Deep Clean Your Washing Machine Agitator

Do you ever notice a lingering smell in your laundry, even after a fresh wash? Or perhaps you see dark spots or residue inside your washing machine? The culprit might be your agitator. This central part of your top-loading washer works hard, but it can also trap dirt, soap scum, and even mold over time. Cleaning the agitator is an important step in maintaining a truly clean washing machine and ensuring your clothes come out fresh every time. I will show you exactly how to clean agitator in washing machine, covering everything from preparation to a sparkling finish.

Takeaway: Restore Your Washer’s Freshness

• Always unplug your washing machine before starting any cleaning.
• Gather necessary tools like screwdrivers, brushes, and cleaning solutions.
• Carefully remove the agitator to access hidden grime and mold.
• Use a baking soda and vinegar paste for effective, natural cleaning.
• Thoroughly clean the agitator and the tub area beneath it.
• Reassemble the agitator and run a cleaning cycle to rinse.

How do you clean an agitator in a washing machine?

To clean an agitator in a washing machine, first unplug the appliance and remove the agitator by unbolting it from the base. Then, scrub the agitator and the inner tub with a mixture of warm water, white vinegar, and baking soda to remove soap scum, mold, and residue. Rinse all components thoroughly before reassembling.

Why Your Washing Machine Agitator Needs Regular Cleaning

Many people clean their washing machine tub. They might run a self-clean cycle or wipe down the dispenser. However, the agitator often goes unnoticed. This component sits in the center of your top-loading washing machine. It moves laundry during the wash cycle. Over time, the agitator can become a hidden magnet for dirt.

Soap scum, fabric softener residue, and lint build up in the agitator’s crevices. This buildup creates a damp environment. Mold and mildew can easily grow there. This growth leads to unpleasant odors inside your washer. These smells can transfer to your clean clothes. A dirty agitator also makes your washing machine less efficient. Residue can interfere with proper water drainage. It can even leave marks on your clothes. This makes regular cleaning essential. I believe a clean agitator makes a big difference in laundry results.

Cleaning your agitator prevents these issues. It ensures your machine runs well. It also keeps your clothes truly clean and fresh. A simple cleaning routine can save you trouble later. It helps your washing machine last longer. This is a vital part of home appliance care.

Essential Tools and Cleaning Supplies for Agitator Cleaning

Before you start, gather everything you need. Having all your supplies ready makes the process smoother. You probably have most of these items already. I always prepare my tools first. This prevents interruptions during the cleaning.

Here is a list of essential tools and supplies:

• Screwdrivers: You will likely need a Phillips head screwdriver. Some agitators might require a flathead or a nut driver. Check your washing machine’s manual for specific tool needs.
• Pliers or Wrench: These tools help loosen stubborn bolts or nuts. Sometimes the agitator cap can be tight.
• Bucket or Container: This is useful for soaking smaller agitator parts. It also holds dirty water during the cleaning process.
• Scrub Brushes: A stiff-bristled brush is great for scrubbing tough grime. An old toothbrush can reach small cracks.
• Microfiber Cloths or Sponges: These are good for wiping surfaces. They help absorb water and apply cleaners.
• Gloves: Protect your hands from cleaning solutions. They also keep your hands clean from the grime.

For cleaning solutions, I recommend these items:

• White Vinegar: This is a natural disinfectant and deodorizer. It cuts through soap scum and mineral deposits. Vinegar is effective against mildew.
• Baking Soda: Baking soda is a gentle abrasive. It helps remove stains and neutralize odors. When mixed with vinegar, it creates a powerful cleaning action.
• Dish Soap: A few drops of dish soap can help break down grease and oils. This is good for heavily soiled areas.
• Warm Water: Warm water helps dissolve cleaning solutions. It makes scrubbing more effective.

You might also consider a dedicated appliance cleaner. These products often target specific washer problems. However, vinegar and baking soda work well for most agitator cleaning tasks. They are safe for your machine and good for the environment. For more general cleaning with these household staples, you can check out our guide on how to clean with vinegar and baking soda.

Safety First: Preparing Your Washing Machine for Cleaning

Safety is the most important step before you begin any deep cleaning. Working with appliances that use electricity and water requires caution. I always make sure to put safety first. Ignoring these steps can lead to electric shock or damage to your machine.

