Can You Machine Wash a Wool Blanket? Everything You Need to Know
Wool blankets are loved for their warmth, softness, and natural beauty. But when cleaning time comes, you might pause and wonder: can you safely toss your wool blanket in the washing machine? Let’s break down the answer, explore the risks and rewards, and learn the best way to keep your cozy blanket in tip-top shape.
The Short Answer: Yes, Sometimes—But With Caution
You can machine wash some wool blankets, but it’s not always the safest bet. Wool is a natural fiber that’s delicate and can easily shrink, felt, or lose its softness if washed improperly. Before you use your washing machine, always check the care label on your blanket. If it says “dry clean only,” stick to professional cleaning. If it allows machine washing, follow the manufacturer’s instructions precisely.
Understanding Wool: Why Special Care Is Needed
Wool fibers have a natural protective coating and unique structure that make them warm and breathable, but also sensitive to heat, agitation, and harsh detergents. Improper washing can lead to:
- Shrinking: Wool fibers contract when exposed to heat and agitation.
- Felting: The fibers can mat together, making the blanket stiff and less cozy.
- Distortion: The blanket could stretch or deform if handled roughly.
Gentle care helps preserve your blanket’s plush feel, insulation, and lifespan.
How to Machine Wash a Wool Blanket Safely
If your blanket’s care label gives the green light for machine washing, here’s how to do it without risk:
1. Read the Label First
- Always check the manufacturer’s care instructions.
- Look for terms like “machine washable wool,” “hand wash,” or “dry clean only.”
2. Prepare the Blanket
- Shake out dust and debris outside.
- Spot clean any stains with a gentle wool-safe detergent and cold water.
3. Choose the Right Cycle and Settings
- Use the delicate or wool cycle on your washing machine.
- Set water to cold or lukewarm—never hot.
- Select a low spin speed to minimize agitation.
4. Use the Right Detergent
- Opt for a detergent specially formulated for wool.
- Avoid regular laundry soaps or anything with bleach or enzymes, as they can damage the fibers.
5. Place the Blanket in the Machine
- Wash the blanket on its own or with similar wool items.
- Consider placing it in a large laundry bag to further reduce friction and tangling.
6. Monitor the Wash
- Remove the blanket as soon as the cycle ends to prevent creasing or musky odors.
7. Dry with Care
- Never wring out a wool blanket.
- Lay it flat on a clean, dry towel, reshaping it gently to its original dimensions.
- Roll the towel and blanket together to squeeze out extra water.
- Unroll and lay the blanket flat on a drying rack or another dry towel in a well-ventilated area.
- Avoid direct sunlight or heat sources like radiators, as these can cause shrinkage and fading.
Hand Washing: The Safest Bet for Most Wool Blankets
If you’re unsure or the label says “hand wash only,” it’s better to err on the side of caution. Here’s a quick guide:
- Fill a bath or basin with cool or lukewarm water.
- Add a small amount of wool detergent.
- Submerge the blanket and gently agitate with your hands.
- Let it soak for 10–15 minutes.
- Drain, then rinse in cool water—no wringing or twisting.
- Press out water gently, then use the rolling towel method to remove excess moisture.
- Dry flat, reshaping as needed.
Hand washing minimizes agitation, helping maintain the softness and structure of the wool.
Benefits of Machine Washing a Wool Blanket (When Allowed)
If your blanket is labeled “machine washable,” you gain several conveniences:
- Saves Time: No more soaking hands or waiting for a lengthy hand-wash process.
- Consistently Clean: Machines ensure an even, all-over clean.
- Low Effort: Just follow the settings and let the machine do the work.
However, the trade-off is the risk of wear and tear if instructions are not followed exactly.
Challenges and Risks
- Shrinking and Felting: The biggest risks of machine washing are irreversible shrinkage and texture change.
- Color Fading: Hot water or strong detergents may dull vibrant colors.
- Loss of Shape: Spin cycles can stretch or warp the blanket.
- Longevity: Machine washing too frequently could shorten the lifespan of your wool blanket.
Best Practices and Expert Tips
For the best results and to keep your wool blanket cozy for years, try these tips:
- Wash Infrequently: Wool is naturally odor- and stain-resistant. Air out your blanket regularly; only wash when necessary.
- Pre-treat Stains: Spot clean before a full wash, focusing on spills and problem areas.
- Storage: Store wool blankets in a cool, dry place. Fold neatly and use breathable storage bags to protect from moths.
- Use Conditioner: Some wool-safe detergents include conditioners that help keep the fibers soft.
- Avoid Fabric Softeners and Bleach: These harsh chemicals can damage wool.
- Freshen Between Washes: Hang your blanket outside (in the shade) on a breezy day to eliminate odors and revive fluffiness.
How to Handle a Shrunken or Felted Blanket
If your wool blanket emerges smaller or stiffer after a wash, all may not be lost:
- Soak it in lukewarm water with a gentle hair conditioner for 30 minutes.
- Gently stretch the blanket back to its original size while it’s still damp.
- Dry flat, reshaping as you go.
- Note: Severely shrunken or felted blankets may not return to normal, but these steps can help with mild cases.
When to Seek Professional Help
If your wool blanket is a family heirloom, particularly thick, expensive, or large, it may be wise to leave cleaning to the professionals. Dry cleaners specializing in wool have the expertise and equipment to handle delicate items safely.
Conclusion
You can sometimes machine wash a wool blanket, but caution is vital. Always check the label, use gentle cycles and cool water, and avoid harsh detergents. When in doubt, hand wash your blanket or turn to the pros. With the right care, your wool blanket will stay soft, beautiful, and warm for many seasons to come.
