Have you ever noticed a strange smell coming from your washing machine? Or perhaps your clothes do not feel as clean as they should? A dirty washer agitator might be the hidden culprit. This central component in top-load washing machines does much of the work to move your clothes during a wash cycle. Over time, soap scum, lint, and mildew can build up on and inside the agitator.

Cleaning your washer agitator improves its performance. It also helps your clothes get truly clean. Neglecting this task leads to unpleasant odors and dirty laundry. I will guide you through the process of cleaning your washer agitator today. We will cover why it matters, what you need, and a step-by-step cleaning method. You will also learn how to keep it clean in the future.

Why Cleaning Your Washer Agitator Matters

A washing machine works hard to clean our clothes. Yet, sometimes the machine itself needs cleaning. The agitator is a key part of many top-load washers. It spins and moves clothes through water and detergent. This action helps remove dirt from fabrics.

However, over time, the agitator collects debris. This debris includes detergent residue, fabric softener, lint, and even mold. These things stick to the agitator and build up inside it. This buildup creates a breeding ground for bacteria and mildew. You might notice a musty smell in your laundry room. This smell often transfers to your freshly washed clothes.

Cleaning the agitator improves your washer’s efficiency. When the agitator is caked with grime, it cannot move clothes as effectively. This means your clothes might not get as clean as they should. A dirty agitator also makes your washer work harder. This can shorten the lifespan of your appliance. Regular cleaning prevents these issues. It ensures your machine runs smoothly. It also keeps your clothes smelling fresh and looking clean. A clean machine simply works better.

Gathering Your Tools: What You Need for Agitator Cleaning

Before you start cleaning your washer agitator, collect all the necessary tools and cleaning agents. Having everything ready makes the process smoother. You will save time and effort. Most items you need are common household products. I find it helpful to lay everything out beforehand.

Here is a list of what you will need:

Safety Gloves: Protect your hands from cleaning solutions.
Screwdriver or Socket Wrench: You will need this to remove the agitator bolt. The size depends on your washer model. Check your washer manual for specific instructions on how to take apart your washing machine agitator.
Warm Water: For mixing with cleaners and rinsing.
Mild Detergent or All-Purpose Cleaner: Good for general scrubbing.
White Vinegar: An excellent natural cleaner for mold and soap scum. Vinegar is a powerful, natural disinfectant. If you want to learn more about using vinegar for cleaning, check out our guide on how to clean washer with vinegar.
Baking Soda: Works as a gentle abrasive and deodorizer.
Old Toothbrush or Small Brush: For scrubbing tight spots and crevices.
Microfiber Cloths or Sponges: For wiping and drying.
Bucket: To hold water or cleaning solution.
Flashlight: To see inside the agitator post if it is dark.

Make sure your washer is unplugged before you begin. This is a crucial safety step. Having the right tools makes cleaning much easier. It ensures you do a thorough job.

Step-by-Step Guide: How to Remove Your Washer Agitator

Removing the agitator might seem like a difficult task. However, for most top-load washers, it is a straightforward process. Follow these steps carefully to remove it safely. Remember to always consult your washer’s manual for specific instructions. Different brands or models, like an LG top load washer or a Speed Queen, may have slight variations in their agitator removal process.

1. Unplug the Washer

This is the most important safety step. Always disconnect the power supply before working on any appliance. Pull the plug from the wall outlet completely. Do not just turn the washer off. This prevents electric shock.

2. Prepare the Washer Tub

Remove any clothes or items from the washer tub. You need a clear space to work. Dry the inside of the tub with a cloth. This helps you get a better grip.

3. Locate the Agitator Bolt

Most agitators are held in place by a single bolt or cap. This bolt is usually at the very top center of the agitator. Sometimes it is hidden under a cap or a softener dispenser. Pop off any caps or pull out the dispenser to reveal the bolt.

