Bad smells usually come out of bedding when you wash it with the right amount of detergent, dry it fully, and fix the source of the odor. The related guide, How to Get Old Person Smell Out of Bedding?, covers the fabric and cleanup variables behind the related pet or odor problem. Start by checking the care label. Then treat stained areas, wash the bedding in the warmest water the label allows, and make sure every layer is completely dry before putting it back on the bed.
Do not cover the smell with fabric spray. The related guide, How Do I Remove Bad Odor from My Bed?, covers the fabric and cleanup variables behind the related pet or odor problem. Fragrance may hide the odor for a short time, but it will not remove body oils, pet messes, dampness, or detergent buildup.
Find the Source of the Smell First
Knowing what caused the odor helps you choose the right cleaning method.
Common causes include:
- Sweat and body oils
- Damp bedding left in the washer
- Bedding stored before it was fully dry
- Pet hair, drool, or accidents
- Food and drink spills
- Urine leaks
- Smoke or cooking odors
- Too much laundry detergent
- A dirty washing machine
- Moisture in the mattress, pillow, or bedroom
Smell each bedding layer separately. Compare the best fabric deodorizers for bedding only after confirming the material and odor source. Check the sheets, pillowcases, mattress protector, comforter, pillows, and mattress separately.
Also look for damp patches, stains, or visible growth. If an item has heavy damage or cannot be cleaned according to its care instructions, replacement may be the more practical choice.
Remove Bad Smells From Washable Bedding
1. Read the Care Label
Check the care label before washing, soaking, bleaching, or using heat. Bedding materials do not all need the same treatment.
Cotton sheets may allow warm or hot water. Microfiber often needs cooler water and lower dryer heat. Wool, silk, down, weighted blankets, and some quilted items may need special care.
Large comforters also need enough room to move inside the washer. A tightly packed machine may leave detergent, dirt, and odors trapped in the filling.
2. Shake Out Hair and Loose Dirt
Take the bedding outside or over an easy-to-clean floor. Shake it gently to remove dust, crumbs, and loose pet hair.
For pet-friendly homes, use a lint roller, rubber brush, or vacuum attachment before washing. Wet pet hair can stick to fabric and collect inside the washing machine.
3. Treat Smelly or Stained Areas
Apply a laundry stain remover or a small amount of liquid detergent to the affected area. Follow the product directions and test it on a hidden spot when needed.
Let the treatment sit for the time listed on the label. Do not leave strong cleaners on fabric longer than directed.
For urine, vomit, or pet accidents, use a laundry product made for that type of organic stain. Check that it is suitable for the fabric and washing machine.
4. Use the Correct Amount of Detergent
More detergent does not always make bedding cleaner. Too much can leave a coating that traps body oils and develops a sour smell.
Follow the detergent label and adjust for:
- Load size
- Soil level
- Water hardness
- Washer type
High-efficiency machines usually need a low-sudsing detergent. Make sure the detergent is marked as suitable for your washer.
Do not pack the drum tightly. Sheets and blankets need room to move through the water.
5. Choose a Suitable Wash Cycle
Use the warmest water allowed by the care label. Warm water can help loosen body oils, but hot water may shrink fabric, fade colors, or damage special fills.
A normal or bedding cycle works for many sheets and washable protectors. Bulky comforters may need a large-capacity machine and a bulky-item cycle.
An extra rinse can help when bedding smells like detergent or feels coated. It can also be useful for thick blankets that hold rinse water.
6. Add an Odor-Removing Laundry Product When Needed
A laundry sanitizer, oxygen-based bleach, odor remover, or enzyme laundry product may help with stubborn smells. Use only products approved for the bedding material and follow the label carefully.
White vinegar is sometimes used in the rinse cycle to help remove detergent buildup and mild sour odors. Check the washer instructions before using it, and do not pour vinegar directly onto delicate fabric.
Never mix vinegar, ammonia, or other cleaners with chlorine bleach. Mixing cleaning products can create dangerous fumes.
7. Dry the Bedding Completely
Bedding that feels only slightly damp can begin to smell again.
Dry the item according to its care label. Sheets usually dry faster when removed from the washer promptly and shaken before going into the dryer.
For thick comforters and pillows:
- Use the heat level listed on the care label.
- Pause the cycle and turn the item several times.
- Check the center, seams, and corners for moisture.
- Run another low-heat or air cycle when needed.
Air drying can help freshen bedding, but thick items may take a long time to dry indoors. Place them where air can reach both sides. Do not fold or store them until the filling is dry all the way through.
How to Remove Specific Bedding Odors
Sour or Musty Smells
A sour or musty smell often comes from damp fabric, detergent buildup, or bedding left in the washer too long.
Wash the item again rather than placing it straight into the dryer. Use a normal amount of detergent, choose the warmest safe water, and add an extra rinse.
Move the bedding to the dryer or drying rack as soon as the wash cycle ends.
If the smell returns after washing, check the washer drum, door seal, detergent drawer, and drain filter according to the washer manufacturer’s instructions. The related guide, Why Does My Bedding Still Smell After Washing?, covers the fabric and cleanup variables behind the related pet or odor problem.
Sweat and Body Odor
Body oils can collect on sheets, pillowcases, and duvet covers, especially in warm bedrooms or shared beds.
Make bedding smell fresh by removing odor sources, washing each layer correctly, drying fully, airing the bed, and using fragrance only after cleaning.
Pretreat the areas that touch the face, neck, and upper body. Wash the bedding regularly and avoid using too much fabric softener. Softener can coat fibers and make it harder to rinse away oils.
Hot sleepers may find it easier to manage odors with lightweight, washable layers. A removable duvet cover is simpler to wash than a full comforter.
