A top-load washing machine can look clean at first glance, but the agitator and rim often collect the most hidden buildup. These areas come in contact with detergent, fabric softener, lint, hard water minerals, and laundry soil during regular wash cycles. Over time, that leftover residue can settle around the agitator base, under the rim, inside the inner lip, and along the upper drum area.
If you use your washer often, especially for towels, bedding, kids’ clothes, workwear, or heavily used laundry, cleaning these spots should be part of your regular washer care routine. The good news is that you do not need a complicated process. With a simple manual cleaning routine and a quality washing machine cleaner like True Fresh Washing Machine Cleaner Tablets, you can help keep your top-load washer cleaner inside and out.
This guide explains how to clean the agitator and rim of a top-load washing machine step by step, what areas to focus on, and how washer cleaner tablets can support deeper routine maintenance.
Why Top-Load Washers Collect Buildup Around the Agitator
The agitator is one of the busiest parts of a traditional top-load washer. It moves clothes through the water and helps create washing action. Because it sits in the center of the drum, residue can collect around its base, grooves, and edges.
The washer rim is another common buildup area. Every time the washer fills, spins, drains, and splashes, moisture and residue can reach the rim and inner lip. If these areas are not wiped regularly, they may start to feel sticky, rough, or grimy.
Common causes of buildup include:
-
Too much detergent
-
Fabric softener residue
-
Hard water mineral deposits
-
Lint and laundry soil
-
Frequent cold-water washing
-
Heavy laundry loads
-
Leaving the lid closed after use
These issues do not mean your washer is broken. They simply mean your machine needs regular cleaning, especially in the areas that are easy to overlook.
Common Signs Your Agitator and Washer Rim Need Cleaning
Your top-load washer may need cleaning if you notice any of these signs:
-
Sticky residue around the agitator
-
Dark or gray buildup near the rim
-
White chalky marks from hard water
-
Soap scum around the drum
-
Small flakes appearing during wash cycles
-
Clothes not feeling fully fresh after washing
-
A stale smell coming from inside the washer
-
Grime collecting under the lid or around the inner lip
The agitator and rim are easy to ignore because they are not always in direct view. But once buildup starts forming, it can continue collecting with every load. A simple cleaning routine can help prevent that from becoming a bigger issue.

Step-by-Step Guide: How to Clean the Agitator of a Top-Load Washing Machine
1. Empty the Washer
Before starting, make sure the washer is completely empty. Remove clothes, towels, or any loose items from the drum.
Cleaning should always be done with an empty washer so you can properly reach the agitator, rim, and drum area.
2. Wipe the Outside of the Agitator
Dip a soft cloth in warm soapy water and wipe the full surface of the agitator. Focus on the grooves, ridges, and raised areas where detergent residue and grime can collect.
If your agitator has a fabric softener dispenser on top, remove it if your washer model allows it. Wash it separately with warm water and mild soap, then dry it before placing it back.
3. Scrub Around the Agitator Base
The base of the agitator is one of the most important areas to clean. Buildup often settles where the agitator meets the drum.
Use a soft brush or toothbrush to gently clean around the bottom edge. Move slowly around the full circle. If you see residue, loosen it with the brush and wipe it away with a damp cloth.
4. Clean Grooves and Tight Spots
Some agitators have small grooves, lines, or textured areas. Use cotton swabs or a small brush to clean these tight spaces.
Do not force anything into areas that are not designed to be opened. The goal is to clean visible and reachable spaces without damaging the machine.
5. Wipe Again with Clean Water
After scrubbing, wipe the agitator with a clean damp cloth to remove loosened residue and soap. Then dry the area with a towel.
This helps prevent leftover cleaning solution from sitting on the surface.
Step-by-Step Guide: How to Clean the Rim and Inner Lip of a Top-Load Washer
1. Open the Lid Fully
Open the washer lid and inspect the top rim, inner lip, and area just under the lid. These spots often collect splashed detergent, dust, lint, and residue.
2. Wipe the Upper Rim
Use a damp microfiber cloth with warm soapy water to wipe around the full washer rim. Pay attention to corners and edges.
If the rim feels sticky, let the damp cloth sit on the area for a few minutes, then wipe again.
3. Clean Under the Inner Lip
The inner lip is the hidden edge just inside the washer opening. This area can collect residue because it is not always reached during normal cleaning cycles.
Wrap a damp cloth around your fingers and wipe under the lip carefully. For narrow spaces, use a cotton swab or soft brush.
4. Clean Around the Lid Hinges
The lid hinge area can collect dust and splashes over time. Wipe around the hinges and back corners gently.