4. Unscrew the Bolt

Use your screwdriver or socket wrench to loosen and remove the bolt. Turn it counter-clockwise. Keep the bolt in a safe place. You will need it for reassembly. If the bolt is difficult to turn, try applying a small amount of penetrating oil. Wait a few minutes for it to work.

5. Remove the Agitator

Once the bolt is out, the agitator should lift straight up. It may be tight due to accumulated grime. If it is stuck, try gently wiggling it from side to side. Pull upward firmly and steadily. Do not force it or twist it too much. This could damage the agitator or the post. If your washer is a newer model without a traditional agitator, such as some GE washing machines (top loader no agitator), this step will not apply. These models have impellers or wash plates instead.

6. Inspect for Buildup

Once the agitator is removed, inspect the underside and inside. You will likely see a significant amount of grime. Take a moment to see where the dirtiest spots are. This helps you target your cleaning efforts.

Deep Cleaning Your Washer Agitator: Methods and Solutions

After successfully removing your washer agitator, it is time for the deep cleaning. This step removes all the accumulated dirt, soap scum, and mildew. You have several effective cleaning options. I like to use a combination of methods for the best results.

Method 1: Soap and Water Scrub

This is the most basic cleaning method. It works well for light buildup.

Prepare a solution: Fill your bucket with warm water. Add a few drops of mild dish soap or all-purpose cleaner.
Scrub the agitator: Dip a sponge or brush into the soapy water. Vigorously scrub the entire agitator, both inside and out. Pay extra attention to any grooves, holes, or areas with visible grime. An old toothbrush helps clean tight spots.
Rinse thoroughly: Rinse the agitator under running water. Make sure all soap residue is gone.

Method 2: Vinegar and Baking Soda Soak

For stubborn grime and odors, a vinegar and baking soda solution works wonders. This method tackles mold and soap scum effectively. It is also a natural option if you prefer to clean washer without Affresh.

Create a paste: In a small bowl, mix baking soda with a little water to form a thick paste.
Apply the paste: Spread the baking soda paste over heavily soiled areas of the agitator. Let it sit for 10-15 minutes. This helps loosen grime.
Soak in vinegar: Fill your bucket with warm water and a generous amount of white vinegar (about 1-2 cups). Submerge the agitator in this solution. Let it soak for 30 minutes to an hour. The vinegar breaks down mineral deposits and mildew.
Scrub and rinse: After soaking, use your brush or sponge to scrub the agitator. The grime should come off more easily. Rinse the agitator thoroughly with clean water.

Method 3: Bleach Solution (Use with Caution)

Bleach is effective for heavy mold or mildew. However, use it with caution and never mix it with vinegar or other cleaners. Bleach can damage some washer parts if used incorrectly or too often.

Dilute bleach: Mix about 1/2 cup of bleach with a gallon of warm water in your bucket.
Soak briefly: Submerge the agitator in the bleach solution for no more than 10-15 minutes. A longer soak can cause damage.
Scrub and rinse: Wearing gloves, scrub the agitator. Rinse it extremely well under running water. Ensure no bleach residue remains. Bleach residue can discolor clothes.

After cleaning, let the agitator air dry completely. This prevents new mildew growth. A dry agitator is ready for reassembly.

Cleaning the Agitator Post: Don’t Forget the Housing

You removed the agitator. Now you see the central post it sits on. This area, often called the agitator housing or shaft, also collects a surprising amount of gunk. Many people overlook this step, but it is crucial for a truly clean washer. The hidden grime here can cause bad smells. It also contributes to detergent buildup.

Look closely at the agitator post. You will likely see soap scum, lint, and even mold. Use a flashlight to see into the depths of the post. This area is often dark and damp. It becomes a perfect breeding ground for mildew.

