Blankets are an essential part of making a bed comfortable and cozy. However, if not cleaned regularly, they can accumulate dirt, dust mites, and other allergens that can cause issues for those who are sensitive. So how often is it recommended to wash your blankets?
How Often Should You Wash Different Types of Blankets?
The recommended washing frequency depends on the type of blanket:
Cotton Blankets
Cotton blankets should be washed every 2-3 weeks during warmer months when they are in regular use. During cooler months when they aren’t used as much, every 6 weeks is sufficient. The main reason to wash cotton blankets regularly is to remove body oils, sweat, and dead skin cells that build up over time. Allowing these to remain in the fabric can reduce the blanket’s ability to insulate and make it feel stiff or rough on the skin.
Wool Blankets
Wool blankets only need to be washed 2-3 times per year, or when they are visibly dirty. Wool has natural lanolin oils that allow the blanket to repel dirt and dust mites on its own between washes. Too much washing strips away these oils and shortens the life of a wool blanket. Wool also takes much longer to fully dry than cotton, so frequent machine washing is not recommended.
Polyester Filled Blankets
Like wool blankets, polyester blankets only need washing a few times a year. The synthetic polyester filling does not absorb odors and oils as much as natural fibers. Plus, polyester filling takes a long time to dry fully, so washing often is not ideal. Polyester blankets can be washed 2-3 times per year or when visibly dirty.
Electric Blankets
Electric blankets should be washed 3-4 times per year according to manufacturer instructions. Do not wash the electric controller unit, only the removable blanket. Check the product label, as some may only be surface washable due to the internal wiring. When washing, use a gentle cycle and mild detergent to avoid damaging the wiring over time.
Down-Alternative Comforters
Down-alternative comforters can be washed 2-3 times per year, or when they appear dirty. The synthetic fill does not absorb odors and oils readily but regular washing helps refresh the comforter. Use a mild detergent and gentle cycle, then dry thoroughly to re-fluff.
Duvet Inserts
Duvet inserts with down or down-alternative fills should be washed 2-3 times per year. Inserts with cotton, wool, or other natural fills can be washed more frequently, every 3-6 weeks. Check the product label for any special washing instructions.
Quilts
Quilts can be washed 1-2 times per year for lightweight ones, and 1-2 times every 2 years for heavier quilts. The quilting stitches and batting material used impacts how much washing a quilt can handle before it starts to wear. Check the product label and opt for gentle cycles and air drying when possible.
Weighted Blankets
Weighted blankets should be washed every 1-2 weeks to remove odors, oils, and sweat. The weight is evenly distributed through beads, often poly pellets, so it can withstand regular machine washing. Use a mild detergent and gentle cycle, then air dry completely before reusing. Do not dry clean.
Signs it’s Time to Wash Your Blankets
Aside from following general washing recommendations, there are some signs that indicate it’s definitely time to wash your blankets:
- Visible dirt or stains
- Dust, pet hair, lint accumulation
- Odor – smells like body odor, sweat, smoke, etc.
- Becomes stiff or rough feeling
- No longer feels warm – reduced insulation
- Dander, dust mites, or bug infestation signs
Pay attention to these signs and wash your blankets promptly when needed, regardless of when they were last washed. A visibly dirty or smelly blanket should always be laundered right away.
Washing Methods for Blankets
Machine Washing
Most blankets today are machine washable and dryable. When using a washing machine:
- Use a mild, hypoallergenic detergent.
- Wash on a gentle or delicate cycle with cold water.
- Load the blanket loosely and evenly distribute.
- Use an extra rinse cycle to remove all detergent.
- Air or tumble dry on low if machine drying.
Hand Washing
For delicate blankets like wool, cashmere, antique quilts, etc. hand washing is recommended. To hand wash:
- Fill sink or tub with cool water and mild detergent.
- Submerge blanket and allow to soak for 15 minutes.
- Drain dirty water and refill with clean cool water.
- Gently press and agitate blanket to release dirt.
- Drain and repeat rinse cycle until water runs clear.
- Roll blanket in towels to remove excess moisture.
- Lay flat on drying rack, rotate periodically until fully dry.
Dry Cleaning
Dry cleaning may be required for blankets made of silk, rayon, or other delicate fabrics. Check the product label to see if dry cleaning is recommended by the manufacturer. If hand washing could damage the blanket, take it to a professional rather than attempting to machine wash at home.
Drying Blankets Thoroughly
It’s important to dry blankets completely before remaking the bed or storing them away. Any remaining moisture can allow mold and mildew growth in stored blankets. It also feels damp and uncomfortable to sleep with a blanket that didn’t get fully dried. Here are tips for drying blankets:
- Always check product labels for drying recommendations.