Here are the safety precautions you must take:

• Unplug the Washing Machine: This is the first and most critical step. Locate the power cord and pull it directly from the electrical outlet. Do not just turn off the machine. Unplugging it completely removes all power. This prevents accidental startup during the cleaning process. It protects you from electric shock.
• Turn Off Water Supply (Optional but Recommended): You can also turn off the hot and cold water supply valves. These are usually located behind the washing machine. Turning them off prevents water from accidentally filling the tub. This is especially helpful if you plan to remove the agitator. It stops any unexpected water flow.
• Empty the Washer Tub: Make sure the washing machine tub is completely empty. Remove any clothes or items left inside. If there is water, run a drain/spin cycle to remove it. You want a dry tub to work in.
• Clear the Work Area: Move anything around the washing machine that might get in the way. You need enough space to work comfortably. This includes detergent bottles or laundry baskets.
• Wear Protective Gear: Put on your gloves. This protects your skin from dirt, grime, and cleaning solutions. If you are sensitive to smells, you might also wear a simple mask.

These steps ensure a safe cleaning experience. They protect you and your appliance. Once these safety measures are complete, you are ready to move on. Preparing properly makes the entire cleaning process much easier and safer.

Step-by-Step Guide: Removing the Agitator from Your Top-Loader

Removing the agitator might seem challenging. However, most top-loading washing machines have a straightforward design. I have done this many times. It becomes easier with practice. Follow these steps carefully to remove it without damage.

Here is how you typically remove the agitator:

1. Locate the Agitator Cap: Look at the top of the agitator. There is usually a cap that covers a bolt or screw. This cap might be a simple pop-off cover. It could also twist off. Use a flathead screwdriver or your fingers to gently pry it up or twist it. If it is stubborn, a small amount of force is okay. Be careful not to break the plastic.

2. Unscrew the Agitator Bolt: Once the cap is off, you will see a large bolt or screw. This bolt holds the agitator in place. Use the correct size socket wrench or screwdriver to loosen it. Turn it counter-clockwise. Some bolts are very long. Continue unscrewing until it is completely loose. Keep the bolt in a safe place. You will need it later.

3. Lift the Agitator Out: This part requires a bit of effort. The agitator is often heavy. It might also be stuck due to soap scum buildup.

   • Method 1 (Gentle Wiggle): Grasp the agitator firmly at its base. Wiggle it from side to side while pulling upwards. Apply steady, even pressure.
   • Method 2 (Using Straps/Ropes): If it is very stubborn, you can try looping a sturdy strap or rope underneath the agitator. Use two people, one on each side, to pull upwards evenly. This provides more leverage. Be careful not to damage the inner tub.
   • Method 3 (Warm Water Soak): For extremely stuck agitators, pour some warm water into the tub. Let it sit for 10-15 minutes. This can help loosen any caked-on residue. Then try wiggling it again.

4. Separate Agitator Components (If Applicable): Many agitators come in two parts. There is a lower base and an upper, smaller section. These parts often twist apart. Check if yours does. Separate them to clean both sections thoroughly. More grime can hide between these parts.

Once the agitator is out, you will likely see a surprising amount of gunk. This is normal. It shows why cleaning it is so important. Now you are ready to deep clean it. You might also notice mold inside the machine tub or on other parts. For a comprehensive approach to tackling this common issue, consider our guide on how to clean mold from washing machine.

Deep Cleaning the Agitator and Its Components

With the agitator removed, you can now give it a thorough cleaning. This is where you tackle all that built-up grime, soap scum, and any mold. I find this part very satisfying. Seeing the dirt disappear proves the effort is worth it.

Here is how to deep clean the agitator:

1. Rinse Off Loose Debris: Take the agitator parts to a utility sink or outside. Rinse them with warm water. This removes loose lint, hair, and soft grime. You will get a clearer view of the areas needing more attention.

2. Prepare Your Cleaning Solution:

   • Baking Soda Paste: Mix about half a cup of baking soda with a small amount of warm water. Create a thick paste. This paste is an excellent gentle abrasive.
   • Vinegar Solution: Fill a spray bottle with undiluted white vinegar. Vinegar is a powerful natural disinfectant. It also dissolves mineral deposits.
   • Optional Dish Soap: Add a few drops of dish soap to the baking soda paste for extra degreasing power.

3. Scrub the Agitator Parts:

   • Apply the baking soda paste to all surfaces of the agitator. Pay special attention to the underside, the fins, and any grooves.
   • Use your stiff-bristled scrub brush to scrub vigorously. The paste helps lift grime.
   • For tight spots and small crevices, use an old toothbrush. This tool is perfect for reaching into corners where mold often hides.
   • Spray vinegar onto mold spots. Let it sit for a few minutes. Then scrub again. Vinegar works well to kill mold spores.
   • If your agitator has an internal part that separates, clean both the outer and inner sections. Residue often accumulates between them.
   • Pay close attention to the agitator’s shaft. This part connects to the machine’s base. It often gathers residue.

