I Ran My Washing Machine’s Drum Clean Cycle with 2 Cups of White Vinegar Every Week for 3 Weeks — Here’s What Happened
I Ran My Washing Machine’s Drum Clean Cycle with 2 Cups of White Vinegar Every Week for 3 Weeks — Here’s What Happened
There comes a moment in every household when you realize that your trusted appliances need a little more TLC than regular use alone can provide.
For me, that moment came when I started noticing a musty odor coming from my washing machine. It wasn’t overpowering, but it was persistent enough to make me wonder whether my clothes were actually coming out as clean and fresh as they should.
With summer approaching and laundry loads increasing, I decided it was time to give my washing machine some extra attention.
That’s when I came across the idea of using white vinegar during the washing machine’s drum clean cycle. Because vinegar is mildly acidic, many people use it as a natural way to help dissolve mineral deposits, soap residue, and odors.
So, for three weeks in June, I decided to run my machine’s drum clean cycle once a week using two cups of white vinegar.
Here’s exactly what happened.
1. Why I Turned to Vinegar and the Drum Clean Cycle in June
June seemed like the perfect time to begin this experiment.
As the weather became warmer, I found myself washing more sweaty clothes, towels, sportswear, outdoor clothing, and other items that can leave behind oils, odors, and detergent residue.
Over time, washing machines can accumulate buildup in places that are easy to overlook, including:
The drum
The rubber door gasket
The detergent drawer
The drain area
Internal water pathways
Even when the inside of a washing machine appears clean, residue can still accumulate in damp, hidden areas.
White vinegar seemed like a simple solution. Its acetic acid can help loosen certain mineral deposits and some types of residue. I also liked the fact that it was inexpensive and already available in my home.
My washing machine also had a dedicated Drum Clean or Tub Clean cycle. This cycle is designed to clean the interior of the machine using a specialized program that may involve higher water levels, longer washing times, or higher temperatures, depending on the model.
My goal was simple:
Could a weekly vinegar cleaning routine help reduce the odor and make my washing machine feel fresher?
2. What My Washing Machine Looked and Smelled Like Before
Before beginning the routine, the washing machine looked relatively clean at first glance.
However, there were several signs that it needed more attention.
The drum had lost some of its fresh, clean smell and had developed a slightly dull appearance. The most noticeable problem was a faint musty odor that became more obvious when I opened the door after a wash cycle.
The rubber gasket around the door was another concern.
It felt slightly slimy in places, and I noticed a few dark marks tucked into the folds. These areas are particularly easy to overlook because water and moisture can remain trapped inside the gasket.
The detergent drawer also contained a layer of old detergent residue. Although I regularly wiped the visible parts, there was still some buildup in the corners and around the compartments.
Nothing looked disastrous, but the machine clearly wasn’t as fresh as it should have been.
3. How I Actually Ran the Weekly Vinegar Drum Clean Routine
I kept the process simple.
Before starting the cleaning cycle, I removed any clothes from the washing machine.
Then I poured approximately two cups of plain white vinegar into the empty drum and started the machine’s dedicated drum-cleaning cycle.
I did not add laundry detergent, fabric softener, or clothing.
The entire purpose of the cycle was to clean the machine itself.
After the cycle finished, I opened the door and allowed the inside of the washing machine to air out.
I also wiped the rubber gasket with a clean cloth and cleaned out the detergent drawer separately.
I repeated the process once a week for three consecutive weeks.
My weekly routine looked like this:
Empty the washing machine completely.
Inspect the rubber gasket for residue or trapped debris.
Add two cups of white vinegar to the empty drum.
Run the dedicated Drum Clean or Tub Clean cycle.
Leave the door open afterward so the interior could dry.
Wipe away any remaining moisture around the gasket.
Clean the detergent drawer separately.
This last step was important because a drum-cleaning cycle doesn’t necessarily clean every part of the machine equally.
Week One: The First Noticeable Difference
After the first cleaning cycle, I immediately noticed a difference in the smell.
The musty odor wasn’t completely gone, but it was significantly less noticeable.
When I opened the door, the machine smelled cleaner and fresher than it had before.
I also noticed a small amount of residue around the rubber gasket that was easier to wipe away after the cleaning cycle.
The drum itself looked brighter, although I wouldn’t describe the difference as dramatic.
The biggest improvement was the smell.
For the first time in a while, I could open the washing machine without immediately noticing that slightly damp, stale odor.
I also began leaving the door slightly open after every regular wash. This allowed the remaining moisture to evaporate instead of remaining trapped inside the machine.
Week Two: The Musty Odor Became Much Less Noticeable
By the second week, the difference was more obvious.
I repeated the same process with two cups of white vinegar and ran the drum-cleaning cycle.
This time, the smell was already considerably better before I even started the cleaning cycle.
After the second treatment, the machine smelled noticeably fresher.
The rubber gasket also seemed easier to clean. There was less slimy residue, and the dark marks I had noticed previously appeared less prominent after regular wiping.
Another change I noticed was that freshly washed towels seemed to smell cleaner.
