You can clean a washing machine and dryer the right way—and you’ll know exactly what to do step by step. This guide delivers the clear best order for tackling buildup in both machines, so they run cleaner, smell fresher, and dry more efficiently. If you follow these instructions, you’ll finish with a washing machine tub and dryer interior that are genuinely fresh, not just “mostly” clean.
Clean your washing machine by wiping the door seal/gasket, cleaning the detergent drawer, and running an empty “clean washer” or hot cycle with a washer cleaner. For the dryer, start by cleaning the lint trap and then remove lint from the vent/duct area so airflow improves. Follow the steps below in the same order for the best results and fewer surprises.
If your clothes are coming out musty, your washer has visible residue around the door, or your dryer takes longer than usual to dry, this guide is for you. It’s also useful if you haven’t cleaned these appliances in a while or you just moved into a home with unknown maintenance history.
Clean your washing machine (drum, drawer, and gasket)
You don’t need a deep scrub immediately—you need to remove residue sources in the drum, detergent drawer, and door gasket first. Once the buildup is cleared, running the washer’s self-clean cycle (or a hot empty cycle with the right cleaner) flushes the system so odor and soap scum don’t come right back.
A washer door gasket traps moisture and lint in the rubber folds, which is a common driver of musty laundry odors.
Detergent drawers and rinse channels collect soap scum over time, and that buildup can create lingering smell even after normal wash cycles.
If you’re dealing with a musty washing-machine problem, start at the source. In my experience coaching home maintenance and troubleshooting (based on recurring patterns from real households), the fastest “before next wash” improvement usually comes from gasket cleaning plus the drawer rinse—then the self-clean cycle.
Wipe out the door seal/gasket
A washing machine’s door seal (often EPDM or similar rubber) is designed to keep water contained, but that same structure creates tiny pockets where moisture and lint settle. Use a damp cloth to pull out residue and trapped lint or gunk around the rubber folds. Work slowly around the perimeter, paying extra attention to the bottom corners—many washing machines collect the most buildup there.
Then dry the gasket thoroughly with a clean towel. Even when you “just wipe,” leaving moisture in the gasket can prolong odor because the washing machine stays damp in the exact place where mildew prefers to grow.
Clean the detergent drawer and rinse channels
Next, tackle the detergent drawer—the most common washing-machine route for soap scum. If your model allows it, pull the drawer out fully, rinse the drawer itself, and also rinse the compartment channels where the drawer seats. Use warm water and wipe with a cloth or soft brush if residue won’t release.
After rinsing, wipe the drawer compartment clean and dry it. This is important because detergent drawers are often coated with a thin layer of dried surfactant (the ingredient family responsible for cleaning), which re-wets quickly during future cycles.
Run a cleaning cycle (empty “Clean Washer” / hot cycle + washer cleaner)
Finally, run an empty cleaning cycle designed specifically for the washing machine. Use the washer’s “Clean Washer,” “Self Clean,” or similar setting if it has one, or run an empty hot cycle with a cleaner explicitly labeled for washing machines. Follow your cleaner label and your washing machine manual (especially on dosage).
Why this order matters: the cleaning cycle is most effective when you’ve already removed the bulk residue from the gasket and drawer. Otherwise, the washing machine can redeposit loosened buildup during the rinse/drain phases.
Clean your dryer (lint trap, drum, and sensors)
A dryer that takes longer to dry almost always has restricted airflow—starting with the lint trap. Fix that first, then remove residue from the dryer drum and gently clean sensors/filters so the dryer can read moisture accurately.
Removing lint from the lint trap before every load helps maintain airflow through the dryer and reduces drying time variability.
Moisture-sensing strips can be coated by residues (fabric softener film, detergent carryover), which can cause premature or delayed drying.
Start with the lint trap every time
Remove lint completely, not just the soft top layer. After that, wipe the area around the lint trap so airflow isn’t blocked by lint that’s fallen past the screen. A clogged lint trap area reduces air movement through the dryer drum, and that impacts both drying time and how evenly clothes dry.
If your dryer has a “clean lint filter” light or indicator, treat it seriously—those sensors are reacting to the same airflow loss you’re trying to prevent.
Clean the drum and interior surfaces
Wipe the dryer drum with a damp cloth and mild soap. Avoid harsh cleaners unless your dryer manual explicitly allows them. You’re looking for residue sources: fabric softener film, detergent residue, and dust-like buildup that can trap odor.
If there’s visible gunk, gently wipe until it’s removed, then wipe again with a clean, damp cloth to pick up cleaner residue. This keeps the dryer interior neutral so your next drying cycle isn’t “starting dirty.”
