The rubber seal around a front-load washer door is easy to miss. Its folds can catch lint, hair, detergent film and a surprising number of small objects. If the drum looks clean but the washer smells musty, this is a sensible place to check first.
Quick answer: Empty the washer. Gently open the gasket folds and remove any loose debris. Wipe the seal with a soft cloth and warm water, using a small amount of mild detergent only if your washer manual permits it. Wipe away any cleaner, dry every accessible fold and leave the door ajar when it is safe to do so. A tub-cleaning tablet is for a separate empty-drum cycle; it does not replace wiping the gasket by hand.
What Is the Door Gasket—and Why Does It Get Dirty?
The gasket is the flexible rubber seal between the door and the drum opening. It helps keep wash water inside the machine. Its lower fold can hold a little water after a cycle, while the creases collect lint and laundry-product residue. Closing the door before those areas dry can allow a musty smell to develop.
The goal is to remove accessible debris without damaging the rubber, then let it dry.
Before You Start
Have two soft cloths ready—one damp, one dry—plus warm water. Check your manual for approved seal cleaners. Avoid metal scrapers, stiff brushes and abrasive pads.
Do not mix bleach, vinegar, ammonia or a washer-cleaning tablet with another cleaner. Some manufacturers give model-specific directions for diluted bleach on the seal; those are not a universal recipe. Follow your own washer's instructions if ordinary wiping does not remove the residue.
How to Clean the Rubber Seal in 6 Steps
1. Empty and inspect the washer
Remove laundry and open the door. Check the inner lip, especially the bottom, for coins, hairpins, lint, pet hair or trapped fabric.
2. Gently open the folds
Ease back the accessible folds just enough to see inside. Do not tug hard or detach the gasket. Remove loose items and visible debris. If something is lodged behind the seal or you notice a tear, arrange service.
3. Wipe the gasket and door glass
Use a soft cloth dampened with warm water. Work around the entire seal, including the lower fold and the surface that touches the door. For stubborn detergent film, use a little mild detergent only if approved for your model. Wipe the door glass where it meets the seal, too.
4. Remove cleaner residue
Go over the area again with a clean, water-dampened cloth. Pay attention to creases where cleaning solution can sit. Avoid pouring water directly into the folds or spraying liquid toward electrical parts.
5. Dry every accessible fold
Dry the lower groove, sides of the seal and door glass. Leave the door slightly open afterward if it is safe around children and pets.
6. Check the result
Look for remaining debris, standing water, damage or a smell that persists once the seal is dry. If the gasket is clean but the washer still smells, the source may be the dispenser, filter or drain—not the seal. See our guide to why a washing machine smells for the next checks.
What About Black Spots or a Strong Musty Smell?
Dark marks are not always removable dirt. Start with gentle wiping. If your manual specifies a treatment for stains or mildew, follow its dilution, contact-time, rinsing and glove instructions. Never combine treatments.
If marks or odor remain after approved cleaning, or the seal is cracked, loose or leaking, contact the washer manufacturer or a qualified technician. Repeatedly scrubbing a damaged gasket may make a leak worse.
Does a Washer Cleaner Tablet Clean the Gasket?
Not by itself. A washer-cleaning cycle treats the machine's water-contact areas, but the exposed folds of the door seal still need a separate wipe and dry. After cleaning the gasket, you can run your washer's approved empty maintenance cycle if the manual calls for one.

Confirm your washer's cleaner and cycle requirements before use. For the complete machine-cleaning routine, read How to Clean a Washing Machine.
How Often Should You Wipe the Seal?
A quick look and dry wipe after laundry can catch trapped items before they sit in the fold. Do a more thorough wipe when you notice residue or odor, and follow your washer manual's maintenance schedule. Frequency will vary with how often you wash, how much detergent you use and how quickly the machine dries.
To keep the area fresher between cleanings, move wet laundry promptly, measure detergent rather than pouring by eye, wipe visible water and let the door and dispenser air out when household safety allows.
Frequently Asked Questions
Can I remove the rubber gasket to clean behind it?
Do not remove or detach it for routine cleaning. Clean only the folds you can reach gently. A damaged or incorrectly refitted seal can leak; ask a qualified technician if something is trapped behind it.
Should I put a cleaning tablet directly on the seal?
No. Use the tablet only in an approved empty-drum cleaning cycle according to the product label and washer manual. Wipe the gasket separately.
Why does the gasket still smell after I wipe it?
Moisture may remain deep in the lower fold, or the odor may come from another part of the washer. Dry the accessible seal, then check the dispenser, user-accessible filter and drain using your model's instructions.
A Small Habit That Makes a Difference
The most useful gasket routine is simple: check the fold, remove debris, wipe gently and dry thoroughly. Pair that hands-on step with the maintenance cycle recommended for your machine, and investigate persistent smells or leaks instead of adding more cleaner.