- Shake blankets outdoors right after washing to release moisture.
- Machine dry on a low heat setting, removing promptly after cycle ends.
- Air dry on a clothes drying rack or clothesline.
- Layer dry towels under the blanket to wick away moisture.
- Rotate, flip, and fluff blankets periodically as they air dry.
- Make sure inner layers and corners are completely dry.
If using a clothes dryer, dry for 5-10 minutes then check if the blanket is dry to avoid overheating. For quicker air drying, choose a warm sunny day or use a fan to circulate air around the blanket.
Storing Blankets Properly Between Uses
Proper storage between washes can help keep blankets cleaner longer. Here are some storage tips:
- Store blankets in breathable cotton or mesh bags.
- Use cedar chips or cedar balls to repel moths and insects.
- Vacuum storage bags remove excess air and create a protective seal.
- Fold or roll blankets neatly to minimize creasing.
- Store in clean, dry areas like a closet or chest.
- Avoid attics, basements, and garages if damp or dusty.
- Wash blankets before seasonal storage to remove oils and dirt.
Improper storage that traps moisture or humidity can lead to mildew growth. Make sure blankets are completely dry before storing away for the season. Keeping blankets loosely folded in breathable bags will minimize creasing as well.
Cleaning Different Types of Blanket Stains
Even with proper washing, stains can still happen on blankets sometimes. Here are tips to clean common blanket stains:
Bodily Fluids – Blood, Sweat, Urine
- Rinse with cold water and soak in enzymatic detergent for 30+ minutes before washing.
- Launder with detergent and 1 cup white vinegar.
- Use an oxygen-based bleach alternative if needed.
Food, Coffee, and Juice
- Scrape off solids gently with a dull knife.
- Blot up excess liquid immediately.
- Spray with prewash stain remover or enzymes.
- Wash using detergent and 1/2 cup white vinegar.
Ink and Marker
- Spray isopropyl alcohol on the stain.
- Rub gently with a clean cloth or use cotton swabs.
- Rinse and repeat until no more ink transfers to the cloth.
- Wash with detergent and rinse thoroughly.
Mildew and Mold
- Spray concentrated white vinegar or lemon juice on stains.
- Let sit 30 minutes then rinse and launder with detergent.
- For tougher mold, make a borax paste and scrub into stains before washing.
Dust and Dirt
- Vacuum blankets before washing to remove surface dust and dirt.
- Use a lint roller on areas with pet hair or lint buildup.
- Spot clean visibly soiled areas with a damp cloth and mild detergent.
- Pretreat any ground-in dirt stains before washing.
Catching stains early and not allowing them to set makes removal easier. Always check product care labels before attempting to clean blanket stains at home. For antique, handmade, or delicate blankets, professional dry cleaning may be the safest stain removal method.
Disinfecting Blankets
During times of illness, regularly disinfecting the home is important. This includes disinfecting reused blankets. Here are tips to disinfect blankets:
- Machine wash using hot water and regular laundry detergent.
- For bleach-safe blankets, add 1/2 cup bleach to the wash cycle.
- Vinegar is a natural disinfectant – use 1 cup in the rinse.
- Tumble dry on high heat or hang outside in direct sunlight.
- Steam heat also kills germs – use a garment steamer on blankets.
- Store cleaned blankets sealed in vacuum bags between uses.
It’s important to consult product care instructions before using harsher methods like hot water or bleach. Vinegar, sunlight, and steam can effectively disinfect more delicate blankets.
Extending the Life of Your Blankets
To get the most use out of blankets and avoid frequent costly replacements, here are tips to make them last:
- Inspect regularly for wear, holes, or damage after use.
- Mend minor damage like small holes right away before they expand.
- Use a washable blanket cover to protect the blanket itself.
- Follow all product care instructions closely when washing.
- Air dry when possible or tumble dry on low.
- Hang blankets outdoors to freshen in the sunlight periodically.
- Fold and store neatly in breathable storage bags.
- Have antique quilts or special blankets professionally cleaned.
Knowing When It’s Time to Replace Your Blanket
No matter how well you care for them, blankets do wear out over time. Here are signs that indicate it’s time to replace an old, worn out blanket:
- Thin, holey fabric with tears or rips.
- Broken or tangled internal wiring (for electric blankets).
- Lumping, clumping, or bare spots in the filling.
- No longer provides adequate warmth.
- Remains stiff or scratchy after washing.
- Pervasive stains that won’t come out.
- Visible damage from mold, mildew, or insects.
- Scorched areas or charring from catching on fire.
While it can be hard to part with a cherished old blanket, using severely damaged or non-functional blankets can impact your comfort and even become a safety hazard. Be objective when assessing the true condition and don’t take risks with safety due to an emotional attachment.