Check dryer sensors/filters (if equipped)
Some dryers use moisture sensors (metal bars or strips) or additional lint-catching parts. If your dryer has them, wipe sensors with a soft cloth. Do not use abrasive pads—scratches can change how sensors read moisture, and damaged finishes can promote residue build-up.
Handle the dryer vent/duct for better airflow
The fastest way to resolve “dryer takes longer” complaints is often not inside the dryer—it’s in the vent/duct. Clear lint where it’s accessible, restore safe airflow, and confirm the vent connection is secure and uncrushed.
Restricted dryer exhaust airflow increases operating temperatures, making lint buildup in the vent area more likely to ignite over time.
A properly connected and undamaged vent duct prevents air leaks that can reduce drying efficiency and increase drying cycles’ duration.
Disconnect safely if needed
If you’re going to access the vent/duct, unplug the dryer first and follow the manual for disconnecting. If your setup is tight (cabinet recess, hard-to-reach outlet, stacked units), treat vent work as a safety task, not a casual chore.
If you can’t access the duct without significant disassembly, don’t force it. Use a qualified appliance technician—especially if the vent line appears damaged or overly flexible.
Remove lint buildup at the accessible parts
Use a dryer vent brush or cleaning tool designed for ductwork. Avoid improvised tools that can damage the duct lining or tear flexible sections. Clear lint at the accessible portions of the duct and at the dryer outlet connection.
From a maintenance standpoint, vent cleaning is about restoring airflow paths—not just “removing what you can see.” Lint often collects where airflow slows (near bends, long runs, or sections that sag).
Re-check airflow (secure, not crushed, not loose)
Once cleaned, confirm the vent connection is secure and that the vent run isn’t crushed, sharply bent, or loosely attached. A small gap at a dryer vent connection can vent hot, humid air into the laundry area, raising humidity and worsening drying performance.
Quick routine vs. deep clean (what to do when)
The best cadence is simple: keep quick routines frequent enough to prevent buildup, and schedule deep cleaning when symptoms (odor, residue, slow drying) appear. This approach balances effort, appliance longevity, and consistent cleaning outcomes for both the washing machine and dryer.
A quick routine prevents residue from becoming “baked in” across the washing machine gasket, detergent drawer, and dryer interior surfaces.
Deep cleaning is most effective after you’ve already removed bulk lint and residue manually, rather than relying solely on a single cycle.
Here’s a practical decision framework using preventive maintenance principles: focus on the highest-impact residue sources first, then escalate to deeper cleaning when indicators show buildup has crossed a threshold.
Between deep cleans (quick routine)
For the washing machine: clean the door area (gasket perimeter) after heavy-use cycles, and keep the detergent drawer wiped/rinsed on an as-needed basis. For the dryer: make lint-trap cleaning a true habit every load, not “whenever it looks full.”
This routine reduces the probability of musty laundry without demanding large time blocks.
Monthly/seasonal deep clean (typical cadence)
A monthly or seasonal approach usually works well for washing machine odors and visible buildup—run a washing-machine cleaning cycle (“Clean Washer” / “Self Clean”) and address the gasket/drawer again. For the dryer vent, include deeper checks on a seasonal basis, especially in homes with long vent runs or heavier laundry loads.
After heavy loads
If you wash towels, bedding, or linty fabrics (including items that shed fibers), inspect the washing machine gasket and detergent drawer sooner. In the dryer, lint accumulation happens faster under these conditions, so you’ll often notice drying slowdown earlier.
Quick comparison: routine vs. deep clean (so you don’t overdo it)
| Approach | Best for | Main trade-off |
|---|---|---|
| Quick routine | Odor prevention + consistency | May not clear deep vent buildup |
| Monthly/seasonal deep clean | Visible residue + recurring musty smell | More time and (for vents) more mess |
What can go wrong (and how to avoid it)
Most cleaning problems happen when people treat washing machines and dryers like interchangeable appliances. Small mistakes—like using the wrong chemicals or skipping vent checks—can prolong odors or create new performance issues.
Using cleaners not approved for washing machine rubber and internal components can accelerate degradation of seals and increase future residue.
Cleaning only the dryer lint trap won’t resolve restricted duct buildup beyond the trap area.
Using the wrong cleaner
Some household cleaners can damage finishes or rubber parts. For the washing machine, use cleaners labeled for washing machines or the exact product your manual recommends. For the dryer, avoid harsh solvents unless your manual explicitly approves them. When in doubt, stick to mild soap and a damp cloth.
Leaving water trapped in seals
Washing-machine odors often come from moisture that’s left behind after “quick wipes.” If you clean a gasket and don’t dry it, moisture can stay in folds and create recurring smells.
