⚠️ Safety Tips for Deep Clean a Top-Load Washing Machine (Agitator & Tub)

•If using bleach, ensure the area is ventilated and do not mix bleach with any other cleaners (like vinegar or ammonia)
•Unplug the washer if you plan to remove the agitator or any parts for cleaning to avoid any chance of it turning on
•Be careful of metal pieces or sharp edges if reaching under the agitator or around the tub

# Deep Clean a Top-Load Washing Machine (Agitator & Tub)

Top-load washers can also accumulate detergent residue and odors, especially under the agitator and along the top rim of the tub. Performing a deep clean will remove build-up and keep your washer smelling clean.

## When to Clean a Top-Loader

- If you notice a musty smell when you open the washer lid
- Visible grime or scum on the agitator or tub walls
- After washing particularly dirty loads (to prevent lingering dirt)

## Step-by-Step Instructions: Deep-Clean a Top-Load Washer

We’ll use hot water, bleach (or vinegar as an alternative), and a soak to get your top-loader pristine.

Step-by-Step Guide for Deep Clean a Top-Load Washing Machine (Agitator & Tub)

Fill with Hot Water and Add Cleaner

Set your washer to the largest load size and hottest water. As it fills, add 2 cups of chlorine bleach (without any clothes, of course). Once filled, pause the cycle to let the bleach water sit. Soak for about 1 hour - this will kill mold and loosen soap scum.

💡

If you prefer not to use bleach, use 4 cups of white vinegar instead and soak. Do not combine bleach and vinegar.

Agitate Briefly and Soak

After a 1-hour soak, close the lid and let the washer run for a few minutes to stir the solution (or manually advance it to agitate for a minute). Then pause again and allow another 30 minutes of soaking. This ensures the solution reaches all areas.

💡

This intermittent agitation helps slosh the cleaning solution up into hard-to-reach areas, like under the rim and around the agitator.

Complete the Cycle

Resume the cycle and let it run through completely, including the rinse and spin. The bleach or vinegar water will drain away, taking loosened residue with it. Once done, your washer tub should smell cleaner already.

💡

If your washer has a second rinse option, use it to ensure all bleach or vinegar is fully rinsed out.

Clean the Agitator and Rim

Open the lid and inspect the agitator (the central post). If it has a removable cap, take it off and clean inside it. Wipe the agitator’s surface with a cloth and vinegar or a baking soda paste for any spots. Also wipe around the top rim of the tub, where suds and dirt accumulate.

⚠️

If the agitator is extremely dirty beneath or you suspect buildup underneath, you may need to remove it (typically by unscrewing a bolt under the cap). Only do this if comfortable and you have instructions; otherwise, clean what you can reach and consider a professional for deeper cleaning.

Run a Second Cycle with Baking Soda (Optional)

For extra freshness, run another empty hot water cycle, this time adding 1/2 cup of baking soda. This helps neutralize any remaining odors and scrub away lingering grime. Let it run fully.

💡

Baking soda is gentle and will not harm your washer; it’s a good final touch for deodorizing.

Wipe Dry and Air Out

Use an old towel to wipe out any remaining moisture from the tub and agitator. Leave the lid open for a few hours so the washer can fully dry out. This prevents new mold from taking hold.

💡

Keep the lid open between uses to allow air circulation. This is one of the best ways to prevent odors from returning.
