Your washing machine handles some seriously dirty work every single day. Muddy jeans, sweaty workout clothes, greasy kitchen towels, it takes on everything without complaint. But here's a question most of us never stop to think about: who's actually cleaning the machine itself?
For most households, the honest answer is nobody. And over time, that becomes a real problem.
Detergent residue, lint, body oils, and hard water minerals gradually settle inside your drum, pipes, filters, and detergent tray. Add trapped moisture into that mix, and you've created the perfect environment for mold and bacteria to quietly grow. That's usually the point when clothes start coming out smelling stale despite a fresh wash, or you notice a persistent odour every time you lift the lid.
The good news is the fix is much simpler than most people expect, and you likely already have everything you need sitting in your kitchen.
How Do You Know It's Time for a Clean?
Your machine tends to give you warning signs well before things get seriously bad. The trick is knowing what to look for.
A musty or sour smell coming from the drum is usually the first clue. You might also notice soap scum building up visibly inside the tub, or clothes that just don't smell clean even after a full wash cycle. Sometimes lint or detergent residue gets left on fabrics, water starts draining more slowly than usual, or the machine vibrates more than it normally does during a spin cycle.
If any of those sound familiar, your machine is overdue for a proper clean.
What You'll Need
The best part about cleaning your washing machine at home is that it doesn't require any special products or expensive equipment. Most of what you need is already in your pantry or cleaning cupboard.
Grab white vinegar, baking soda, an old toothbrush, a soft microfiber cloth, a gentle sponge, and some warm water. That's genuinely all it takes for a thorough clean. For machines that run multiple cycles daily or handle particularly heavy loads, a manufacturer-recommended washing machine cleaner is worth using every few months for a deeper result.
Step 1 — Start With an Empty Machine
Before anything else, make sure the drum is completely empty. Check carefully for stray socks, tissues, coins, or anything else tucked away at the bottom. Small forgotten items can cause bigger problems during a cleaning cycle. Once the drum is clear, switch off the power supply before you begin. It's a simple safety step that's easy to skip but worth doing every time.
Step 2 — Clean the Drum Properly
The drum is where the majority of buildup collects, so this step deserves the most attention. For a top-load washing machine, set the water level to the highest setting and let it fill with hot water. Once it's full, add two cups of white vinegar and half a cup of baking soda directly into the drum, not the detergent tray at this point.
Run a complete wash cycle with nothing else inside. The vinegar works through mineral deposits and breaks down detergent residue that has been building up over weeks or months. The baking soda handles the odour side of things, neutralising the smell rather than just masking it. Once the cycle finishes, check inside the drum. For any stubborn marks or staining that's still visible, a gentle scrub with a soft sponge takes care of it without scratching the surface.
Step 3 — Don't Ignore the Detergent Tray
The detergent dispenser tray is one of the most consistently overlooked parts of the entire machine, and it tends to show it. Pull the tray out carefully and take a proper look inside — most people are surprised by how much hardened detergent and fabric softener residue has built up in the compartment over time.
Soak the tray in warm water for a few minutes to loosen the residue. Then take your old toothbrush and scrub into every corner and crevice. The buildup tends to hide in the back sections and along the edges where water doesn't reach during a normal wash. Once it's clean, dry it thoroughly before sliding it back into place. A blocked detergent tray affects how well the detergent actually disperses during a wash, so keeping it clear makes a practical difference to cleaning results.
Step 4 — Clean the Filter
The lint filter is one of those components that rarely gets attention until something goes wrong. Its job is to catch lint, hair, fabric fibres, and small debris before they cause blockages or end up back on your clothes. When it gets clogged, which happens faster than most people realise, the machine starts draining more slowly, residue appears on washed clothes, and unpleasant smells become more frequent.
Find your lint filter, which is usually located near the bottom of the machine or inside the drum depending on the model, and rinse it thoroughly under running water. It takes about two minutes and makes a noticeable difference to how the machine performs afterwards.
Step 5 - Wipe Down the Outside
The exterior of the machine collects dust, detergent splashes, and general grime over time, particularly around the control panel and along the edges of the lid. A damp microfiber cloth is all you need to go over the control panel, glass lid, body of the machine, and any corners or edges where dust tends to settle.
One thing worth keeping in mind,avoid abrasive cloths or harsh chemical sprays on the outer surface. They can dull the finish or leave scratches on the glass lid over time. A damp cloth with mild soap if needed is more than sufficient.
Step 6 — Pay Attention to the Rubber Seals
If you own a front-loading washing machine, this step is particularly important and often skipped entirely. The rubber gasket that runs around the inside of the door opening is notorious for trapping moisture, hair, detergent residue, and mold in the folds that aren't immediately visible.
Gently pull the rubber seal back and take a look inside. In many cases there's a significant amount of buildup hiding in there. Wipe the entire inner surface with a cloth dampened in a vinegar and water solution, working your way around the full circumference of the seal. Even top-load machines can have hidden corners and gaps where moisture accumulates between washes, so it's worth doing a careful inspection of those areas too.
Step 7 — Finish With a Rinse Cycle
Once all the cleaning is done, run one final cycle using plain water only. This flushes out any remaining vinegar, baking soda, or loosened debris that might still be sitting inside the drum or pipes. When the cycle finishes, leave the lid open and allow the drum to air out and dry completely before running your next load of laundry.
Everyday Habits That Make a Big Difference
Leaving the lid open after every wash is one of the simplest things you can do, it lets moisture evaporate instead of sitting inside and encouraging mold growth. Using the correct amount of detergent matters more than people realise too; excess detergent doesn't improve cleaning, it just leaves more residue behind with every cycle.
Avoid overloading the machine. It reduces how effectively clothes get washed and puts unnecessary strain on the motor over time. Move clothes out promptly after a cycle ends, damp laundry sitting in a closed drum for hours is one of the quickest ways to bring that musty smell back. And where possible, match the wash program to the fabric type. Most modern machines have specific settings for cottons, synthetics, and delicates for a reason.
The Bottom Line
A washing machine that gets looked after simply works better. Clothes come out fresher, the machine runs more efficiently, and you avoid the gradual buildup that quietly shortens its lifespan and affects performance.
It doesn't take much, a monthly drum clean, a quick filter rinse, and a few small daily habits are enough to keep everything running the way it should. Your machine works hard for you every day. A little regular care is the least it deserves in return.
