How to Clean Your Washing Machine

I am a seasonal wildlife field biologist, which means my clothes endure some serious wear and tear.

Most summer nights, I arrive home with clothes caked in salt water, dirt, mud, and sticks. Suffice to say, I put my washing machine through the wringer. Since it takes such good care of my extreme laundry needs, I do my best to return the favor.

Even if you aren’t working your machine as hard as mine, regular cleaning and maintenance will improve your washing machine efficiency and keep your clothes fresh and clean.

Here’s my tried-and-true method to clean my washing machine:

Clean the Exterior

Starting with an empty machine, I clean the exterior first. Use a soft microfiber cloth and a mild cleaner. Focus on the high-touch areas like the handle and buttons. Don't forget those easily missed spots like the edges of the door, the top of the agitator, and around the control panel. For sticky laundry detergent residue, use a damp rag and warm water to loosen it. 

Tip: Avoid detergent drips by switching to HeySunday laundry detergent sheets!

Clean the Detergent Dispenser

Once the outside of your machine is clean, start working on the detergent dispenser. That little area is the workhorse of your washing machine, and soap residue, mold, and dirt can build up in it which prevents your detergents from cleaning as well as it should. 

Start by removing the detergent drawer. Soak it in hot water and soap for 10-15 minutes to loosen any buildup. Then, scrub the inside of the drawer with an old toothbrush, dry it off, and put it back in place. If you see any mold, use a mixture of equal parts water and white vinegar to clean it thoroughly.

Clean the Washing Machine Filter

Most front-loading washing machines have a filter access door in the lower front corner. This filter catches everything from coins to hair ties, so cleaning it regularly helps prevent drainage issues.

1. Place an old towel under the access door.
2. Slowly open the filter door - some water may leak out (warning: it may be smelly!)
3. Remove the filter by turning it counterclockwise.
4. Clean filter with warm soapy water.
5. Check for debris in the filter housing and remove anything you see.
6. Replace the filter, ensuring it's properly sealed.
7. Close the access door.

If you have a top-loading washing machine, check your owner's manual for filter location - it's typically under the agitator or along the top rim of the wash basket.

Run a Cleaning Cycle

Modern washing machines have a self-clean cycle, which is the easiest way to clean the interior. Add a store-bought washing machine cleaner or two cups of white vinegar into the drum. Start the self-cleaning cycle. Let it run.If your machine does not have a self-cleaning cycle, choose the longest and hottest cycle. The heat will help break down any soap scum and bacteria inside the drum.

When the cleaning cycle is complete, wipe down the rubber door seal and the inside of the door. Take a few extra minutes to wipe down the drum and any accessible components. This extra step prevents mold and mildew growth.

Air Dry

Leave the door completely open to let the washing machine air dry. This prevents mold and mildew from forming. I like to leave the door of my washing machine slightly ajar when it is not in use for this same reason. 

Monthly Maintenance Tips

Each month, make sure you run an empty hot water or cleaning cycle to prevent buildup. To prevent mold, wipe the door seal and keep the washing machine door open between uses. 

Keep an eye out for the following signs that your machine needs cleaning: musty odors, residue on clothes, and longer drain times.

Conclusion

Cleaning a washing machine might sound intimidating, but these simple steps make a big difference in your machine's performance. Make it part of your monthly cleaning routine, and you'll be rewarded with fresher clothes and a longer-lasting appliance - even if your laundry gets as dirty as mine!