Here is how to clean the agitator post:

Prepare cleaning solution: Dip a cloth or sponge into your warm, soapy water solution. You can also use a mixture of white vinegar and water. For tough spots, a baking soda paste works well.
Scrub the post: Vigorously scrub the entire length of the agitator post. Reach as far down into the housing as you can. A long-handled brush or an old toothbrush can help with hard-to-reach areas.
Wipe thoroughly: Wipe away all loosened grime and cleaning solution. Use a clean, damp cloth.
Dry completely: It is important to dry the agitator post thoroughly. Use a clean, dry microfiber cloth. This prevents new mold from growing.

Cleaning this area makes a big difference. It removes hidden sources of odor and dirt. It ensures your washing machine is truly clean from top to bottom. A clean post helps the agitator spin freely. It also prevents future buildup.

Reassembling and Testing Your Washer After Cleaning

You have cleaned your agitator and the agitator post. Now it is time to put your washing machine back together. This process is essentially the reverse of disassembly. Make sure both the agitator and the post are completely dry before you start. This prevents any immediate mildew growth.

Here are the steps to reassemble your washer:

1. Place the Agitator Back

Carefully align the agitator with the central post in the washer tub. Slide the agitator down onto the post. It should fit snugly. If it feels stuck, gently twist and wiggle it until it slides all the way down. Do not force it. Ensure it sits flush with the base of the washer drum.

2. Secure the Agitator Bolt

Take the bolt you removed earlier. Insert it into the top center of the agitator. Use your screwdriver or socket wrench to tighten it. Turn it clockwise until it is secure. Do not overtighten, as this could strip the threads or damage the agitator. It just needs to be firm enough to hold the agitator in place during cycles.

3. Replace Any Caps or Dispensers

If your agitator had a cap or a fabric softener dispenser on top, put it back now. Make sure it snaps or screws securely into place.

4. Plug In the Washer

Once everything is back together, plug your washing machine back into the wall outlet.

5. Run a Cleaning Cycle

It is a good idea to run a cleaning cycle after reassembly. This helps rinse away any remaining cleaning solution. It also flushes out any loosened debris that might still be in the tub. You can use a dedicated washer cleaning tablet. Or, run a hot water cycle with two cups of white vinegar or a half cup of baking soda. This final rinse also helps deodorize the machine. This step completes the agitator cleaning for your washing machine.

After the cycle, your washer should smell fresh and be ready for laundry. You will notice a difference in how clean your clothes feel.

Preventative Measures: Keeping Your Agitator Clean Long-Term

Cleaning your washer agitator is not a one-time task. Regular maintenance keeps your machine working its best. It prevents odors and ensures your clothes are truly clean. I follow a few simple habits to keep my agitator, and my whole washer, in top shape.

Here are some preventative measures you can take:

Leave the Lid Open: After each wash cycle, leave the washer lid or door ajar for a few hours. This allows air to circulate inside the drum and around the agitator. It helps the interior dry out. This simple step prevents mold and mildew from growing in the damp environment. It is one of the most effective ways to reduce odors.
Use the Right Amount of Detergent: Using too much detergent creates excess suds. These suds leave behind sticky residue on the agitator and in the tub. This residue attracts dirt and can lead to mold. Always follow the detergent manufacturer’s recommendations. Adjust the amount based on your load size and water hardness.
Run Regular Cleaning Cycles: Perform a monthly cleaning cycle for your entire washing machine. You can use specialized washer cleaners. Or, run a hot water cycle with white vinegar or baking soda. This flushes out buildup from the tub, hoses, and agitator. Consider our guide on how to clean your Whirlpool Cabrio washer filter for a comprehensive approach to washer maintenance beyond the agitator.
Wipe Down the Tub and Agitator: After a particularly dirty load, or once a week, quickly wipe down the inside of the washer tub and the visible parts of the agitator. Use a damp cloth to remove any visible lint or scum. This prevents buildup from becoming severe.
Check Pockets: Always check clothes pockets before washing. Small items like coins, tissues, or even tiny toys can get lodged in the agitator mechanisms. These items can cause damage or create areas for debris to accumulate.
Avoid Overloading: Overloading your washer means clothes cannot move freely. This reduces the agitator’s effectiveness. It also means dirt and detergent residues are not properly rinsed away. This can leave more grime on the agitator.