4. Soak if Necessary: For extremely stubborn buildup, you can soak the agitator parts. Fill a bucket with warm water and a cup or two of white vinegar. You can also add half a cup of baking soda. Submerge the agitator parts and let them soak for 30 minutes to an hour. This helps loosen tough grime. After soaking, re-scrub the parts.

5. Rinse Thoroughly: After scrubbing, rinse all agitator components very well with clean warm water. Make sure no cleaning solution or residue remains. You want them spotless. Dry the parts completely with a clean cloth before reassembling. Excess moisture can lead to new mold growth.

This thorough cleaning ensures your agitator is spotless. It removes all the hidden gunk. You are preparing your machine for cleaner laundry. You might also want to inspect other parts of your machine for cleanliness. For instance, the fabric softener dispenser is another common spot for buildup, and knowing how to clean a softener dispenser in a washing machine can further improve your machine’s overall hygiene.

Cleaning the Washing Machine Tub Underneath the Agitator

Removing the agitator exposes an area of the washing machine tub that usually never sees the light of day. This hidden space is a prime spot for dirt, soap residue, and mold to accumulate. Cleaning this part is just as important as cleaning the agitator itself. I often find this area surprisingly dirty.

Here’s how to clean the tub area underneath where the agitator sits:

1. Inspect the Tub Base: Look closely at the bottom of the washing machine tub. You will likely see dark, slimy residue, mineral deposits, or even visible mold growth. Note the worst areas.
2. Remove Loose Debris: Use a wet/dry vacuum if you have one to suction out any loose debris. This includes lint, small items, or standing water. If not, carefully wipe out as much as you can with paper towels.
3. Apply Cleaning Solution:
   • Baking Soda Paste: Just like with the agitator, apply a thick baking soda paste to the dirty surfaces of the tub base. Focus on areas with heavy grime or mold.
   • Vinegar Spray: Spray undiluted white vinegar directly onto the areas you’ve covered with paste, or onto any other dirty spots. The vinegar will react with the baking soda, creating a fizzing action. This helps lift and loosen stubborn residue.
   • Let it Sit: Allow the cleaning solution to sit for 10-15 minutes. This gives the vinegar and baking soda time to break down the grime.
4. Scrub the Tub Base: Use your stiff-bristled brush to thoroughly scrub the entire exposed tub base. Pay extra attention to the drive shaft where the agitator attaches. This area often has significant buildup. Use your toothbrush for tight spaces.
5. Address Mold and Mildew: If you find significant mold, ensure you scrub it away completely. Vinegar is effective, but for very stubborn mold, you might need a mild bleach solution (diluted, e.g., 1 part bleach to 10 parts water). Apply it, let it sit briefly, then scrub. Always wear gloves and ensure good ventilation when using bleach.
6. Rinse the Tub: Once you have scrubbed all areas, you need to rinse the tub.
   • You can use a spray bottle filled with clean water to rinse down the sides.
   • Alternatively, pour several cups of clean water into the tub.
   • Use a clean cloth or sponge to wipe down all the cleaned surfaces.
   • You may need to run a quick rinse cycle on your washer (without the agitator) to wash away remaining residue and dirty water. If you do this, ensure the power is restored only for the rinse cycle and then unplugged again for reassembly.
7. Wipe Dry: After rinsing, wipe the entire tub base dry with a clean, dry cloth. This prevents new water spots and discourages immediate mold regrowth.

This step is crucial for overall washing machine hygiene. Cleaning this hidden area ensures that no hidden sources of odor or grime remain. When you clean the agitator, you are really giving the entire center of your washer a full refresh. You might also find similar grime in other parts, like the rubber gasket in front-loaders. Understanding how to clean a rubber gasket in a washing machine can further enhance your cleaning knowledge for different washer types.

Reassembling the Agitator and Running a Test Cycle

Once your agitator parts are sparkling clean and dry, it is time to put everything back together. Reassembly is usually the reverse of disassembly. This final step brings your washing machine back to full, fresh function. I always feel a sense of accomplishment at this stage.