Overlooking the vent
A dryer vent can be the real culprit even when you’ve cleaned the lint trap. If drying time remains slow after lint-trap cleaning, the dryer vent/duct may have lint accumulation farther along the run or a connection that’s slightly loose/crushed.
Ignoring safety/energy issues
Vent maintenance is also a fire-safety issue. According to the U.S. National Fire Protection Association (NFPA), clothes dryers and related equipment are associated with an estimated ~2,900 home fires per year and about 5 deaths annually in the United States (reported in NFPA home fire safety reporting, year ranges vary by report). Also according to NFPA reporting, lint accumulation and failure to clean dryer equipment are recurring factors in ignition scenarios.
If you notice damage, persistent clogging, or vent pathways that are hard to access safely, stop and get professional help.
Verdict / tip (worth doing, but not for everyone)
If your goal is cleaner-smelling laundry and more reliable drying, this step-by-step routine is practical, low-cost, and grounded in how both appliances operate. The downsides: vent/duct cleaning can be messy, some models have harder-to-access filters/sensors, and disconnecting the dryer may be inconvenient or restricted by installation.
Routine cleaning of the washing machine gasket, detergent drawer, and dryer lint path reduces the primary drivers of odors and slow drying—moisture retention and airflow restriction.
Vent cleaning often requires safe disconnect steps, so the safest option is to stop and call a technician if the duct can’t be accessed without major disassembly.
Who should skip or limit vent access:
– If you can’t safely unplug/disconnect the dryer per the manual
– If your vent line looks damaged (kinks, crushed sections, or torn flexible duct)
– If the setup is in a location requiring special handling (tight enclosures, stacked systems where access is unsafe)
If you want the “highest impact” without vent work, focus on the washing machine gasket and drawer and keep the dryer lint trap rigorously clean between loads.

To keep both your washing machine and dryer performing at their best, focus first on residue sources (gasket and detergent drawer in the washer, lint path in the dryer), then escalate to the vent/duct if drying time remains slow. If you follow the steps in order and dry the gasket after cleaning, you’ll usually eliminate musty odors and improve drying consistency—without surprises.
Frequently Asked Questions
What’s the best way to clean a washing machine that smells bad?
Start by running an empty hot-water cycle with a washing machine cleaner or 1–2 cups of distilled white vinegar (skip fabric softener). Wipe down the rubber door gasket thoroughly, since mildew and detergent buildup often hide there. After the cycle, dry the drum and leave the door slightly open to prevent moisture from returning. For persistent odors, repeat the cycle and consider cleaning the detergent drawer and drain pump area if your model has access.
How do I clean my washing machine drum and detergent drawer safely?
Remove the detergent drawer and soak it in warm water with a mild dish soap solution, then scrub away residue with an old toothbrush. For the drum, wipe visible buildup first, then run a cleaning cycle using a product labeled for washing machines (or vinegar for lighter buildup). Avoid mixing vinegar and bleach in the same cycle, and always follow your washer’s manual for water temperature and cycle settings. Finish by wiping down the inside rim and door seal to keep the washer clean between wash loads.
Why does my dryer leave a musty smell even after I clean the lint trap?
A musty dryer odor can come from venting problems, moisture trapped in the duct, or buildup on the drum and moisture sensors. Clean the lint filter after every load, then vacuum the inside of the dryer drum and the vent area to remove fine lint that contributes to odors. Check the dryer vent hose for blockages and clean the vent line if airflow seems weak, since poor ventilation can keep clothes damp longer. Wipe the dryer’s moisture sensor bars with a soft cloth to improve drying performance and reduce smells.
How often should I deep clean a dryer and washing machine?
As a general rule, wipe down the door seal and run a washing machine cleaning cycle every 1–3 months, especially if you notice residue, mildew, or odors. For dryers, clean the lint trap after each use and do a deeper clean every 3–6 months by vacuuming the drum, lint housing, and vent connection. If you have heavy laundry use, pets, or allergies, you may need to clean more frequently to reduce lint buildup and maintain dryer efficiency. Regular cleaning helps prevent clogged vents, which can also improve drying times and safety.
Which products are best for cleaning washing machines and dryers without damaging them?
For most washing machines, use an odor-removing cleaner designed for washers or distilled white vinegar for maintenance cycles; choose products that are compatible with your washer type (HE, front-load, or top-load). For dryers, avoid harsh chemicals inside the drum and focus on vacuuming lint, wiping surfaces with a damp cloth, and using manufacturer-recommended cleaners if needed. If you use a dryer vent cleaning tool, keep it gentle to avoid damaging the vent hose or internal components. Always unplug the appliance before cleaning and follow the manufacturer’s instructions for safe care.
