Cleaning your washing machine is crucial for maintaining fresh laundry and ensuring your clothes and linens remain in excellent condition. Yet, it's a chore that often slips our minds.
While there are many commercial cleaners available, some contain harsh chemicals that may leave behind residues harmful to your fabrics. They can also be quite expensive and detrimental to the environment.
That’s why many experts advocate for DIY washing machine cleaners as a way to save both time and money while ensuring a cleaner wash.
Homemade Washing Machine Cleaner
Here, cleaning professionals share their top three recipes for effective DIY washing machine cleaners, addressing issues from unpleasant odors to stubborn mold stains.
1. Deep Clean with Vinegar and Baking Soda

A straightforward yet powerful cleaner involves using vinegar and baking soda, suggests laundry expert Hyacinth Tucker:
“For effective maintenance, pour two cups of distilled white vinegar into the detergent drawer and add ½ cup of baking soda directly into the drum. Run a hot cycle to eliminate detergent residues and odors,” she advises.
The vinegar's acidity helps dissolve mineral buildup and soap scum, while also deodorizing the machine's interior,” explains Alicia Sokolowski, cleaning expert. “Baking soda serves as a mild abrasive, assisting in loosening grime and neutralizing odors. Together, they clean effectively without harsh chemicals.”
2. Combat Odors with Essential Oils

For a fragrant laundry room, adding essential oils is key, Hyacinth Tucker continues.
“I recommend including two small capfuls of eucalyptus oil before starting a hot water cycle,” she shares. “You can also try vanilla for a sweet scent or lemon for a refreshing clean.”
For stronger aroma, mix ten drops of your chosen oil in a spray bottle with water and spritz the drum after cleaning. Just remember to leave the door ajar after cleaning to prevent musty smells from returning.
3. Tackling Mold Stains with Cream of Tartar or Oxygen Bleach

If set-in stains persist after cleaning, manual intervention may be necessary. To treat stubborn stains on the drum or rubber gasket, Eliana Coca, cleaning expert, recommends using either cream of tartar or oxygen bleach to form a paste:
“For tough stains, mix water with cream of tartar or oxygen bleach to create a paste. Apply it, let it sit, then run a hot wash with two gallons of vinegar. This natural bleaching action removes stains and odors effectively.”
Understanding Common Washing Machine Issues
What Causes Gray Sludge in My Washing Machine?
Gray sludge buildup typically consists of soap scum and leftover detergent that hasn't dissolved properly. This often results from excessive detergent use, overloading the machine, or living in an area with hard water. It's essential to clean this sludge to avoid mold and mildew issues.
What Temperature is Best for Cleaning a Washing Machine?
When cleaning, opt for the hottest water cycle to disinfect your washer. Generally, this means a temperature of around 60 degrees or higher, ensuring no laundry is inside. If your machine has a dedicated cleaning cycle, be sure to utilize it.
Using a DIY washing machine cleaner is effective only if you maintain a regular cleaning schedule. Allowing dirt or mold to accumulate hinders any cleaner's efficacy. To keep your machine in optimal condition, run a cleaning cycle at least once a month.