Previously, towels sometimes developed a slightly stale smell if they remained damp for too long.
After improving the washing machine-cleaning routine and making sure the towels were removed promptly, that problem seemed to improve.
However, I want to emphasize that vinegar was only one part of the solution.
I also began paying more attention to:
Not overloading the machine
Removing laundry immediately after the cycle ended
Leaving the door open
Cleaning the detergent drawer
Wiping the rubber gasket regularly
All of these habits can make a difference.
Week Three: The Washing Machine Felt Fresher Overall
By the third week, the transformation was most noticeable.
The washing machine no longer had the persistent musty smell that had originally motivated me to start the experiment.
The inside of the drum smelled neutral and clean.
The rubber gasket looked better, although I still had to manually wipe it because a cleaning cycle cannot replace physical cleaning of areas where dirt has accumulated.
The detergent drawer also looked cleaner after I removed it and washed it separately.
The biggest improvement was that the entire machine felt fresher.
I no longer felt that I was washing clothes in a machine that was simply hiding old detergent residue and moisture.
4. What Happened to My Laundry?
The most important question was whether the cleaning routine actually affected my clothes.
In my experience, laundry seemed to come out fresher.
The difference was especially noticeable with:
Towels
Bedding
Workout clothes
Heavily worn clothing
Items that had previously developed a musty smell
The clothes did not suddenly smell strongly of vinegar.
In fact, I didn’t notice a vinegar odor after the cleaning cycle had finished.
The washing machine itself simply seemed fresher, which made the entire laundry routine feel cleaner.
5. The Biggest Change Was Not the Vinegar — It Was the New Routine
One of the most important things I learned during this experiment was that the vinegar alone probably wasn’t responsible for every improvement.
The three-week routine encouraged me to start taking better care of the washing machine overall.
I began:
Leaving the door open
After every wash, I left the door open for a while to allow the drum and gasket to dry.
Removing clothes promptly
Wet laundry left inside a closed washing machine can quickly develop an unpleasant smell.
Cleaning the rubber gasket
I started wiping the folds of the rubber seal more frequently.
Cleaning the detergent drawer
Old detergent and fabric softener residue can build up in the drawer and contribute to unpleasant odors.
Avoiding excessive detergent
More detergent does not necessarily mean cleaner clothes. Excess detergent can leave residue behind, especially when the machine is overloaded or used with low-temperature cycles.
6. What I Would Do Differently Next Time
Although the three-week routine worked well for me, I would not necessarily continue using two cups of vinegar every single week indefinitely.
A weekly deep-cleaning schedule may be more frequent than necessary for many households.
The ideal frequency can depend on:
How often you use your washing machine
Whether you use cold-water cycles
The hardness of your water
How much detergent you use
Whether you frequently wash heavily soiled clothing
The manufacturer’s recommendations
For regular maintenance, many people may find that a monthly cleaning routine is sufficient, while households with heavy use may need more frequent attention.
The most important thing is to follow your washing machine manufacturer’s instructions.
7. An Important Safety Note About Vinegar and Washing Machines
Although white vinegar is commonly used as a household cleaning ingredient, it should never be mixed with chlorine bleach.
Mixing vinegar with bleach can create dangerous chlorine gas.
If you use different cleaning products, always use them separately and follow the product labels.
It’s also important to check your washing machine’s owner’s manual before using vinegar regularly.
Some manufacturers advise against repeated use of acidic products because they may affect certain rubber components or seals over time.
If your manufacturer recommends a specific washing-machine cleaner, that recommendation should take priority.
8. The Final Results After Three Weeks
After three consecutive weekly drum-cleaning cycles, the results were clear.
Before the routine:
The washing machine had a faint musty odor.
The rubber gasket felt slightly slimy.
There was detergent residue in the drawer.
The drum didn’t smell particularly fresh.
Some towels occasionally developed a stale smell.
After three weeks:
The musty odor was significantly reduced.
The drum smelled fresher.
The rubber gasket was easier to maintain.
The detergent drawer was cleaner after being washed separately.
Laundry seemed fresher overall.
The washing machine felt cleaner and better maintained.
The most surprising part was how quickly a simple maintenance routine changed the way the machine smelled.
Final Thoughts
After using two cups of white vinegar during my washing machine’s drum-cleaning cycle once a week for three weeks, I noticed a clear improvement in the freshness of the machine.
The musty smell that had been bothering me was greatly reduced, and the washing machine felt cleaner overall.
However, the biggest lesson was that cleaning the drum alone isn’t enough.
A washing machine needs regular attention in several areas, especially the rubber gasket, detergent drawer, and areas where moisture can remain trapped.
For me, the combination of occasional deep cleaning, better ventilation, regular wiping, and removing laundry promptly made the biggest difference.
If your washing machine has started developing a slightly stale or musty smell, it may be time to give it some extra care.
Just remember to check your machine’s manual first, never mix vinegar with bleach, and don’t rely on vinegar alone to remove heavy mold or deeply established buildup.
Sometimes, the simplest household maintenance routines can make the biggest difference.
