If your laundry isn’t smelling as fresh as it should—or your washing machine gives off a musty odor—it’s probably time for a deep clean. But before you reach for harsh chemicals or expensive machine cleaners, there’s a surprisingly simple trick that’s going viral: the lemon and toothpaste hack.
Yes, really. This unusual combo is being praised by home-cleaning pros and DIYers alike for how well it cleans, deodorizes, and revitalizes washing machines—especially front-loaders that tend to trap grime in hard-to-reach places.
Here’s how it works, why it’s effective, and how to try it at home using ingredients you already have.
Why Your Washing Machine Needs Cleaning
Even though washing machines clean your clothes, they don’t clean themselves. Over time, detergent residue, fabric softener, hard water minerals, and even mold can build up inside the drum, seals, and drain hoses.
Common signs your washer needs a refresh:
- Clothes come out smelling musty
- Black spots on rubber seals (mold or mildew)
- Water doesn’t drain fully
- The machine has a sour or damp odor
Ignoring the buildup can lead to inefficient washes, increased wear on clothes, and eventually even mechanical issues.
The Power of Lemon and Toothpaste
So, why lemon and toothpaste?
- Lemon is rich in citric acid, which breaks down limescale, removes soap scum, and kills bacteria. It also leaves a fresh scent.
- Toothpaste (non-gel, preferably white paste) contains mild abrasives and cleaning agents designed to remove stains, whiten, and eliminate bacteria—making it perfect for tough washer buildup.
“Together, lemon and toothpaste act like a multi-surface cleaner—removing dirt, whitening grime, and eliminating odors naturally.”
How to Use the Lemon & Toothpaste Hack
What You’ll Need:
- 1 lemon (cut in half)
- 2 tablespoons of white toothpaste (not gel or charcoal)
- An old toothbrush or sponge
- Optional: A small bowl of warm water for wiping down
Step-by-Step Instructions:
Step 1: Prepare the Lemon Scrubber
- Take half a lemon and apply a generous layer of toothpaste to the cut surface.
Step 2: Scrub the Drum and Rubber Seals
- Use the lemon (toothpaste side down) to scrub the inside of the drum, focusing on:
- The inner surface
- Around the rubber door gasket (where mold hides)
- Detergent drawer area (remove drawer first if possible)
Use circular motions to work the mixture into the grime.
Step 3: Let It Sit
- After scrubbing, let the lemon and toothpaste residue sit for 10–15 minutes to break down buildup and allow the citric acid to disinfect.
Step 4: Wipe Clean
- Use a damp cloth or sponge to wipe down all the areas where you scrubbed. Rinse thoroughly to remove toothpaste residue.
Step 5: Run a Hot Cycle (Optional but Recommended)
- For a final rinse, run an empty cycle on the hottest setting. Add a splash of white vinegar or lemon juice to the drum if desired.
This step flushes out any leftover grime and clears the drain lines.
Bonus Tip: Clean the Detergent Drawer Separately
Pull out the detergent drawer and soak it in warm water mixed with a few drops of lemon juice and a dab of toothpaste. Scrub with a brush and rinse well before reinserting.
How Often Should You Do This?
You don’t need to use the lemon-toothpaste combo every week. For maintenance:
- Do it once a month to keep your washer fresh and clean
- Wipe the door seal dry after every wash
- Leave the door open after washing to prevent mildew buildup
Does It Work for All Types of Washers?
Yes—with a few caveats:
- Front-loaders benefit most, especially around the rubber door seal and detergent drawer.
- Top-loaders can use this method, too—just focus on the agitator, drum, and lid.
- Avoid using on high-end machines with sensitive coatings without checking your manual.
Final Thoughts
You don’t need a specialty cleaner or harsh chemicals to maintain your washing machine. With just a lemon and some toothpaste, you can scrub away buildup, kill bacteria, and leave your washer smelling as clean as your laundry.
“Simple ingredients. Big results. A fresh washer in under 30 minutes.”
So next time your machine starts to smell off or your clothes don’t come out as fresh, skip the overpriced solutions and try the lemon-toothpaste trick instead—it just might surprise you.
