The drum smells weird. You know it does. It’s that musty, wet-sock odor that haunts every household that ignores appliance maintenance.
Fixing it isn’t rocket science. You just need the right tool. We tested them. Some work. Some don’t.
The Top Pick
Affresh tablets. They are the gold standard.
Why? They just work.
Affresh is owned by Whirlpool. They make the machines, so they know exactly what builds up inside them. The tablets dissolve completely. They clean the drum. They handle internal parts. You drop one in, run a hot cycle, and walk away.
- EPA Safer Choice certified
- Septic safe
- Cheap. Roughly $2 per tablet
It leaves a bit of film behind, yes. You wipe that out with a damp cloth. Easy fix. But the smell? Gone. One single tablet killed the odor in my own machine. No scrubbing required.
Specs:
* Form: Tablet
* Pack size: 3 or 6
* Scent: None
The Budget Choice
Like Affresh but want to save money? Get Active.
Cost less than half as much. If you buy in bulk, it gets even cheaper. The formula is enzymatic. That means it eats organic grime. Soap scum? Gone. Bio-films? Eaten. Fresh mold? Destroyed.
Old stains might stay. You’ll still need to manually wipe the rubber gasket on front-loaders. Tablets rarely reach the deep folds there.
Also, you usually have to buy online. Grocery stores rarely stock Active.
Specs:
* Form: Tablet
* Pack size: 24
* Scent: None
The Fresh Option
Molly’s Suds offers jumbo tablets that smell like lemon.
Big ones. You use one every thirty loads, or roughly once a month. The ingredients are simple. Essential oils provide the scent. No synthetic junk.
It dissolves slowly. No powdery mess. It lifts residue while making the drum smell like a citrus grove. Septic-safe. Works in all machine types.
The only downside? The box is small. Six or ten tablets max.
Specs:
* Form: Tablet
* Pack size: 6 or 10
* Scent: Lemon
The Powder Powerhouse
OxiClean knows stain removal. Their machine cleaner is just an extension of that skill set.
Powder. Not a tablet. You dump the pre-measured packet into the drum. Run the cycle. Done.
“The smell is intense,” noted editor Emma Ashe. “Not bad. Just strong.”
It works well on odor and residue. It comes in single-use pouches, which makes dosing impossible to mess up.
You might find residue at the end. Wipe the drum dry before your next load.
Specs:
* Form: Powder
* Pack size: 4 pouches
* Scent: Not listed
The DIY Vinegar
Who says you need a branded tablet? Vinegar does the job.
But not just any vinegar. You need 6% acidity. Aunt Fannie’s Cleaning Vinegar hits that mark. Most store-bought white vinegar is only 5%. That extra potency breaks down buildup faster.
Mix it with baking soda for full effect. It is eco-friendly. It is cheap. And it smells… pungent.
You can buy scented versions (lemon exists). But the classic clean smell is sharp. Don’t eat it. This is strictly for cleaning.
Specs:
* Form: Liquid
* Pack size: 32 oz
* Scent: None
The Essential Sponge
You can automate 90% of the clean. You need to handle the 10% manually.
Enter Scrub Daddy.
The flexible foam sponge. It’s yellow. It changes texture based on water temperature. Cold water makes it stiff for scrubbing grime. Hot water makes it soft for gentle wiping.
This specific version smells like lemon. It lasts weeks, maybe eight. It doesn’t scratch finishes. Keep one in the laundry room. It helps lift the gunk that chemicals miss in the crevices.
Specs:
* Form: Sponge
* Pack size: 1
* Scent: Lemon
The Gasket Saver
Mold hides in the rubber door seal. Tablets won’t touch it. Powder won’t touch it.
Use Active’s Mold Stain Remover Gel.
Squeeze it into the grooves. Let it sit for three to five hours. Wipe it off.
It hardens as it dries, making it easier to scoop away dead mold. Do not run this while washing clothes. Do not mix it with other cleaners during the cycle. It’s for targeted strikes only.
Use it on shower caulk too. Or fridge seals. A 7-ounce bottle lasts about a year if used sparingly.
Specs:
* Form: Gel
* Pack size: 7 oz
* Scent: Unscented
The Final Say
If you want set-it-and-forget-it: Affresh.
If you want to save money: Active.
If you hate powders: Avoid OxiClean.
Check your septic system requirements. Most of these are safe, but read the label. Septic damage is expensive. Smelly repairs are not a hobby anyone wants.
Front-loaders need more frequent cleaning than top-loaders. Why? Water stays trapped in that gasket longer.
How often should you clean? Monthly is good. If it smells, clean it sooner.
You need supplies. Microfiber cloths for residue. An old toothbrush for tight spots. Maybe a spray bottle for vinegar mixes.
Keep it simple. Keep it regular.