Pet Odors
Remove as much hair as possible before washing. Treat visible spots and use a detergent or laundry additive intended for pet odors when the care label allows it.
Wash pet blankets separately when they are heavily soiled. Clean the washer afterward if hair or debris remains in the drum or door seal.
A washable throw placed over the pet’s usual sleeping spot can protect the main comforter and make laundry day easier.
Urine Odors
Blot fresh moisture with clean towels. Do not rub the liquid deeper into the fabric.
Rinse or treat the area according to the care label, then use a laundry product made to break down urine residue. Wash the item promptly and check the smell before drying it with heat. Heat may make some stains and odors harder to remove.
For repeat leaks, use a washable absorbent pad over a waterproof mattress protector. Make sure both products fit the mattress and can be washed in your machine.
Smoke and Cooking Smells
Air the bedding outdoors or near an open window when conditions allow. Then wash it according to the care label.
Heavy comforters, foam pillows, and delicate items may hold smoke longer than sheets. Check the manufacturer’s cleaning guidance before soaking or washing them.
The odor may return if smoke is still present in the bedroom, curtains, carpet, mattress, or upholstered furniture.
Storage Smells
Bedding stored in a closed box or closet may smell stale even when it looks clean.
Wash or air it before use. Clean the storage area and make sure it is dry. Store bedding only after it has cooled and dried fully.
Use breathable storage bags for everyday linens. Avoid sealing damp bedding in plastic.
What to Do When Bedding Still Smells After Washing
If the smell remains, check for these common problems:
The Washer Was Too Full
A packed washer cannot move water and detergent through thick bedding. Rewash the item in a larger machine or divide the load.
Too Much Detergent Was Used
Detergent residue can smell sour and make fabric feel stiff or sticky. Run another wash or rinse using the amount recommended for the load.
The Bedding Did Not Dry Fully
Thick seams, corners, and filling can stay wet after the surface feels dry. Dry the item again using the care label instructions.
The Washing Machine Needs Cleaning
A dirty washer can transfer odors to clean bedding. Follow the machine manufacturer’s cleaning steps. Pay attention to the detergent drawer, door seal, drum, and filter.
The Smell Is Coming From the Mattress or Pillow
Remove all bedding and inspect the bed itself. A mattress protector may need washing, and pillows may need cleaning or replacement depending on their care instructions and condition.
Do not put fresh sheets over a damp mattress. Let the surface dry fully and address the source of the moisture first.
How to Freshen Bedding That Cannot Go in the Washer
Some quilts, decorative pillows, foam items, and delicate blankets cannot be machine washed.
Start with the care label. Depending on the item, you may be able to:
- Air it in a shaded, well-ventilated place.
- Vacuum the surface with a clean upholstery attachment.
- Spot-clean small areas with an approved cleaner.
- Use a removable washable cover.
- Take it to a professional cleaner.
Do not soak foam, down, wool, silk, or decorative bedding unless the manufacturer says it is safe. Moisture trapped inside thick materials can cause stronger odors.
How to Keep Bedding Smelling Fresh
Wash sheets and pillowcases often enough for the room, sleeper, and season. Bedding used by pets, children, hot sleepers, or several people may need more frequent washing.
A simple routine can help:
- Let the bed air before making it in the morning.
- Keep wet towels and damp clothes off the bed.
- Wash spills and accidents promptly.
- Use washable pillow and mattress protectors.
- Clean pet bedding regularly.
- Move washed bedding to the dryer without delay.
- Dry every item completely before use or storage.
- Clean the washing machine as directed.
- Avoid using more detergent than needed.
For guest rooms, wash bedding before storing it and again when it has been unused for a long time. In dorms, RVs, and small bedrooms, improve airflow when possible because bedding may dry more slowly in tight spaces.
What to Avoid
Avoid these common mistakes:
- Spraying perfume over dirty bedding
- Putting damp bedding back on the bed
- Mixing household cleaners
- Using chlorine bleach without checking the care label
- Drying delicate fabric on high heat
- Overfilling the washer or dryer
- Using too much detergent or fabric softener
- Folding thick bedding while the center is still damp
- Ignoring odors coming from the mattress or washing machine
Frequently Asked Questions
Can I wash smelly bedding with baking soda?
Baking soda may help with some mild odors, but it is not suitable for every fabric or washer. Check the bedding care label, washer instructions, and baking soda package before using it. Do not combine cleaning products unless their labels say the mixture is safe.
Why do my sheets smell bad after washing?
The washer may be overloaded, the sheets may contain detergent buildup, or they may have stayed wet too long after the cycle ended. A dirty washing machine can also transfer odors. Rewash the sheets with the correct amount of detergent and dry them promptly.
Can I use vinegar to remove bedding odors?
White vinegar may help remove mild odors and detergent residue when used correctly in some washing machines. Check the washer instructions and fabric care label first. Never mix vinegar with chlorine bleach.
How do I remove a musty smell from a comforter?
Check the care label, then wash the comforter in a machine large enough for it to move freely. Dry it completely, including the filling at the center and corners. If it cannot be machine washed, follow the manufacturer’s cleaning directions.
Why does my bedding smell again after one night?
Body oils, sweat, pet odors, or a smell in the mattress or pillow may be transferring back to the clean bedding. Check every layer of the bed and wash protectors, pillow covers, and other washable items.
Is it safe to sleep on slightly damp bedding?
It is better to let bedding dry fully before using it. Damp sheets and blankets can feel uncomfortable and may quickly develop a stale smell. Check thick seams and filling because they often dry more slowly than the surface.
How can I keep stored bedding from smelling stale?
Wash and dry the bedding fully before storing it. Keep the storage space clean and dry, and use a breathable container when practical. Air or wash the bedding before use if it has been stored for a long time.