By adopting these habits, you will significantly reduce the need for deep agitator cleaning. Your washer will stay fresher. Your clothes will come out cleaner.

Troubleshooting Common Agitator Cleaning Issues

Sometimes, you might encounter issues while cleaning your washer agitator. Do not worry. Most problems have simple solutions. I have run into a few tricky situations myself. Here are some common issues and how to handle them.

Stuck Agitator: If your agitator will not lift off the post, it is often due to excessive soap scum or mineral buildup.
- Solution: Pour some white vinegar or a mixture of hot water and liquid dish soap into the tub. Let it sit for a few hours, or even overnight. This can help dissolve the grime holding the agitator. Then, try wiggling it gently while pulling upward. You can also try carefully tapping the base of the agitator with a rubber mallet. This helps break the seal.
Stripped Bolt: If the bolt holding the agitator is stripped, you cannot easily remove it with a screwdriver or wrench.
- Solution: You might need to use a bolt extractor tool. These tools bite into stripped bolts, allowing you to turn them. If you are uncomfortable, call a professional appliance repair technician.
Lingering Odors After Cleaning: You cleaned the agitator, but a musty smell remains.
- Solution: The odor might be from other parts of the washer. Check the washer’s hoses, the drain pump filter, or the area under the tub. Run several hot cleaning cycles with white vinegar or a dedicated washer cleaner. For front-load washers, the gasket is a common source of odor. Learn how to clean a front-load washer gasket if you have one.
Agitator Won’t Spin After Reassembly: This is rare but can happen if the agitator is not properly seated or the bolt is too loose/tight.
- Solution: Unplug the washer again. Remove the agitator and check for any obstructions on the post or inside the agitator itself. Reinstall the agitator, ensuring it slides all the way down. Tighten the bolt firmly but do not overtighten. Test with a small load.
Damage During Removal/Reassembly: If you accidentally chip or crack a part of the agitator.
- Solution: Small chips might not affect performance, but large cracks can. If the damage is significant, the agitator may need replacement. Check your washer’s model number and order a replacement part from the manufacturer or a reputable appliance parts store.

Facing issues can be frustrating. However, with patience and the right approach, you can resolve most cleaning problems. Your washer will soon be back to its clean and efficient self.

FAQ Section

How often should I clean my washer agitator?

You should aim to deep clean your washer agitator every 3-6 months. This schedule depends on how often you use your washing machine. It also depends on the hardness of your water. Regular maintenance, like wiping it down weekly, reduces the need for deep cleaning.

Can I clean my agitator without removing it?

You can clean the visible parts of your agitator without removing it. Use a brush and cleaning solution to scrub the exterior. However, removing the agitator allows you to clean the hidden underside and the agitator post. This is where most of the grime and mildew collect. For a truly deep clean, removal is necessary.

What causes mold on the agitator?

Mold grows on the agitator due to moisture, soap scum, and lint buildup. The inside of a washing machine is often damp and dark. This creates an ideal environment for mold and mildew. Using too much detergent or fabric softener also leaves residue that mold feeds on.

Is it safe to use bleach on my agitator?

Yes, you can use diluted bleach on your agitator, but with caution. Mix a small amount of bleach with water. Soak the agitator for a short time, about 10-15 minutes. Always wear gloves. Rinse the agitator thoroughly afterward. Never mix bleach with other cleaners, especially vinegar, as it creates toxic fumes.

How do I know if my washer has an agitator?

Most top-load washing machines have an agitator. It is the large, finned post or column in the center of the wash tub. If your top-load washer has a flat disc or plate at the bottom of the tub instead of a central column, it is likely an impeller model. These models do not have an agitator.