Do not pour water directly into hinge areas or control panels. Use a damp cloth only.
5. Dry the Rim After Cleaning
After the rim and inner lip are clean, dry them with a towel. Leaving these areas wet can make residue collect faster.

How to Clean Hidden Areas Around the Washer Drum
After cleaning the agitator and rim manually, the next step is to clean the inside of the washer where water reaches during the cycle. This includes the drum, lower tub area, and internal water-contact areas such as hoses, pipes, and filter area depending on the washer design.
This is where a washing machine cleaner tablet can help. Manual cleaning is great for visible areas, but a tablet supports cleaning through the wash cycle.
How True Fresh Washing Machine Cleaner Helps Clean Inside Your Washer
True Fresh Washing Machine Cleaner Tablets are designed for routine washer maintenance. The tablet goes directly into the empty washer drum and dissolves during the cleaning cycle. As the water moves through the washer, the formula helps loosen and wash away detergent residue, grime, soap scum, and hard water buildup from areas where water can reach.
For top-load washers, this is helpful because the agitator and drum area often collect leftover residue from regular laundry use. After you manually clean the rim and visible agitator areas, running a cleaning cycle with True Fresh helps support a more complete washer cleaning routine.
How to Use True Fresh Washing Machine Cleaner Tablets
-
Make sure the washer is empty.
-
Drop one tablet directly into the drum.
-
Run a normal cycle or washer cleaning cycle, if your machine has one.
-
Let the cycle finish completely.
-
Wipe the rim and lid area dry after the cycle.
For regular maintenance, use one tablet monthly or as needed based on your laundry routine. A 25-pack gives you a long-lasting supply for ongoing washer care.
Manual Cleaning vs Washer Cleaner Tablets: Why Both Matter
Manual cleaning and washer cleaner tablets work best together because they focus on different areas.
Manual cleaning helps with visible buildup around:
-
Agitator surface
-
Agitator base
-
Washer rim
-
Inner lip
-
Lid area
-
Corners and grooves
Washer cleaner tablets help clean water-reachable areas during the cycle, such as:
-
Drum
-
Tub area
-
Internal water-contact areas
-
Hoses and pipes
-
Filter area, depending on washer design
If you only wipe the rim and agitator, you may miss residue inside the machine. If you only run a cleaning tablet, you may still need to wipe the rim and tight corners by hand. That is why a complete top-load washing machine cleaning routine should include both.
How Often Should You Clean a Top-Load Washer Agitator and Rim?
For most homes, a simple monthly routine works well. If you do heavy laundry, use fabric softener often, wash pet items, or live in a hard water area, you may want to wipe the rim and agitator more often.
A good routine looks like this:
-
Wipe the rim weekly or every few loads
-
Clean the agitator surface every 2 to 4 weeks
-
Deep clean the agitator base monthly
-
Use a washing machine cleaner tablet once a month
-
Leave the lid open after laundry to let the drum air out
This routine helps reduce residue buildup before it becomes harder to clean.
Mistakes to Avoid When Cleaning a Top-Load Washing Machine
When cleaning your washer, avoid these common mistakes:
Using Too Much Detergent
Extra detergent does not always mean cleaner laundry. Too much detergent can leave behind sticky residue inside the washer.
Forgetting the Rim
Many people clean the drum but forget the rim and inner lip. These areas need regular wiping because they collect splashes and residue.
Ignoring the Agitator Base
The base of the agitator is one of the biggest buildup zones in a top-load washer. Always check this area when cleaning.
Using Harsh Scrubbing Tools
Sharp or rough tools can scratch washer surfaces. Use soft brushes, cloths, and non-scratch sponges.
Closing the Lid Right Away
After laundry or cleaning, leave the lid open for a while. This helps the inside of the washer dry more fully.
Final Thoughts: Keep Your Top-Load Washer Cleaner with a Simple Routine
Cleaning the agitator and rim of a top-load washing machine does not have to be difficult. Start by wiping the visible areas, scrub gently around the agitator base, clean under the rim, and dry the surfaces after cleaning.
Then, complete the routine with True Fresh Washing Machine Cleaner Tablets. Simply drop one tablet into the empty drum, run a cycle, and let the formula help loosen and wash away residue, grime, soap scum, and hard water buildup from water-reachable areas inside your washer.
For a top-load washer that handles regular laundry, a monthly cleaning routine can make a big difference. Manual cleaning handles the areas you can see, while True Fresh helps support the deeper cleaning cycle inside your machine.
Clean the rim. Clean the agitator. Drop in a tablet. Run the cycle. Done.
