Most people clean the drum, wipe the door, and occasionally run a cleaning cycle—but there’s one part of the washing machine that’s often completely forgotten.

The detergent drawer.

It may look harmless, but over time it can become a hidden breeding ground for mold, bacteria, detergent residue, and limescale. If left unchecked, all that buildup can lead to unpleasant odors, reduce your washing machine’s performance, and even leave your freshly washed clothes smelling less than fresh.

Fortunately, cleaning it takes only a few minutes—and many people don’t even realize how easy it is.

Why the Detergent Drawer Gets So Dirty

Every wash leaves behind small amounts of detergent and fabric softener.

Over time, these products combine with moisture, creating a sticky residue inside the drawer and its compartment. This damp environment is ideal for mold and mildew to grow.

Eventually, you may notice:

• Musty smells coming from the machine
• Black mold spots
• Hardened detergent residue
• Reduced water flow through the dispenser
• Clothes that don’t smell as clean as they should

Regular cleaning helps prevent these problems and keeps your washing machine working efficiently.

The Cleaning Trick Many People Never Knew

One household cleaning video recently went viral after a woman shared a discovery that surprised thousands of viewers.

Like many people, she had no idea the detergent drawer could be completely removed.

“I found a little release button and pulled the whole drawer out,” she explained. “What I found behind it was disgusting. There was mold and so much built-up
dirt.”

Judging by the comments, she wasn’t alone.

Many viewers admitted they had owned washing machines for years without realizing the drawer was removable.

How to Clean the Detergent Drawer

Cleaning it is much easier than most people expect.

Step 1: Remove the Drawer

Most washing machines have a small release tab inside the detergent drawer. Press it while gently pulling the drawer outward.

If you’re unsure, check your washing machine’s user manual for the correct removal method.

Step 2: Soak It

Fill a sink or bucket with warm water and add a little dish soap.

Let the drawer soak for 15 to 30 minutes to loosen detergent residue and mold.

Step 3: Scrub Thoroughly

Use an old toothbrush or a small cleaning brush to remove stubborn buildup from all corners and compartments.

Pay special attention to areas where detergent tends to harden.

Step 4: Clean the Drawer Housing

Don’t forget the compartment inside the washing machine.

Use a damp cloth or small brush to remove any hidden residue before sliding the drawer back into place.

Keep Your Whole Washing Machine Fresh

Cleaning the drawer is only one part of washing machine maintenance.

Here are a few additional habits that help prevent odors and mold.

Run a Hot Cleaning Cycle

About twice a year, run an empty wash on the hottest setting your machine allows.

Many people use white vinegar to help dissolve mineral deposits and soap residue, although it’s important to follow your appliance manufacturer’s guidance, as some manufacturers discourage frequent vinegar use because it may affect certain rubber components over time.

If your machine has a dedicated drum-cleaning cycle, that’s often the best option.

Wipe the Door Seal

The rubber seal around the door can trap water, lint, and detergent.

After washing, wipe it dry to prevent mold from developing.

Leave the Door Open

One of the simplest maintenance habits is also one of the most effective.

After each wash, leave the door and detergent drawer slightly open so moisture can evaporate.

A dry machine is much less likely to develop mold and unpleasant odors.

What If Your Washing Machine Still Smells Bad?

Persistent odors can sometimes indicate more than a dirty detergent drawer.

You may need to:

• Clean the drain filter
• Check for clogged hoses
• Remove limescale buildup
• Run a machine cleaner designed for washing machines
• Inspect hidden areas for mold

If unpleasant smells continue despite regular cleaning, it may be worth consulting your appliance manual or contacting a service technician.

The Bottom Line

Your washing machine works hard every week, but it also needs regular care to perform at its best.

A clean detergent drawer helps prevent mold, reduces unpleasant odors, improves detergent flow, and keeps your clothes smelling fresh after every wash.

The best part? It only takes a few minutes, and once you know the drawer comes out, you’ll probably wonder why you didn’t clean it sooner.
