without coffee or a filter. This flushes the system.
- Repeat the rinse cycle with fresh water one more time. For stubborn vinegar smells, a third rinse may be necessary.
- After the final rinse, run one more cycle with just water and then pour it out. Taste the water from the carafe. If you detect any vinegar taste, continue rinsing until the water runs completely clear and tasteless.
Cleaning Specific Mr Coffee Components
Some parts need special attention. Here is how to handle them.
Cleaning The Glass Carafe
Coffee oils stain glass over time. For tough stains, make a paste with baking soda and water. Apply it inside the carafe, let it sit for a few minutes, and scrub gently with your sponge. For mineral rings, a soak in a vinegar-water solution will dissolve them. Always rinse extremely well after using baking soda or vinegar.
Maintaining The Gold Tone Permanent Filter
These reusable filters are great but require care. Soak it weekly in a bowl of hot water with a little dish soap. Scrub it gently with your soft brush to remove all oil film. Rinse until the water runs clear. Inspect it regularly for small tears or bends in the mesh that could let grounds through.
Addressing the Warming Plate
Baked-on stains on the warming plate are common. Make sure the machine is unplugged and completely cool. Create a paste from baking soda and a few drops of water. Apply it to the stained area on the plate. Let it sit for an hour, then gently scrub with a damp, non-scratch sponge. Wipe clean with a damp cloth. Do not pour water directly onto the warming plate.
Troubleshooting Common Cleaning Issues
Sometimes, you’ll encounter specific problems. Here are solutions.
Machine Won’t Brew Or Brews Slowly
This is almost always caused by severe limescale clogging the internal tubes. Perform the descaling process outlined above. If the problem persists after two descaling cycles, you may need to use a commercial descaler formulated for coffee makers, which can be stronger than vinegar. Follow the product instructions exactly.
Persistent Mold Or Mildew Smell
Mold can grow in damp, dark places like the water reservoir. To eliminate it, create a cleaning solution of 1 tablespoon of bleach to 1 quart of water. Use this solution to wipe out the entire reservoir and lid thoroughly. Then, run multiple rinse cycles (at least three) with fresh water only through the brew cycle to ensure all bleach is removed. Always ensure the reservoir is left open to air dry between uses to prevent mold’s return.
Coffee Tastes Bad After Cleaning
A vinegar taste means inadequate rinsing. Run several more fresh water brew cycles until the taste is gone. A soapy taste means the carafe or filter basket wasn’t rinsed well enough after washing. Wash them again with clear water and no soap, then dry. A bitter or off taste that wasn’t there before could indicate a damaged carafe or component that needs replacing.
Preventive Maintenance Tips
Good habits reduce the need for heavy cleaning. Follow these tips to keep your Mr. Coffee in top shape.
- Use filtered water if your tap water is very hard. This dramatically reduces limescale buildup.
- Empty any unused water from the reservoir after brewing if you won’t use the machine for a day or two.
- Leave the lid off the carafe and the reservoir open after use to allow moisture to evaporate.
- Wipe up spills on the warming plate immediately, before they bake on.
- Replace paper filters if you switch to a permanent filter, as the brewing mechanism is calibrated for the flow rate of paper filters.

How Often Should I Clean My Mr Coffee Machine?
You should clean the carafe and filter basket after every use. Perform a weekly clean of all removable parts. Descale the internal system every one to three months, depending on your water hardness and how frequently you use the machine.
Can I Use Lemon Juice Instead Of Vinegar To Descale?
Yes, lemon juice is a citric acid and can work as a descaler. Use the same ratio as vinegar, mixing equal parts lemon juice and water. However, it may be less effective on heavy buildup and is often more expensive than white vinegar.
What Is The Best Way To Clean A Mr Coffee Machine Exterior?
Unplug the unit and let it cool. Dampen a soft cloth with a mild soap and water solution. Wipe down the plastic housing, being careful to avoid any electrical openings or the control panel. Immediately dry it with a separate clean cloth to prevent streaks.
Why Is My Coffee Maker Making A Gurgling Noise?
A gurgling noise often indicates a blockage in the internal tubing or the one-way valve. This is usually due to limescale. A thorough descaling process should resolve the issue. If it continues, consult the manufacturer’s manual for your specific model.
Is It Safe To Put The Mr Coffee Carafe In The Dishwasher?
Most Mr. Coffee glass carafes are dishwasher safe, but you should always check the manual or the bottom of the carafe for a dishwasher-safe symbol. The plastic lid, filter basket, and permanent filter should typically be washed by hand to prevent warping or damage from high heat.