Here is how to reassemble the agitator:

1. Reassemble Agitator Components (If Separated): If your agitator came apart into two sections, first put those sections back together. They usually twist and lock. Make sure they are securely joined.
2. Align the Agitator with the Drive Shaft: Carefully lower the clean agitator back into the washing machine tub. Look for the splines (ridges) inside the agitator’s base. Align these splines with the drive shaft coming up from the center of the tub. The agitator should slide down smoothly. Do not force it. If it resists, gently wiggle it and adjust the alignment.
3. Secure the Agitator Bolt: Once the agitator is seated properly, reinsert the large bolt or screw. Use your socket wrench or screwdriver to tighten it. Turn it clockwise until it is snug. Do not overtighten, as this can strip the threads or damage the agitator. It just needs to be firm enough to hold the agitator in place during cycles.
4. Replace the Agitator Cap: Place the agitator cap back onto the top. It should snap or twist securely into place. Ensure it is flush with the agitator’s surface.
5. Reconnect Water and Power: Plug the washing machine back into the electrical outlet. If you turned off the water supply, turn the hot and cold water valves back on.

Now, your washing machine is ready for a test run. This step helps rinse away any remaining cleaning solution. It also verifies that the agitator is correctly installed and working.

1. Run a Self-Clean Cycle (If Available): Many modern washing machines have a self-clean cycle. If yours does, run this cycle. It uses hot water and high agitation to flush out the system.
2. Run a Hot Water Cycle: If your machine does not have a self-clean option, run an empty hot water wash cycle. Use the highest water level setting.
3. Add Cleaning Boosters: For this empty cycle, you can add half a cup of white vinegar to the detergent dispenser. You can also add half a cup of baking soda directly into the tub. This acts as a final rinse and deodorizer. It helps ensure everything is perfectly clean. For more detailed instructions on this method, refer to our guide on how to clean washing machine with baking soda and vinegar.
4. Check for Leaks or Issues: During the cycle, listen for unusual noises. Check around the machine for any leaks. If the agitator makes strange sounds, it might not be seated correctly. Stop the cycle and recheck.
5. Wipe Down the Exterior: After the cycle finishes, leave the washer lid open to air dry. Wipe down the machine’s exterior. Your washing machine is now truly clean inside and out.

Maintaining a Clean Agitator: Prevention Tips

Cleaning your washing machine agitator deeply is a big job. But you can reduce how often you need to do it. Regular maintenance makes a huge difference. I follow these tips to keep my agitator and machine fresh for longer.

Here are simple prevention tips:

• Use the Right Amount of Detergent: More detergent does not mean cleaner clothes. Too much detergent creates excessive suds. These suds can leave behind residue. This residue builds up on the agitator and inside the tub. Read your detergent’s instructions. Use only the recommended amount for your load size.
• Opt for HE (High-Efficiency) Detergent: If you have an HE washing machine, always use HE detergent. These detergents are low-sudsing. They are designed for machines that use less water. Using regular detergent in an HE machine leads to too many suds and residue.
• Clean the Detergent Dispenser Regularly: Detergent and fabric softener dispensers also collect residue. This buildup can make its way into the tub and onto the agitator. Wipe out these dispensers weekly. Some dispensers are removable. If yours is, take it out and wash it thoroughly.
• Leave the Washer Lid Open: After each wash cycle, leave the washing machine lid open for several hours. This allows the interior of the machine to air dry completely. Moisture is the biggest friend of mold and mildew. Air circulation helps prevent their growth.
• Run Monthly Cleaning Cycles: Make it a habit to run an empty cleaning cycle once a month.
  • Use a washing machine cleaner tablet.
  • Or, add two cups of white vinegar to the detergent dispenser. Pour half a cup of baking soda directly into the tub.
  • Run a hot water cycle on the largest load setting. This flushes out residue. It also kills bacteria and odors.
• Wipe Down the Interior after Washes: Quickly wipe down the inside of the drum after your last load of the day. This takes only a minute. It removes any lingering moisture or lint. Pay attention to the top edge of the tub.
• Address Hard Water Issues: If you have hard water, mineral deposits can build up faster. Consider using a water softener product in your wash. You might also need to run cleaning cycles more frequently. White vinegar is excellent for breaking down hard water deposits.

By following these simple maintenance steps, you can prevent most agitator grime. You will keep your washing machine fresh. Your laundry will smell cleaner, and your machine will work better. This proactive approach saves you time and effort in the long run.

Troubleshooting Common Agitator Cleaning Issues

Sometimes, cleaning your agitator does not go exactly as planned. You might face stubborn grime or lingering smells. I have encountered these issues myself. Knowing how to troubleshoot helps you get the best results.

