Have you ever opened your washing machine and noticed a musty smell?
It’s frustrating when the appliance that’s supposed to make your clothes smell fresh starts developing an unpleasant odor of its own.
Over time, detergent residue, fabric softener, hard-water minerals, and moisture can build up inside the detergent drawer, rubber seals, and other parts of the machine. That buildup can leave your washer smelling less than fresh.
Why Does a Washing Machine Start to Smell?
Your washing machine cleans your clothes, but it doesn’t automatically clean itself.
Every wash can leave behind small amounts of detergent and fabric softener. Add moisture and minerals from the water, and buildup can gradually develop in places that aren’t always easy to see.
The detergent drawer and rubber door seal are particularly easy to overlook.
If the machine stays damp between washes, those areas can become a source of unpleasant smells.
The Two-Lemon Cleaning Trick
The idea behind this simple hack is surprisingly straightforward: use fresh lemons during an empty hot wash to help freshen the machine.
You’ll need:
- 2 fresh lemons
- A clean cloth
That’s it.
Step 1: Get Two Lemons
Regular lemons work perfectly well.
They don’t need to look perfect, so this can also be a convenient way to use lemons that are slightly past their prime.
Step 2: Cut the Lemons in Half
Cut both lemons in half.
This exposes more of the fruit and allows the juice and natural citrus oils to be released more easily.
Step 3: Place Them in the Detergent Compartment
The original hack recommends placing the lemon halves directly into the washing machine’s detergent drawer.
This area can collect detergent residue, making it one of the places where buildup can accumulate.
Step 4: Run an Empty Hot Cycle
Run the washing machine without any clothes inside using the hottest cycle available.
As the water moves through the machine, the lemon juice and citrus oils are released, helping freshen the detergent compartment and loosen some residue.
Once the cycle is finished, remove the lemon pieces and wipe the detergent drawer with a clean cloth if necessary.
Don’t Forget the Rubber Seal
The detergent drawer isn’t the only place worth checking.
If you have a front-loading washing machine, take a look inside the rubber door seal.
Moisture, lint, hair, and detergent residue can collect there.
After running the cleaning cycle, wipe the seal carefully with a clean, damp cloth.
If you can see visible mold or heavy buildup, don’t rely on lemons alone. Use a cleaner that’s appropriate for your machine and follow the manufacturer’s cleaning instructions.
Lemon Can Help Freshen—but It’s Not Magic
It’s important to keep expectations realistic.
The lemon trick can be a simple way to freshen a washing machine and loosen some residue, but it isn’t a substitute for proper appliance maintenance.
If your washer has significant buildup, mold, drainage problems, or a persistent odor, you’ll need to investigate the underlying problem rather than simply adding more lemons.
And before using any DIY cleaning method, check your washing machine manufacturer’s instructions.
How to Keep Your Washing Machine Fresher
A little regular maintenance can make a big difference.
Leave the Door Open
After a wash, leave the door slightly open when it’s safe to do so.
This allows the interior to dry instead of trapping moisture inside.
Clean the Detergent Drawer
Remove the drawer periodically and rinse away accumulated detergent and fabric softener.
Wipe the Rubber Seal
Run a cloth around the door gasket regularly, especially if you notice water or debris collecting there.
Don’t Use Excess Detergent
More detergent doesn’t necessarily mean cleaner clothes.
Using too much can leave additional residue behind, which may contribute to buildup over time.
One Important Safety Reminder
Never mix lemon juice with bleach or other cleaning chemicals.
If you’re using a commercial washing-machine cleaner, follow its instructions and don’t combine it with homemade cleaning ingredients.
When in doubt, stick to the manufacturer’s recommended cleaning method.
Final Thoughts
A washing machine can gradually develop unpleasant odors even though it’s constantly being used to clean clothes.
Detergent residue, minerals, and moisture can accumulate in hidden areas and leave the machine smelling musty.
The two-lemon method is a simple DIY trick: cut two lemons in half, place them in the detergent compartment, run an empty hot cycle, and wipe the drawer afterward.
It’s an easy little maintenance idea to try when your washer needs freshening—but regular cleaning of the drawer, rubber seal, and other machine components is still the best way to keep your appliance in good condition.
Sometimes, two ordinary lemons are all you need for a fresher-smelling laundry room.