Here are common issues and their solutions:

• Agitator is Stuck and Won’t Come Out:
  • Problem: The agitator is firmly stuck even after unscrewing the bolt.
  • Solution: Soap scum and mineral buildup often glue it in place. Pour a few gallons of very hot water into the tub. Let it sit for 15-30 minutes. The hot water helps dissolve the gunk. Then try wiggling and pulling it again. You can also add a cup of vinegar to the hot water. If it is still stuck, you might need an agitator removal tool. These tools are specialized pullers available online or at appliance parts stores.
• Lingering Mold or Mildew Smell:
  • Problem: You cleaned the agitator, but a musty smell remains.
  • Solution: Mold can hide in other parts of the washing machine.
    • Check the rubber gasket (if your top-loader has one).
    • Clean the detergent and fabric softener dispensers thoroughly.
    • Run several empty hot water cycles with strong cleaning agents. Use a specialized washing machine cleaner, or a mixture of bleach (1 cup) and hot water. Let it agitate, then let it soak for 30 minutes, then complete the cycle. Repeat if needed. Ensure the machine is completely dry after use by leaving the lid open.
    • Also, ensure your drainage hose is not clogged, as standing dirty water can contribute to smells.
• Stubborn Stains or Discoloration:
  • Problem: Even after scrubbing, some areas of the agitator remain discolored or stained.
  • Solution: For plastic parts, apply a paste of baking soda and a little hydrogen peroxide. Let it sit for an hour. Then scrub vigorously. For very dark mold stains, a mild bleach solution (diluted, never mix with vinegar or ammonia!) applied directly with a cloth might be necessary as a last resort. Always rinse thoroughly.
• Agitator Makes Noise After Reassembly:
  • Problem: The agitator grinds or knocks after you put it back.
  • Solution: This usually means the agitator is not seated correctly on the drive shaft. Unplug the machine. Remove the agitator again. Carefully realign it with the splines on the drive shaft. Ensure it slides down smoothly and completely. Re-tighten the bolt. If the noise persists, the drive shaft or agitator might be damaged. You might need professional help.
• Water Doesn’t Drain Properly After Cleaning:
  • Problem: You notice water pooling or draining slowly after cleaning.
  • Solution: During cleaning, some debris might have dislodged and entered the drain pump or filter. Check your washing machine’s drain pump filter. Many machines, especially newer ones, have an accessible filter at the bottom front. Refer to your manual for its location and how to clean it. This helps clear blockages.

Troubleshooting these issues ensures your washing machine works perfectly. It means your cleaning effort pays off. A well-maintained washing machine provides clean, fresh laundry every time.

Frequently Asked Questions About Cleaning Your Agitator

How often should I clean my washing machine agitator?

I recommend cleaning your washing machine agitator thoroughly at least once every six months. If you do a lot of laundry, use a lot of fabric softener, or have hard water, you might need to clean it every three to four months. Regular monthly maintenance cycles (empty hot washes with vinegar or a cleaner) help extend the time between deep cleans.

What causes buildup on the agitator?

Buildup on the agitator is mainly caused by undissolved detergent, fabric softener residue, and lint from clothes. These combine with moisture inside the washer. This creates a sticky environment perfect for mold, mildew, and soap scum to grow. Hard water minerals can also contribute to this residue.

Can I clean the agitator without removing it?

You can clean the visible parts of the agitator without removing it. Use a brush and cleaning solution to scrub accessible surfaces. However, for a truly deep clean, I find it necessary to remove the agitator. Most grime and mold hide underneath it and within its internal components. Removing it lets you reach these hidden areas.

Is it hard to remove an agitator?

Removing an agitator is a relatively simple process for most top-loading washing machines. It usually involves prying off a cap and unscrewing one large bolt. The most challenging part can be wiggling a stuck agitator free due to heavy buildup. With the right tools and patience, most homeowners can do it themselves.

What if my agitator still smells after cleaning?

If your agitator still smells after cleaning, the odor source might be elsewhere in the machine. Check for mold in the detergent dispenser, the drum itself, or the drain hose. Run several empty hot wash cycles using strong cleaning agents like bleach (never mix with vinegar) or a dedicated washing machine cleaner. Ensure the washer completely air dries after each use by leaving the lid open.

Are there agitator-less washing machines?

Yes, there are washing machines without agitators. These are typically called “High-Efficiency (HE) top-loaders” or “front-loaders.” Instead of a central agitator, they use impellers or tumbling actions to clean clothes. While they don’t have an agitator to clean, they still need regular cleaning for their tubs, dispensers, and gaskets
